Diagnosis: Cavernous hemangioma
Cavernous hemangiomas are focal, mixed signal lesions usually found in the deep or sub-cortical white matter or basal ganglia with magnetic susceptibility due to calcification or chronic hemorrhagic products which "bloom" on the second echo or GRE weighted sequence. Most are solitary and supratentorial, and usually present in young adulthood. They may be associated with venous angiomas and there is a familial, multiple form. The symptoms may include headache, focal neurologic deficit or seizures. They are not visible on angiography and consist of dilated venous sinusoids without normal intervening neural tissue. The differential is limited due to the stability and classic appearance of the lesion. If there were no comparison study, even though the appearace is typical, follow-up to rule out underlying neoplasm is indicated. Related Cases
