1/20. trihexyphenidyl in posthemorrhagic dystonia: motor and language effects.

    trihexyphenidyl has been found to be an effective treatment for dystonic movement disorders, improving gross motor function in patients with axial and torsional dystonia, tremors, and myoclonus. In this report, improvements in fine motor control, language, and oral motor skills are described with trihexyphenidyl in an 8-year-old female who developed dystonia after spontaneous bilateral putamenal hemorrhages. No adverse side effects occurred. The mechanism of action of trihexyphenidyl is believed to be in the basal ganglia where it inhibits muscarinic cholinergic receptors and increases the turnover of dopamine.

2/20. August 2000: Two cases with necrosis and hemorrhage in the putamen and white matter.

    The August COM: Acute methanol poisoning is an uncommon, but well-recognized, cause of central nervous system injury. We present two autopsy cases showing the classic neuropathologic injuries in acute methanol poisoning: putamen and white matter necrosis and hemorrhage. In Case 1, putamen hemorrhages were striking; white matter pathology predominated in Case 2. The precise mechanism of methanol toxicity is unclear. Direct toxicity of metabolites, particularly formic acid, as well as ischemic injury and acidosis likely play a role. methanol is readily available in many commercial products, and may be ingested accidentally or intentionally.

3/20. Unusual CT and MRI appearance of carbon monoxide poisoning.

    Unilateral low attenuation areas within the right putamen, globus pallidus and thalamus were observed on CT in a patient after exposure to carbon monoxide. A transient bilateral appearance was found on subsequent CT examinations. Hemorrhagic infarction of the right putamen, and ischemic lesions in both thalami were visualized on MRI 2 weeks later.

4/20. pheochromocytoma of the urinary bladder revealed with cerebral hemorrhage.

    The case was a 51-year-old man, who has been undergoing treatment with oral medication for hypertension for three years. The patient was admitted to the author's clinic for hemorrhage in the left putamen. He was diagnosed as having primary pheochromocytoma of the bladder from such symptoms as paroxysmal blood pressure elevation after urination, mild increase in catecholamine levels before and after urination, and from the results of 131I-MIBG scintigraphy, and cystoscopy, and underwent excision of the bladder tumor. Upon endocrinological examination, only mild increases in catecholamine levels were found. Therefore, constant monitoring of blood pressure and 131I-MIBG scintigraphy were useful for a definitive diagnose.

5/20. Male prolactinoma with pituitary apoplexy concomitant with intracerebral hemorrhage--case report.

    A 56-year-old male presented with a prolactin-secreting pituitary adenoma who suffered pituitary apoplexy associated with intracerebral hemorrhage of the caudate head and putamen. The centers of both the intratumoral hematoma and intracerebral hemorrhage appeared as hyperintense on T1-weighted and T2-weighted magnetic resonance imaging, indicating the subacute stage and probably similar timing of onset. The tumor was treated surgically 6 weeks after the onset. The causative factor for the apoplexy remains unclear.

6/20. Bilateral striatal necrosis in hemolytic-uremic syndrome.

    A 41-year old resident of a nursing home presented with bloody diarrhea, and subsequently developed hemolytic-uremic syndrome. E. coli serotype O157:H7 was isolated from the stool culture. At autopsy she was found to have bilateral symmetrical striatal necrosis involving mainly the putamen and lateral globus pallidus. The main microscopic findings consisted of coagulative necrosis, endothelial damage and microthrombosis. Scattered microscopic lesions of similar appearances were noted in the parietal cortex, external capsule and fornix. This case is of particular interest because of the rarity of bilateral striatal necrosis in hemolytic-uremic syndrome and the recent experimental data which implicate E. coli endotoxin in the pathogenesis of cerebral lesions in this syndrome.

7/20. Left hemisphere intracerebral hemorrhages studied by ( (F-18)-fluorodeoxyglucose PET.

    We used PET to study patients with intracerebral hemorrhages in the left hemisphere. Three anatomic and physiologic patterns were observed. patients 1 and 2 had midputamen hemorrhages with diffuse left less than right hemispheric metabolic asymmetry most prominent in temporal and parietal regions. patients 3 and 4 had posterior putamen-insula-temporal hemorrhages with left less than right metabolic asymmetry in temporoparietal cortex and thalamus. patients 5, 6, and 7 had smaller posterior hemorrhages. Left cortical metabolism was little affected in these three cases. Persistent aphasia was associated with severe metabolic left less than right asymmetry in posterior middle temporal regions.

8/20. Bilateral intracerebral haemorrhage presenting with supranuclear ophthalmoplegia, bradykinesia and rigidity.

    A 70 year old man recovered from a left putamenal haemorrhage in 1984 with a residual mild right hemiparesis. In 1985 he presented following the sudden onset of inability to stand. The clinical findings of supranuclear ophthalmoplegia, bradykinesia and rigidity resembled those of progressive supranuclear palsy. CT scan revealed a recent haemorrhage deep in the right hemisphere white matter in addition to a low density change in the left basal ganglia reflecting the site of previous haemorrhage. The patient's course was uncomplicated and the ophthalmoplegia resolved. Bradykinesia and rigidity persist. This case illustrates an unusual clinical presentation of bilateral intracerebral haemorrhage with supranuclear ophthalmoplegia, bradykinesia and rigidity.

9/20. Hypertensive putaminal hemorrhage presenting with hemichorea.

    A progressive motor deficit primarily manifested by hemichorea developed in a 42-year-old hypertensive man. CT scan demonstrated contralateral putaminal hemorrhage. The patient's course was benign. Previous cases of acute hemichorea familiar to use and documented by CT scans have involved nonhemorrhagic lesions of either the putamen or caudate.

10/20. aphasia after left hemispheric intracerebral hemorrhage.

    The function of subcortical nuclear structures in language is uncertain, and language disorders after injury to these structures are described incompletely. We report 15 patients with left putaminal or thalamic hemorrhage, describe the range of language and behavioral disorders produced, and review the potential mechanisms of these disorders. Clinicoanatomic correlations revealed no definite differences between aphasia after hemorrhage in putamen or in thalamus.
