Sclerosteosis or Van Buchem's disease is a rare genetic craniotubular hyperostosis that becomes evident in early childhood and is associated with progressive involvement of the skull. The pathologic changes in the cranium noted on CT are described in three cases. Although the disease is incurable, CT is useful to display the morbid anatomy of the cranium before palliative surgery.

Ethyl alcohol: experimental agent for interventional therapy of neurovascular lesions.

Perfusion of absolute ethyl alcohol into the middle cerebral artery of six rhesus monkeys was performed using the Pevsner miniballoon catheter system. The animals were sacrificed by thoracotomy and intracardiac perfusion of a mixed aldehyde solution for fixation. Preliminary angiography and electron microscopy suggest absolute ethyl alcohol is a good neurovascular occlusive agent, and a possible replacement for isobutyl 2-cyanoacrylate in the treatment of angiomas and tumors.

Nonpulsatile exophthalmos in carotid-cavernous sinus fistula.

An unusual case of carotid artery-cavernous sinus fistula with pulseless exophthalmos is presented in a two and one-half year old child. Though exophthalmos and increased episcleral venous distention were present, the ophthalmic artery pressure was not significantly altered as determined by ocular pneumoplethysmography. Consequently there was no evidence of hypoxic sequelae which frequently occur with this arteriovenous shunt. The combined use of arteriography and ocular pneumoplethysmography is advocated for determining and characterizing the presence of significant intracranial arteriovenous disease.
