There are a variety of imaging modalities for evaluation of peripheral nerves. Of these, ultrasonography (US) is often underused. There are several advantages of this imaging modality, including its cost-effectiveness, time-efficient assessment of long segments of peripheral nerves, ability to perform dynamic maneuvers, lack of contraindications, portability, and noninvasiveness. ⋯ Ideally, the neurosurgeon can use US as a diagnostic adjunct in the preoperative assessment of a patient with traumatic, neoplastic, infective, or compressive nerve injury. Perhaps its most unique use is in intraoperative surgical planning. In this article, a brief description of normal US nerve anatomy is presented followed by a description of the US appearance of peripheral nerve disease caused by trauma, tumor, infection, and entrapment.

Patients presenting with poor-grade aneurysmal subarachnoid hemorrhage (SAH) have commonly been reported to have a poor prognosis; however, several reports suggest a favorable outcome in a subgroup of patients. We analyzed our database to identify factors determining functional outcome after poor-grade SAH. ⋯ A favorable outcome was achieved in 24% of severely ill patients with poor-grade SAH. Therefore, treatment of patients with poor-grade SAH should not be omitted. Careful individualized decision making is necessary for each patient.
