Intracranial tuberculomas generally present as either solitary or multiple lesions in the brain parenchyma. They are characterized by a ring-enhancing area on either computerized tomography scans or magnetic resonance images. A case is presented in which an intracranial tuberculoma was dural based and had an appearance similar to an en plaque meningioma.

A patient with an arteriovenous malformation experienced a severe neurologic deficit during preoperative particulate embolization with Silastic spheres. Angiography and radiography showed that one sphere had become lodged in a normal branch of the middle cerebral artery. After several unsuccessful attempts at dislodgment, a Tracker catheter system was advanced directly to the site of the sphere, and the sphere was successfully dislodged. The neurologic deficit cleared immediately, and the sphere was redirected to an artery feeding the malformation.
