✓ Diffuse lymphocytic infiltration of the adenohypophysis occurring in temporal relation to pregnancy was found in two patients, each of whom had an intasellar mass with suprasellar extension that caused compression of the optic chiasm. The pathology and etiology of this lesion is discussed. This entity should be considered when evaluating patients with a pituitary mass lesion that presents in temporal association to pregnancy, particularly if there is evidence of hypopituitarism rather than a hypersecreting, endocrineactive adenoma.

✓ Hypertrophic interstitial neuropathy (HIN) of the trigeminal nerve was observed in a patient with trigeminal neuralgia who had no other neurological abnormalities. Pathological documentation confirmed focal HIN. No similar histologically documented case of isolated trigeminal nerve involvement by HIN has been reported previously.

✓ Over a 1-year period, a 60-year-old woman had nine episodes of transient weakness, clumsiness, and hypesthesia of the right upper extremity. Angiography revealed normal extracranial vessels and a left middle cerebral artery aneurysm. The aneurysmal sac, removed at operation, had an organized thrombus, which was believed to be the cause of the transient ischemic attacks. Postoperatively, the patient has remained free of neurological symptoms.

✓ A case is described in which a metastatic ependymoma of the cauda equina recurred after prolonged remission. Similarities to five previously reported cases are discussed, with emphasis on the mode of metastasis. Factors most closely associated with distant metastases include early onset, numerous local operations, long survival, and massive local recurrence at the time of distant metastases.
