Capillary Hemangioma in the Superior Sagittal Sinus as a Rare Cause of Intracranial Hypertension in a Child: Case Report

Abstract

A tumor growing into a venous sinus is a rare cause of venous outflow impairment and may generate the clinical signs of idiopathic intracranial hypertension. This case emphasizes the importance of multiple complementary imaging modalities and the efficacy of a direct surgical approach, which allowed resolution of symptoms.

Durable response of intracranial cellular hemangioma to bevacizumab and temozolomide

“…6 Intracranial hemangiomas are extremely rare; only 20 biopsy-proven cases were found in the literature. 1,2,5,8,10,11,13,17,18,[20][21][22][23][24] With the exception of 4 cases, 11,20,23 the reported primary mode of treatment was neurosurgical resection, of which complete resection was achieved in 12 of the 16 cases. In the other 4 cases, 13,17 only subtotal resection was possible, and additional surgery or radiotherapy was needed to achieve tumor control.…”

Surgical management of intracranial capillary hemangiomas in children: report of 2 cases

“…Brotchi et al have described the case of a child presenting with elevated ICP secondary to an ICH that caused sagittal sinus obstruction. 3 Other authors have reported children presenting with signs and symptoms of elevated ICP secondary to the shear size of the ICH itself. 4,5,19 One infant died of a subarachnoid hemorrhage in association with a skull base ICH fed by the anterior choroidal artery.…”
