We report a case of pituitary apoplexy resulting in right internal carotid artery occlusion accompanied by hemiplegia and lethargy. A 43-yr-old man presented with a sudden onset of severe headache, visual disturbance and left hemiplegia. Investigations revealed a nodular mass, located in the sella and suprasellar portion and accompanied by compression of the optic chiasm. The mass compressed the bilateral cavernous sinuses, resulting in the obliteration of the cavernous portion of the right internal carotid artery. A border zone infarct in the right fronto-parietal region was found. Transsphenoidal tumor decompression following conservative therapy with fluid replacement and steroids was performed. Pathological examination revealed an almost completely infarcted pituitary adenoma. The patient's vision improved immediately after the decompression, and the motor weakness improved to grade IV(+) within six months after the operation. Pituitary apoplexy resulting in internal carotid artery occlusion is rare. However, clinicians should be aware of the possibility and the appropriate management of such an occurrence.

Botulinum toxin has become an important component of standard practice in the management of children with hypertonia (spasticity or dystonia). Following intramuscular injection, the neurotoxin causes a reversible neuromuscular blockade, creating both muscle weakness and a reduction in tone. Frequent goals of botulinum toxin injection include improving motor function, promoting longitudinal muscle growth and decreasing painful muscle spasms. The neuromuscular blockade lasts for three to six months on average. The clinical effect may last longer and the safety profile is excellent. Strong evidence, including randomized trials, exists for the efficacy of botulinum toxin in the management of lower and upper extremity tone in children. Common clinical indications include spastic equinus (toe walking), hip subluxation, upper extremity spasticity associated with hemiplegia or quadriplegia, and multilevel leg muscle injections in children with spastic diplegia.

Hemiplegic migraine is a condition associated with vascular alteration of the central nervous system and transient neurologic deficits. Permanent morphine-induced motor dysfunction has been reported after spinal ischemia. We report a persisting central neurological deficit after single-dose spinal administration of 400 microg of morphine in a patient with no previous neurological condition. Hemiplegic migraine was thought to be present when the patient emerged from anesthesia. Weakness in the left quadriceps and saddle anesthesia of the perineum and urinary retention of central origin remained present 3 yr later. Over the 3 postoperative years, the patient was admitted to a neurological unit 5 times because of acute headache associated with complete left-sided hemiplegia. These symptoms resolved within 24 h of onset. Hemiplegic migraine was thought to be the most likely diagnosis of these recurrent attacks. We hypothesize that the patient's persistent deficits were caused by a combination of spinal morphine and spinal cord vascular dysfunction associated with hemiplegic migraine.

Chorea that occurs as a result of a stroke is rare. We report a patient who developed hemiplegia following an acute hemorrhagic stroke in the left cerebral peduncle and subthalamus; although he had recovered gradually from the severe limb weakness, monochorea occurred 6 months later. Pallidotomy eliminated this symptom and we found it is a safe treatment for medically intractable post-stroke chorea after hemiplegia has resolved.

Alternating hemiplegia of childhood is a neurological disorder characterized by episodes of hemiplegia, various non-epileptic paroxysmal events and global neurological impairment. Characterization of the evolution and outcome into adulthood has not been sufficiently investigated. The goal of this study was to elucidate the natural history of alternating hemiplegia within a large cohort of 157 patients, as part of the European Network for Research on Alternating Hemiplegia project. A questionnaire was formulated to determine the severity of both paroxysmal and global neurological impairment and address progression of the disorder by allocating data to specific age epochs up to and over 24 years of age. Patients in early age groups were consistently present in subsequent later age groups and for each patient, data were collected for each corresponding age epoch. The study was based on predominantly retrospective and, for a period of 2 years, prospective data. At inclusion, patients were aged from 9 months to 52 years. The median age at diagnosis was 20 months. All patients experienced hemiplegic attacks; 86.5% reported episodes of bilateral weakness, 88% dystonic attacks, 53% epileptic seizures, 72% developed chorea and/or dystonia and 92% mental retardation. When data over the course of the illness were examined for the whole cohort, the severity of symptoms did not appear to change, with the exception of abnormal ocular movements and hypotonia that regressed, but did not disappear into adulthood (from 86 to 36% and 76 to 36%, respectively). No statistically significant correlation between a history of severe paroxysmal hemiplegic/dystonic episodes and a worse neurological outcome was identified. Seven patients died, some of whom experienced severe plegic attacks or epileptic seizures at the time of death. History of severe plegic/dystonic attacks was not found to be an aggravating factor for deceased patients. Our results provide evidence that the natural history of alternating hemiplegia is highly variable and unpredictable for individual patients. However, we did not find evidence to support a steadily progressive and degenerative course of the disorder when patients were analysed as a group. For a minority of patients, a risk of sudden death was associated with more severe neurological impairment. The European Network for Research on Alternating Hemiplegia Registry, validated by our study, includes all major neurological signs and symptoms of alternating hemiplegia and may thus be used as a precedent for the progressive inclusion and follow-up of patients as well as a reference for genetic studies and treatment trials.

Scoliosis is an important cause of disability in childhood, due to its incidence and limitation on ability. In neurodevelopmental disabilities, scoliosis worsens the already limited functional capacities of the child and can thwart abilities partially recovered through rehabilitation. In celebral palsied children (CP), scoliosis is considered a consequence of damage to the central nervous system or a complication of a peripheral impairment, in particular, through obliquity of pelvis, of the unilateral dislocation of hip. In order to explain the scoliosis of central origin, primitive and pathological reflexes, reactions or automatisms must be taken into account, especially the asymmetrical ones. This contradicts the absence of scoliosis in hemiplegia. On the contrary, symmetrical patterns should act as protective factors. However, the greater incidence of scoliosis in tetraplegia than in dipegia does not confirm this idea. Scoliosis is secondary when it is linked to an unilateral hip dislocation for side of convexity, proximity, measure and timing sequence. In childhood neuromuscular diseases (NMD), scoliosis is the unavoidable consequence of muscle weakness. The only protective factor may be muscle stiffness in case of fibrotic degeneration. The main curve is reducible for longer periods, while the less reducible secondary one at cervical level can limit the correction possibilities, due to the need to keep the head aliened. In spina bifida (SB) children, lesional and supralesional scoliosis can be present. In the former, the malformative ones directly derive from the vertebrae involved in the myelomeningocele and the secondary ones develop from the unilateral hip dislocation similar to CP, or from muscular imbalance (a typical feature of SB, especially for lower lumbar levels) or from primitive skeletal malformations of pelvic girdle or lower limbs. The acquired ones are caused by muscle weakness as in NMD. In the supralesional scoliosis, the curve is the consequence of an impairment in neurological structures especially of ponto-cerebellar carrefour or of an acquired tethered cord and may affect any segment of spinal column, also above the primitive lesion level. The scoliosis in neurodevelopmental disabilities can be treated conservatively with corsets and postural systems, with limited results. or through a surgical approach, often made difficult due to the multiple impairments present in the same patient.

An 81-year-old man had sudden-onset dysarthria and weakness in the right leg, and was admitted to our hospital in July 2009. Neurological examination showed right leg monoparesis, sensory disturbance on the right limbs, dysarthria, and decreased deep tendon reflexes. Brain MRI revealed an acute lacunar infarction in the right corona radiata and an old lacunar infarction in the left centrum semiovale, which occurred 4 years before. MR tractography disclosed impaired motor fibers in the right corona radiata, and transcranial magnetic stimulation (TMS) suggested diminished innervation from the bilateral cerebral cortices to the right leg. These results collectively indicated that reorganization of the pyramidal fibers were responsible for the monoparesis ipsilateral to the lacunar infarction, although anomalous pyramidal fibers with ipsilateral innervation were responsible for ipsilateral hemiplegia a previous study.

Excessive pelvic rotation in the transverse plane is common in patients with cerebral palsy. Knowing the underlying reasons is important for clinical decision making, since changes in pelvic retraction might have an effect on internally rotated gait. We hypothesized that the contralateral leg contributes considerably to pelvic rotation on the retracted side. Therefore the aim of this study is to calculate predictors for pelvic retraction using both, parameters from the retracted and from the contralateral protracted side. Thirty-two children with diplegia and 18 children with hemiplegia were examined by three-dimensional gait analysis followed by a clinical examination protocol. Stepwise multilinear regression of the response value mean pelvic retraction during stance phase was performed on 10 potential predictors of dynamic gait data and 10 corresponding predictors of clinical data of the retracted and the contralateral protracted side. Gait analysis revealed ankle push-off energy on the protracted side as the best predictors in hemiplegic patients explaining 59% of the variance in pelvic retraction. In diplegic patients external hip rotation of the protracted side was most accurate in predicting pelvic retraction (27%). Best clinical predictors for hemiplegic patients were ankle dorsiflexion on the retracted side (46%) and for diplegic patients it was the knee extension strength on the protracted side together with hip rotation on the retracted side (36%). In hemiplegic patients ankle push-off energy of the contralateral side is a significant compensation mechanism that might cause increased pelvic retraction to compensate for the weakness of the involved side. In diplegic patients prediction of pelvic retraction was only moderate and requires further investigation.

Epilepsia partialis continua (EPC) is clinically defined as a syndrome of continuous focal jerking of a body part, usually a distal limb, occurring over hours, days, or even years. It is considered the status epilepticus equivalent of simple partial motor seizures. A 48-year-old right-handed man with a history of traumatic intracranial hemorrhage was admitted for right-sided hemiplegia and drowsiness after complex partial status epilepticus. An EEG showed periodic lateralized epileptiform discharges over the left hemisphere. Brain MRI revealed extensive multifocal encephalomalaciac changes in the left temporo-parieto-occpital lobe and both frontal lobes with some hemorrhagic residual change. After administration of a loading dose of intravenous phenytoin, his mental status returned to normal. However, his weakness only partially improved. [(18)F]Fluorodeoxyglucose PET (FDG-PET) demonstrated severe hypometabolism in the left cerebral hemisphere, including the basal ganglia and thalamus, with cerebellar diaschisis. At the 3-month follow-up, he complained of symptoms of alien hand phenomenon. Follow-up MRI revealed more extensive encephalomalaciac changes in previously noted regions with thinning of the posterior end of the body of the corpus callosum. Moreover, FDG-PET demonstrated persistent severe hypometabolism over the left cerebral hemisphere. We suggest that the alien hand phenomenon was a result of thinning of the corpus callosum related to EPC.
