Neurocutaneous spectrum of multiple endocrine neoplasia-1.

Multiple endocrine neoplasia type I or Wermer syndrome is characterized by primary hyperparathyroidism, enteropancreatic endocrine tumor, and a pituitary pathology. A 35-year-old male presented with visual field defects, hyperprolactinemia, and hypogonadism. He also had multiple infraumbilical skin-colored nodules. A syndromal association of Wermer syndrome was derived using the dermal, pituitary, parathyroid, and gastrointestinal hormonal manifestations of the tumor. The radiological and histological findings of lesion which underwent biopsy are discussed. The presence of collagenomas, lipomas, and hypopigmented macules in a patient with neuroendocrine symptoms should raise the suspicion of an underlying multiple endocrine neoplasia.

Persistent primitive hypoglossal artery associated with lower basilar artery aneurysm: diagnosis and clinical implications.

An elderly male was evaluated for subarachnoid hemorrhage and found to have a persistent primitive hypoglossal artery with its associated abnormal posterior fossa circulation and a lower basilar artery aneurysm. Angiography findings are described and are corroborated with computed tomography and magnetic resonance imaging. Its surgical and clinical relevance are discussed.
