Review Case ReportsArteriovenous malformation associated with a large cyst--case report.
A 37-year-old male presented with an arteriovenous malformation in the left temporal lobe associated with a large cyst. The cyst was drained and the nidus completely excised. The histological findings suggest that repeated subclinical hemorrhages from neovascular channels of the cyst membrane was responsible for the growth of the cyst.

Case ReportsAcute revascularization for bihemispheric anterior cerebral artery thrombosis--case report.
A 65-year-old male presented with rapidly progressive paraparesis and akinetic mutism due to occlusion of the bihemispheric anterior cerebral artery (ACA). He was treated by intra-arterial thrombolytic therapy but reocclusion of the arteriosclerotic lesion occurred. Bilateral superficial temporal artery (STA)-ACA anastomoses achieved lasting neurological improvement. Bilateral STA-ACA anastomoses are quite effective to prevent ischemia of the bilateral ACA territories.

Case Reports Clinical TrialIntraoperative spinal sonography in the cervical anterior approach.
Intraoperative spinal sonography was used during cervical anterior approach procedures for cervical discectomy and osteophytectomy to demonstrate spinal pulsation, the protruded disc or osteophyte, the anterior subarachnoid space, and the spinal cord. Spinal pulsation was recognized in some cases before removal of the disc but the anterior subarachnoid space and spinal cord could not be observed. However, the latter were more clearly observed during removal of the disc and could be seen after total removal of the disc and osteophyte. This method allows confirmation of decompression and pulsation of the spinal cord without cutting and removal of the posterior longitudinal ligament.

Postoperative chronic subdural hematoma following craniotomy--four case reports.
Postoperative chronic subdural hematoma (CSH) following craniotomy developed in only four of 372 patients undergoing craniotomy for aneurysm surgery (1 patient) and brain tumor surgery (3 patients) between April, 1991 and November, 1993, an incidence of only 1.1%. There were three males and one female, aged from 32 to 66 years (mean 56 yrs). The period between craniotomy and development of CSH ranged from 3 to 5 months (mean 4.3 mos). ⋯ Early postoperative computed tomographic scans found subdural fluid collection in all patients. Magnetic resonance images showed linear meningeal enhancement in all patients. Postoperative CSH may be caused by mixture of blood in subdural cerebrospinal fluid collection which persists due to reduced brain elasticity and wide subarachnoid membrane opening resulting in neomembrane formation and finally development of hematoma.

Case ReportsLumbar adhesive arachnoiditis following attempted epidural anesthesia--case report.
A 30-year-old female experienced a sudden sharp pain radiating down to the left leg from the lower back at epidural intubation for anesthesia at childbirth. She continued to complain of pain in the left leg afterwards. ⋯ Her symptoms disappeared after surgery, but soon recurred, being less severe and responsive to anti-inflammatory agents. Lumbar adhesive arachnoiditis should be considered for differential diagnosis in patients presenting with back and leg pain syndrome.
