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.
