Malignant rhabdoid tumor of the central nervous system with subarachnoid dissemination.

A case of primary central nervous system malignant rhabdoid tumor is presented. Clinical, radiological, and histopathological findings are described in detail. Because of a relatively long clinical course after presentation, it was possible to assess the clinical and radiological response to different treatment modalities: surgery, chemotherapy, and radiotherapy. Despite the complete clinical and radiological response that was achieved after subtotal excision, two cycles of chemotherapy, and high-dose radiotherapy, the tumor recurred within 4 months of completion of the treatment, with wide subarachnoid dissemination. Radiotherapy treatment of whole cranial axis is recommended.

Hereditary motor sensory neuropathy type I presenting as scapuloperoneal atrophy (Davidenkow syndrome) electrophysiological and pathological studies.

A 14 year old boy with scapuloperoneal muscular atrophy, pes cavus, areflexia and distal sensory loss (Davidenkow syndrome) is described. Nerve conduction velocities were diminished. Sural nerve biopsy demonstrated a reduction in the number of myelinated fibers and early "onion-bulb" formation. These observations support the hypothesis that the scapuloperoneal amyotrophy associated with distal sensory loss may represent a variant of type I hereditary motor sensory neuropathy.

Thyroxine-induced petit mal status epilepticus.

Petit mal status epilepticus was induced by high doses of thyroxine, confirming experimental evidence that thyroxine may lower the seizure threshold. This is another hazard of rapidly correcting the hypothyroid state.

Leigh's disease with clinical manifestations of Cornelia de Lange syndrome.

Leigh's disease was found postmortem in a 5-year-old girl who was diagnosed clinically as Cornelia de Lange syndrome at age 1 year. The child's neurological status began to deteriorate rapidly at age 4.5 years and she died suddenly 6 months later. Postmortem examination of the brain revealed bilateral necrosis of the hypothalamus, subthalamic nuclei, midbrain, pons, and medulla. Previous studies have linked Cornelia de Lange syndrome to hypothalamic lesions. This case demonstrates that Leigh's disease, which also damages the hypothalamus, could present with phenotypic features of Cornelia de Lange syndrome.
