Nasal glioma.

Six cases of nasal gliomas, which are rare ectopic rests of neural tissue found at the root of the nose, are presented. It is important to distinguish nasal tumors from basofrontal encephaloceles to avoid inadvertent exposure of the brain during the surgical removal of mass lesions. Because of their related embryologic origins, the distinction between nasal gliomas and basofrontal encephaloceles may not be clear clinically. Nasal gliomas may be treated by several surgical specialties, and only a proper awareness of their relatonship to encephaloceles can assure the selection of a flexible and adequate surgical approach. This paper emphasizes the salient clinical characteristics of nasal gliomas, their clinical distinction form and embryologic relationship to encephaloceles, and the options for treatment.

Intracranial aneurysm and hemorrhage following skull caliper traction. Review of skull traction complications.

Serious complications of caliper skull traction for fracture-dislocations of the cervical spine are so rare that they are not discussed in most standard textbooks. A fusiform intracranial aneurysm which followed the placement of skull tongs is reported. Subsequent aneurysmal rupture produced an intracerbral hematoma requiring drainage. The literature recording the complications of skull caliper traction is reviewed and the indications for skull traction and the need for scrupulous surgical technique are emphasized.

Fusiform basilar aneurysm simulating carotid transient ischemic attacks.

Fusiform aneurysms of the basilar artery are extremely unusual. Most show signs of a posterior fossa mass. One case is reported which presented with recurrent transient ischemic attacks suggesting carotid vascular disease. Failure of an appropriate endarterectomy to relieve the symptoms, and later brain stem infarction, led to the correct diagnosis. Whenever recurrent or new symptoms appear following carotid vascular surgery, other diagnoses must be considered.

Intra-arterial nitroprusside treatment of acute experimental vasospasm.

The effect of intra-arterial sodium nitroprusside infusions on acute experimental basilar artery spasm was studied in dogs. Vasospasm produced by subarachnoid hemorrhage at normal intracranial pressure was partially relieved by nitroprusside. When given by the intra-arterial route, 15 times the recommended maximum intravenous does can be infused without significant hypotension or elevation in intracranial pressure.
