Superficial subarachnoid cerebrospinal fluid space expansion after surgical drainage of chronic subdural hematoma.

Background: The present study examined the computed tomography (CT) findings after surgery and overnight drainage for chronic subdural hematoma (CSDH) to clear the significance of inner superficial subarachnoid CSF space and outer subdural hematoma cavity between the brain surface and the inner skull.

Methods: A total of 73 sides in 60 patients were evaluated. Head CT was performed on the day after surgery and overnight drainage (1st CT), within 3 weeks of surgery (2nd CT), and more than 3 weeks after surgery (3rd CT).

[Intracranial inflammatory pseudotumor resected after transcatheter embolization: a case report].

A 63-year-old man presented with an exceptionally rare case of intracranial inflammatory pseudotumor manifesting as speech and gait disturbance. Magnetic resonance imaging showed a left convexity mass with significant peritumoral edema. The mass was attached to the convexity dura and mimicked meningioma.

Critical classification of craniostomy for chronic subdural hematoma; safer technique for hematoma aspiration.

Chronic subdural hematoma (CSDH) is generally treated by twist drill, and one and two burr-hole craniostomy. We proposed new classification of the intraoperative condition of CSDH, and present a safer technique for aspiration of CSDH in one burr-hole surgery. The intraoperative condition of CSDH was classified according to the connections between the hematoma cavity and the extracranial space as follows.
