Cortical brain lesions were identified on MRI and CT in 14 patients with a variety of diseases. Each of these patients developed neurologic symptoms, the most prominent of which were seizures, depressed mental status, and blurred vision or cortical blindness. Both the imaging and the neurologic abnormalities resolved spontaneously within a period ranging from 5 to 30 days. Due to location and evolution of the lesions over time we hypothesize that they are secondary to small cortical venous thromboses.

We reported a case of 21 years old man of chronic toluene intoxication with abnormal intensity areas on MRI in cerebral white matter, basal ganglia, internal capsule (especially posterior limb), brain stem and middle cerebellar peduncle. The patient developed various neurological abnormalities such as blurred vision, ataxic speech, gaze evoked horizontal nystagmus, bilateral pyramidal tract sign and limb ataxia after 8 years sniffing of thinner (mainly toluene). MRI examination revealed diffuse high intensity areas in cerebral white matter on T1 weighted image. On T2 weighted image, high intensity areas of deep cerebral white matter, internal capsule (especially posterior limb), cerebral peduncle, ventral pons and middle cerebellar peduncle were noted. Basal ganglia (caudate nucleus, lenticular nucleus and thalamus) were displayed as low intensity area on T2 weighted image. These high intensity areas of internal capsule, brain stem and middle cerebellar peduncle on T2 weighted image would be significant for understanding pyramidal tract sign and cerebellar sign of this case. On the basis of neuropathological descriptions of chronic toluene intoxication, these high intensity areas of T2 weighted image were presumed to be demyelinating lesions of the central nervous system.

A 10-year-old girl had complained of headache, vomiting and blurred vision for one month before admission to our hospital. Her neurological findings were normal, except that the examination of the fundi revealed papilledema. The cerebrospinal fluid pressure was elevated to 220 mmH2O. The brain MRI showed bilateral and approximately symmetrical hyperintense areas located in the thalamus. These disappeared on the repeated MRI, and her symptoms regressed spontaneously within a month. Her illness was diagnosed as benign intracranial hypertension because of the favorable clinical course. These reversible thalamic lesions might be due to circulatory insufficiency associated with intracranial hypertension.

A 29-year old female, in her second pregnancy, complained of headache, nausea, vomiting and left blurred vision. In spite of improvement of these symptoms in the second postpartum, she complained of recurrent symptoms in her third pregnancy. CT and MRI showed a pituitary adenoma with hematoma. It was totally removed using the transsphenoidal approach during pregnancy at 8 months. The histological examination revealed that the tumor was an acidophilic adenoma with a hemorrhagic change. A healthy baby was born at the full term after the operation. Our transsphenoidal operation during pregnancy was only the second such attempt reported in our collected literature. The management of the pituitary tumor during pregnancy is discussed.

A case of ganglioglioma associated with choked disc is reported. A 19-year-old girl was admitted to our hospital because of blurred vision. Neurologically, the patient had nothing but choked disc. The CT showed a large cystic mass with calcification in the left parieto-occipital lobe. The MRI revealed that the cyst was delineated by a membrane and that its dorsal side was solid, showing enhancement by Gd-DTPA. Cerebral angiography showed no tumor stain. Left parieto-temporo-occipital craniotomy was performed and the tumor was removed subtotally. Histopathological examination demonstrated the typical pattern of ganglioglioma. The most common symptom of ganglioglioma is convulsions. Symptoms of increased intracranial pressure have been reported sporadically in the literature. It was clinically noted that the cause of the increased intracranial pressure in this patient was enlargement of the cyst associated with ganglioglioma.

A 34-year-old woman was admitted for the chief complaints of headache and blurred vision. She had bilateral papilledema and slight increase in CSF pressure (175mmH2O) with normal visual acuity and field. Neurological and hormonal examination were normal except for over response of PRL and TSH to TRH test. The sella was enlarged and MRI and metrizamide CT demonstrated intrasellar CSF filling with remodeling of the pituitary gland. The patient was diagnosed as primary empty sella syndrome associated with benign intracranial hypertension. The complaints did not subside for six months. The patient was treated via the transsphenoidal approach. The dura mater of the floor of the sella was elevated by extradural balloon expansion filled with silicone, and subsequently the empty sella was obliterated. Her headache disappeared and amblyopic attack also improved. Obliteration of the empty sella with an extradural silicone balloon via the transsphenoidal approach seemed to have been effective for headache and visual complaints of primary empty sella syndrome which did not respond to medical therapy.

A 45-year-old man developed generalized convulsion and consciousness disturbance at age 43. An X-ray CT revealed hemorrhagic infarction in the left fronto-parieto-temporal area. A conventional angiography disclosed complete occlusion of the left cortical vein. In the chronic stage of the stroke, he had incomplete right quadrantopsia, a mild right hemiparesis and sensory aphasia. The patient has had partial somatosensory seizures since February 1990. Ictal EEG recordings showed epileptogenic discharges in the left parietal region. The seizures were adequately controlled with clonazepam. Since July 27, 1993, he has become aware of blurred vision in both eyes accompanied with headache and dizziness. On August 6, he was admitted to the hospital with right homonymons hemianopsia, sensory aphsia and tonic seizures in the right hand. Ictal EEG recordings demonstrated theta waves of the left parieto-occipital region and epileptogenic discharges in the left occipital region which consisted of spikes, sharp waves and spike-wave complexes. Single photon emission computed tomography (SEPCT) images obtained during seizures showed considerable hyperperfusion in the left occipital temporal lobes, while there was hypoperfusion in the left temporo-parietal area corresponding to the lesion of the old cerebral infarction. A T2-weighted MRI scan showed an abnormal high-intensity area in the left occipital lobe that suggested brain edema. After the admission, the patient was treated with additional anticonvulsant drugs. The tonic seizures in the right hand disappeared and right homonymous hemianopsia and sensory aphasia showed gradual improvement in the next four weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

A 35-year-old man with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) associated with acute bilateral optic neuritis is described. At age 33, he noticed a tingling sensation in his toes followed by weakness in the lower limbs. He was admitted to our hospital because he became unable to walk without support. His motor and sensory symptoms gradually resolved during 7 months admission only with physical rehabilitation. At age 35, in July 1988, he noticed a tingling sensation in his toes and fingers, which reached to the knees and elbows in October 1988, when he developed weakness in the lower limbs. Motor and sensory symptoms were almost stationary thereafter and in March 1989, he experienced bilateral blurred vision of acute onset without ocular pain. He was readmitted to our hospital in April 1989. The neurological examination revealed decreased visual acuity of both eyes without any abnormality of the optic disks, mild weakness on flexion and extension of toes, an absence of Achilles reflex, and distal impairment of pain and touch sensations in the upper limbs, and of pain, touch and vibration sensations in the lower limbs. After laboratory examinations, CSF protein was elevated (122 mg/dl), and sensory nerve conduction velocity of the right median nerve was decreased (37.1 m/sec). The sural nerve action potential was not elicited on electrical stimulation. Central scotoma was found in both eyes by the visual field examination. P100 latency was seen to be normal by repeated pattern-reversal visual evoked potential (VEP) studies. CT and MRI of the brain were unremarkable.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 64-year-old man with recurrent bouts of blurred vision who died after developing an abdominal mass. He was well until June of 1985 when he was 59-years-old when he had an acute onset of loss of vision in his right eye. He was treated by prednisolone with a complete remission. In August of 1986, he had another bout of blurring of vision in his left eye. Once he lost his left vision completely, from which he showed slow recovery. In January of 1987, he developed blurring of his right eye and loss of pain and touch sensation in his right leg. Since then he repeated loss of vision in his right or left eye five times, and he was admitted to our hospital in May of 1990. On admission, he was alert and oriented. General physical examination was unremarkable. Neurologic examination revealed bilateral optic nerve atrophy. He could not discriminate light or dark by either eye. Other cranial nerves were unremarkable. He could walk in a wide-base only with support; spasticity was noted in his left leg. Muscle strength was preserved. Deep reflexes were exaggerated in both legs with extensor plantar reflex bilaterally. Pain and touch sensation was decreased in the left leg by 30%, and vibration was diminished in both feet. Position sense was preserved. Routine blood counts and chemistries were unremarkable. Cranial MRI scans revealed multiple high-signal intensity lesions in both pontine bases, basal ganglia, thalami, and in the deep cerebral white matters. He was treated with oral prednisolone, plasmapheresis, lymphocytapheresis, and then immuran. His vision showed only slight recovery to discriminate light and dark. In October of 1990, slight weakness appeared in his both legs. In December of that year, he developed nausea, and a fiber colonoscopic study revealed a stenosis in the transverse colon. In March of 1991, he developed anemia and liver dysfunction. In July of that year, jaundice appeared, and his serum bilirubin was increased. In October, his leg weakness became more prominent, and his cranial CT scans at that time revealed a low density change in the right cerebellum in the right superior cerebellar artery territory; in addition, multiple low density spots were scattered to be seen in both cerebral hemispheres including the basal ganglia and thalamic areas with ventricular dilatation and cortical atrophy.(ABSTRACT TRUNCATED AT 400 WORDS)
