Third nerve paresis caused by vascular compression by the posterior communicating artery.

Objective And Importance: Third nerve paresis frequently occurs because of external compression by an internal carotid-posterior communicating artery aneurysm. We report 1 case of third nerve palsy because of direct vascular compression by the posterior communicating artery.

Clinical Presentation: A 69-year-old man presented to the hospital with the sudden onset of left third nerve palsy and a history of chronic headaches.

Cocaine-induced intratumoral hemorrhage: case report and review of the literature.

A unique case is described of a 28-year-old man who had seizures and a hemorrhage within a previously unsuspected cerebellopontine angle schwannoma within minutes of nasally inhaling cocaine. A review of the literature on cocaine-induced seizures and cocaine-induced cerebral hemorrhage is also given.

One-stage construction of giant experimental aneurysms in dogs.

In an attempt to find safe and effective methods of treating giant intracranial aneurysms, we have developed a one-step construction of giant experimental aneurysms in dogs with a yield of 100% patency of the parent artery and the experimental aneurysm without intraaneurysmal thrombus. Giant aneurysms were produced in the right thrombus. Giant aneurysms were produced in the right common carotid artery of nine mongrel dogs.

Superior hypophyseal artery aneurysm. Report of two cases.

Two cases of saccular intracranial aneurysms arising from the superior hypophyseal artery take-off from the internal carotid artery are presented. The angiographic findings and technical details of the operative approach are discussed. Particular attention is focused on the use of fenestrated angled clips.
