Local fibrinolysis in cerebral venous thrombosis.

Extensive cerebral venous sinus thrombosis may cause death or severe neurologic sequelae. A minimally responsive 10-year-old boy with thrombosis of the superior sagittal sinus, left transverse and left sigmoid sinus, torcular, vein of Galen, and straight sinus underwent fibrinolytic therapy with urokinase during transfemoral venous angiography. He improved dramatically during the procedure as antegrade venous flow was re-established.

Cerebral distribution of contrast medium during slow intracarotid infusion.

A prospective study was performed to evaluate in vivo the uniformity of cerebral distribution of iodinated contrast medium during slow intraarterial injection at rates used for chemotherapy installation in the internal carotid artery. We evaluated seven patients with primary intracranial neoplasms with routine film-screen angiography and with digital angiography during slow infusion. In six internal carotid artery injections the distribution of contrast material was identical during the late arterial phase of routine angiography and the digital study.

MR imaging of primary epidermoid tumors.

The magnetic resonance (MR) imaging characteristics of five primary intradural epidermoid tumors are described. At 0.35 T, the most consistent finding on spin echo imaging was a tumor signal intensity that differed from brain and CSF.
