Five patients were examined suffering from bilateral paramedian thalamic infarction, caused by occlusion of the posterior paramedian thalamo-subthalamic arteries, when they begin from one single pedicle. All cases began with obnubilation or transitory coma, followed by hypersomnia. Four patients showed vertical gaze paralysis, and the fifth vertical nystagmus. In three cases, nuclear lesion of the III cranial nerve was observed along with alteration of the photomotor reflexes, and there was miosis in one case. All were suffering from weakness in one or another limb or facial paresis and generalised acute hypotonia: only one patient had hemihypostesia. All five had dysarthria, ataxy and dysmetria, one had asterixis and two spasmodic crying. Between 5 and 12 months later, one had akinetic mutism and vertical gaze paralysis as the most noteworthy signs. The neuroradiological images show a bilateral ischemic lesion in the paramedian thalamic region, which extends in some cases to the anterior nucleus and in one case to the pulvinars; the lesion continues through the subthalamic regions and the medial part of the mesencephalic tegmentum, with a clear extension to the medial region of the cerebral peduncles in three cases and to the tectum in one case.

We attempted to correlate the marked neurological asymmetry observed in two amyotrophic lateral sclerosis patients with their histopathological lesions. Patient 1, a 52-year-old man, developed dysarthria and dysphagia, followed by muscle weakness in the left arm and then of the left leg. Patient 2, a 44-year-old man, developed muscle weakness in the left hand, left leg, tongue with left-sided predominance, right hand and right leg in that order of progression. Both patients exhibited moderate to marked left-sided predominant involvement of the lower motor neuron system, accompanied by retained or hyperactive deep tendon reflexes on the left side in the early stage of their illness. Most of the asymmetry in the lower motor neuron system involvement persisted until the death of the patients. Histopathological examinations, including semiquantitative analysis, revealed that both patients exhibited left-sided predominant degeneration of the lower motor neuron system at those spinal cord levels where the neurological asymmetry was of a moderate to marked degree. In addition left-sided predominant degeneration of the lateral corticospinal tracts was seen in both patients and right-sided predominant involvement of Betz cells in the leg area of the motor cortex of patient 1. This pattern of both the neurological and histopathological asymmetry suggested the probable existence of an intimate somatotopically related linkage between the upper motor neuron system degeneration and lower motor neuron system degeneration in both patients.

A 61-year-old Caucasian man presented with otalgia, dysarthria, and weight loss. Neurological examination revealed palatal hypomotility, and weakness of the facial and tongue muscles. Magnetic resonance imaging of the head demonstrated the presence of a soft tissue mass in the clivus. Histologic examination of resected tumor disclosed well-differentiated thyroid follicles that invaded the local osseous tissues. Physical examination and radioiodine images of the thyroid gland were normal. The serum thyroglobulin concentration was markedly elevated (1011 ng/mL). A 0.9-cm well-differentiated benign-appearing left thyroid lobe follicular neoplasm with a thick fibrous capsule was found following diagnostic thyroidectomy. This report illustrates that clinically significant distant metastases can arise from occult follicular thyroid neoplasms that, according to standard histologic criteria, are benign. The presence of a thick fibrous capsule, even in the absence of vascular or capsular invasion, may identify follicular neoplasms that have metastatic potential.

We administered local botulinum toxin injections on the leg adductors of 12 patients with spastic paraparesis (9 patients with HAM, 2 patients with spinal spastic paraparesis, 1 patient with an identified degenerative disease). Two of them were wheelchair-bound and the other patients could walk with or without help. The patients were assessed by the time to walk 10 m and the spasticity score which was derived from the degree of muscle tone and spasm frequency of leg adductors. After the initial injection, 7 of the 12 patients improved spasticity scores and 8 of the 10 patients could walk 10 m within a shorter time. The time to walk 10 m was markedly shortened in moderate cases. However, one patient complained of leg weakness and the time to walk 10 m was prolonged. Five of the 12 patients received injections 3 to 7 times, and were followed up for a mean of 16.2 months. In 4 of the 5 patients, repeated injections could maintain the improvement of spasticity score and time to walk 10 m. However, injection was discontinued in one patient because of leg weakness. The other side effects were pain and swelling at the injected site and dysarthria. However, these side effects were slight and transient and did not require treatment. No other systemic side effects were observed. In conclusion, the beneficial effects of botulinum injections to spastic paraparesis were (1) improvement of objective symptoms in mild cases, (2) improvement of ADL in moderate cases, and (3) improvement of objective symptoms and ease of nursing care in severe cases. Furthermore, we confirmed the long-term efficacy and safety of botulinum toxin.

We report a 54-year-old man with progressive proximal muscle atrophy and gynecomastia. The patient had an insidious onset of weakness in his lower extremities at age 14, in that he noted a difficulty in standing up from a chair. Soon after he noted some difficulty in climbing up stairs. At age 35, he noted weakness in his arms; his weakness slowly progressed in that he became unable to walk or stand alone before 40 years of age. He also noted gynecomastia at that age. He was admitted to our hospital for the work up on September 16, 1993, when he was 54-year-old. On admission, he was alert and oriented; his BP was 150/70 mmHg; he had bilateral gynecomastia, however, no other skeletal deformities were found. On neurologic examination, he was mentally sound without dementia, and his higher cerebral functions were normal. Cranial nerves also appeared intact without facial atrophy, dysarthria, or dysphagia; no atrophy was noted in the tongue. He had marked muscle atrophy in both upper and lower extremities more marked in the proximal portions; muscle strength was approximately in the range of 2/5 to 3/5 in the proximal parts, and 4/5 in the distal parts in both upper and lower extremities. No fasciculation was noted; muscle tone was flaccid; no ataxia was present. Deep reflexes were either lost or markedly diminished. No Babinski sign was noted. Sensation was intact. Laboratory examination revealed normal blood counts; serum CK was slightly increased to 131 IU/l; ECG showed complete right bundle branch block; EMG revealed no active units in the right biceps brachii, deltoid, quadriceps femoris, and triceps surae muscles; in other muscles tested, motor unit potentials of low amplitude and short duration were seen; in the right tibialis anterior muscle, however, motor unit potentials with an amplitude up to 6 m V were also seen. Nerve conduction velocities were normal. A diagnostic procedure was performed. He was discussed in the neurological CPC, and the chief discussant arrived at the conclusion that this patient had Becker type of progressive muscular dystrophy. In her differential diagnosis, the possibility of Kennedy-Alter-Sung syndrome was discussed because this patient had gynecomastia. However, the discussant excluded that possibility because of absence of both bulbar symptoms and typical neurogenic changes in his EMG. The diagnostic procedure was a muscle biopsy on the left tibialis anterior muscle. Histologic observation on HE stained specimens revealed marked inequality in the muscle fiber diameters, increase in endomysial nuclei, proliferation of connective tissue, and fiber splitting.(ABSTRACT TRUNCATED AT 400 WORDS)

We report a 74-year-old man with a lung cancer, who developed right leg weakness, neurogenic bladder, and multiple cranial nerve palsies. The patient was well until December of 1992, when he was 74-year-old, when he noted transient double vision; in February of 1993, he noted numb sensation and weakness in his right leg. Later in the same month, he developed overflow incontinence of urine and weakness in his right face. He also noted deafness in his left ear (he had a marked loss of hearing in his right ear since childhood because of otitis media). His weakness in his right leg had progressed, and he was admitted to our service on March 19, 1993. On admission, he was afebrile and BP was 130/50 mmHg. General physical examination was unremarkable. On neurologic examination, he was alert and oriented to all spheres; no dementia was noted nor were detected aphasia, apraxia, and agnosia. His optic fundi were unremarkable; ocular movement appeared normal, however, he complained of diplopia in far vision. Sensation of the face was intact. He had right facial palsy of peripheral type; he was unable to close his right eye, and Bell's phenomenon was observed on attempted eye closure. On the left side, he had facial spasm. He had marked bilateral deafness. He had no dysarthria or dysphagia. The remaining of the cranial nerves were intact. Motor wise, he was unable to stand or walk alone; weakness did not appear to account for his difficulty in gait; manual muscle testing revealed 4/5 weakness in his tibialis anterior muscle, 1/5 in the peroneus longus, 0/5 in his extensor hallucis longus and extensor digitorum longus, all on the right side. Brachioradial and quadriceps femoris reflexes were increased to 3/4; plantar response was equivocal on the right side, and flexor on the left. Sensory examination revealed loss of touch and pain sensation in the L5 and S1 distributions in his right leg: vibration and position sensations were also diminished in his right foot. He had overflow urinary incontinence with loss of bladder sensation. Marked nuchal stiffness was noted, however, no Kernig's sign or eye ball tenderness was present. Pertinent laboratory findings were as allows; WBC 8,100/microliters, Ht 42.5%, platelet 326,000/microliters, TP 6.8 g/dl, BUN 16 mg/dl, creatinine 0.54 mg/dl, glucose 95 mg/dl, Na 136 mEq/l, K 4.4 mEq/l, Cl 100 mEq/l; liver profile was normal; CEA 436.6 ng/ml, CA19-93 U/ml; urinalysis was normal.(ABSTRACT TRUNCATED AT 400 WORDS)

Hereditary haemochromatosis is characterised by excessive parenchymal iron deposition, particularly in the liver. Usually hereditary haemochromatosis is not associated with neurological symptoms and iron deposition in the brain has not previously been described as a pathological phenomenon. A patient is reported with hereditary haemochromatosis and a syndrome of dementia, dysarthria, a slowly progressive gait disturbance, imbalance, muscle weakness, rigidity, bradykinesia, tremor, ataxia, and dyssynergia. The findings on MRI of a large signal decrease in the basal ganglia, consistent with excessive iron accumulation, indicate a causal relation to the symptoms. Although the neurological symptoms did not improve in our patient, hereditary haemochromatosis should be considered in the differential diagnosis of parkinsonian syndromes, because complications of iron induced organ injury may be prevented by phlebotomy.

We report a 65-year-old woman with progressive dysarthria, dysphagia, weakness, and gait disturbance. The patient was well until 59 years of age (January of 1986) when she noted bilateral ptosis. One year later, she noted a gradual onset of difficulty in speech (articulation). Her speech slowly deteriorated and she noted weakness in chewing power and difficulty in swallowing in addition. In October 1987, she developed emotional incontinence. In January of 1988, she started to drag her left foot. She was admitted to our hospital on June 13 of 1988. On admission, she was alert and general physical examination was unremarkable. Neurologic examination revealed no dementia; her higher cerebral functions appeared intact. Ptosis was present bilaterally more on the right. She showed difficulty in opening her eyes on command; no contraction of the frontal muscles was seen upon attempted eye opening. There was a moderate limitation in the vertical gaze. Forced laughing and crying were seen. Facial muscles were moderately weak without apparent atrophy. The movement of the soft palate was very weak, and swallowing disturbance was more prominent for liquid staff. The tongue appeared somewhat small, however, no fasciculation was noted. Her step was small and the posture was stooped. Retropulsion was present, however, Romberg's sign was absent. No muscle atrophy was apparent, however, diffuse mile to moderate muscle weakness was noted in all four limbs. Cerebellar sign was absent. Deep tendon reflexes were exaggerated bilaterally, and Babinski sign was present on the left side. Sensation was intact. Routine blood tests were unremarkable as was a cranial CT scan. Her ptosis did not improve after 10 mg of edrophonium injection. CSF was also normal. She was transferred to another hospital but her neurological disabilities further progressed. In 1989, she was totally unable to move her limbs; she could only move her eyes; still consciousness was clear without dementia. She developed respiratory difficulty and expired on July 25, 1992. She was discussed in a neurological CPC, and the opinions were divided into ALS and primary lateral sclerosis (PLS). The chief discussant arrived at the conclusion that the patient might have had the pyramidal form of ALS. Postmorten examination revealed marked myelin pallor in the anterior as well as lateral corticospinal tracts. Pyramidal tract degeneration was prominent starting at the level of the cerebral peduncle and was continued to be seen until the level of lumbar cord. The number of anterior horn cells showed only slight decrease in the cervical level, however, it was normal in the lumbar cord.(ABSTRACT TRUNCATED AT 400 WORDS)

Ophthalmoplegia and dementia are not usually observed in patients with amyotrophic lateral sclerosis. We report the case of a 60-year-old female with ophthalmoplegia and frontal-type dementia which appeared at an early stage of her illness that presented with dysarthria and weakness in the upper extremities. Notable autopsy findings in the central nervous system were, in addition to the degeneration of upper and lower motor neurons, moderate neuronal loss and spongy degeneration in layer II of the frontal cortex with prominent astrocytosis, and moderate neuronal loss with astrocytosis in both the substantia nigra and the red nucleus. Central chromatolysis of a few neurons in the oculomotor nucleus was seen. This case is considered to be a new subtype of motor neuron disease.

A patient with a unique form of large granular lymphocytosis and multiple cranial neuritis is reported. The patient presented with facial weakness, diplopia and dysarthria. An increase in large granular lymphocytes (LGLs) was seen in blood (1.8 x 10(9)/l), CSF (237/microliters) and bone marrow (20% in a normocellular bone marrow). The phenotype of the LGLs in CSF, blood and bone marrow was CD2+ CD3+ CD4+ CD8- CD16- CD56- and CD57-. The unique features of this case include the CD4+ phenotype, the relative abundance of CSF LGL and the clinical presentation.
