The problems associated with the identification of the source of bleeding in multiple intracranial aneurysms are discussed, and the contribution towards diagnosis of each method of examination and investigation are evaluated, special emphasis is laid on the use of CAT scanning and electroencephalography as additional aids in localisation.

A new instrument for stereotactic evacuation of intracerebral haematomas is presented, as well as preliminary clinical experiences. A combined screw-and-suction technique makes possible the evacuation of even densely coagulated clots. The principle for a limited removal of a hemorrhagic mass in the brain is discussed.

A case of post-traumatic, contre-coup Wernicke's aphasia resulting from left posterior temporal hemorrhagic contusion localized by angiography and CAT scan is reported.

Five cases in which the Klippel-Trenaunay-Weber syndrome was associated with a spinal cord arteriovenous malformation are reported: they formed part of a series of 150 spinal arteriovenous malformations. Hypertrophic lesions, dilated arteries and varicose veins were present in every case, but cutaneous angiomatosis was found in only two. In each case, there was an intramedullary AVM. The relationship of the Klippel-Trenaunay-Weber syndrome to the regional angiomatous phacomatoses is discussed.

Five hundred patients with trigeminal pain underwent percutaneous thermocoagulation of the Gasserian ganglion. Of these 416 had classical trigeminal neuralgia, 49 had atypical facial pain and 35 had symptomatic trigeminal neuralgia. ⋯ These patients have been followed for from eight to 57 months. The beneficial results of this operation and the complications are presented.
