Schizencephaly: a clinical study and review.

Schizencephaly is a rare malformation in which symmetrical portions of the cerebral mantle fail to develop. It should be differentiated by angiography and pneumography from the porencephalies that follow destructive lesions and from the prognostically more favorable subdural hematomas and effusions. If the diagnosis of this anomaly can be firmly established short of surgical exploration, operation or further treatment of any kind is not, in the authors opinion, warranted.

Prolactin-producing pituitary adenomas.

Eight patients with amenorrhea, galactorrhea, and hyperprolactinemia underwent excision of pituitary adenomas by means of a microsurgical procedure that used a transsphenoidal approach. Prolactin values returned to normal in five of the patients and were significantly lower in three. Five patients resumed their menses. Two became pregnant. All eight patients had used oral contraceptives. The association of oral contraceptives and prolactin-producing pituitary adenomas is discussed.

Vertebral artery aneurysm--a unique hazard of head banging by heavy metal rockers. Case report.

A 15-year-old drummer in a neighborhood rock music band suffered a traumatic true aneurysm of the cervical vertebral artery from violent head and neck motion. He underwent excision of the aneurysm after distal and proximal ligation of the artery. He is neurologically normal 1 year after surgery. The mechanisms of injury caused by extremes of cervical motion, as well as 5 previously reported cases of extracranial vertebral artery aneurysm from closed trauma, are discussed. Excision of vertebral artery aneurysms in patients with emboli from a mural thrombus is recommended. The consequences of vertebral artery ligation and the indications for distal reconstruction are discussed.

The infratentorial-supracerebellar exposure of tumors in the pineal area.

Nine pineal area lesions were operated upon by the infratentorial-supracerebellar approach. There was one operative death and one death due to disseminated germinoma recurrence 2 1/2 years postoperatively. The remaining seven patients have shown no sign of recurrence and are neurologically normal. The surgical method that has evolved through these nine cases is discussed. The infratentorial-supracebebellar exposure is an excellent one for lesions in the region of the pineal gland, posterior 3rd ventricle, and superior cerebellar vermis. Access is less hampered by the major tributaries of the vein of Galen than with the supratentorial operations. This approach is also a useful extension of the standard posterior fossa exploration when dealing with primarily subtentorial lesions that involve the dorsal midbrain or herniate upward.

Bilateral optic canal meningiomas: a case report.

In the case presented, bilateral optic canal meningiomas produced binocular visual loss. Correct diagnosis was delayed because of inadequate and misinterpreted radiological studies. Careful radiological and surgical examination of the planum sphenoidale later suggested this as the source of both canalicular masses. The pertinent aspects of this case are reviewed in relation to information from similar cases reported previously. In the future, increased clinical suspicion and more accurate neuroradiological studies should improve the detection and afford earlier surgical treatment of meningiomas of the optic canal.
