The relationship of the anterior inferior cerebellar artery (AICA) to the facial (7th) and vestibulocochlear (8th) nerves was studied using 3x to 20x magnification in 50 cerebellopontine angles (CPAs) from 25 adult cadavers. The AICA originated from the basilar artery as a single (72% of the CPAs), duplicate (26%), or triplicate (2%) artery. Each of the 50 CPAs had one or more arterial trunks that coursed in close proximity to the 7th and 8th cranial nerves and thus were said to be nerve-related. ⋯ The internal auditory and recurrent perforating arteries arose most commonly from the premeatal segment, and the subarcuate artery arose most commonly from the postmeatal segment. There were one to four internal auditory arteries per CPA, zero to three recurrent perforating arteries, and zero or one subarcuate artery. The effects of occlusion of the nerve-related arteries and their involvement in conditions treated by neurosurgeons are reviewed.

One of the most catastrophic complications of intracranial surgery is infection. These infections present frequently as postoperative fever and a change in sensorium. ⋯ The phenytoin sensitivity syndrome is reviewed with emphasis on the fact that all components of the syndrome are not always present initially. The clinical significance of the presentation of phenytoin hypersensitivity as postoperative fever is discussed.

Acute central cervical spinal cord syndrome caused by missile injury: case report and brief review of the syndrome.
The authors present the second reported case of acute central cervical spinal cord syndrome caused by a missile injury. A low caliber, low velocity bullet penetrated the spinal cord posteroanteriorly at C-2, C-3 in the midline, producing quadriplegia and respiratory failure. ⋯ Injury to the central cervical spinal cord seems to produce a constant syndrome irrespective of the specific nature of the primary injury. The literature on this syndrome is briefly reviewed.
