Non-Portuguese motor system degeneration in a black family
ABSTRACT
Autosomal dominant motor system degeneration has been described primarily in Portuguese families from the Azorean Islands. The symptoms include various combinations of ataxia, pyramidal and extrapyramidal signs, appendicular dystonias, tics, ophthalmoplegias, and peripheral neuropathies with amyotrophy. One non Portuguese, non‐Azorean black family has been described previously; this report describes a second such family affected by autosomal dominant motor system degeneration.

Solitary metastasis of systemic malignant lymphoma to the cerebellopontine angle
ABSTRACT
Systemic malignant lymphoma rarely produces solitary metastasis to the brain. We report such a case in the cerebellopontine (CP) angle mimicking an acoustic neurinoma. CT scan showed a large, round mass in the CP angle which enhanced homogeneously following contrast infusion. The internal auditory meatus appeared to be eroded. The clinical, radiological, and pathological findings are presented.
Reversed hemispheric organization in a left-hander
Abstract:
For left-handers, cognitive functions are organized in the brain similarly to right-handers or they are more diffusely represented. In this study, we report a left-handed patient with a focal right temporal-parietal lesion who evidenced a lasting Wernicke's aphasia and visual-spatial functioning typical of a right-hander with left-hemisphere in involvement. The patient's performance on other tasks (e.g. praxis, singing) as well as observed behavioral changes also resembled those of a right-hander with left-hemisphere compromise. This case suggests that it is possible for cognitive functions to be inversely represented in the two hemispheres.
