Background And Objectives: Antiepileptic drugs (AEDs) are known to interfere with homocysteine metabolism. Hyperhomocysteinemia may be a risk factor associated in the long-term treatment with AEDs. Both genetic and non-genetic factors are responsible for hyperhomocysteinemia.

The hyperplasia could be physiologic which is usually reversible, or pathologic which varies in presentation from incidental to tumor like lesion with and without hormonal disturbance. Any pituitary cell is capable of undergoing hyperplasia in the presence of the right stimuli.

Case Description: A 32-year-old man presented with polyuria, polydipsia, anorexia, abdominal discomfort, and panhypopituitarism.
Patients And Methods: The clinical, radiological, surgical, and pathological findings of 16 children with a primary central nervous system (CNS) sarcoma are reported. There were 8 (50%) girls and 8 (50%) boys ranging in age from 4 months to 14 years (mean age 4.8 years).

The authors report, to the best of their knowledge, the first case of upper thoracic spinal cord herniation occurring after traumatic nerve root avulsion.

The case of a 30-year-old woman with clinical and biochemical evidence of Cushing disease (CD) is reported. A magnetic resonance image obtained preoperatively revealed asymmetrical inhomogeneity of the pituitary gland, which was suggestive of localized adenoma.

The authors report a case of brown tumor of the ethmoidal sinus, documenting its clinical, neuroimaging, and pathological features with long-term follow-up results, and review previous reports on this disorder.
View Article and Find Full Text PDFA 67-year-old man was found to have massive pituitary necrosis occupying approximately 85% of the anterior lobe after being supported with mechanical ventilation for 35 days. The findings were compatible with "respirator pituitary" found in mechanically ventilated patients. The lesions represent coagulative infarctions due to ischemia.
