The imaging sequences also showed an intraspinal paramedullary partially thrombosed aneurysm, compressing the spinal cord at T12 level, and several flow voids superior and inferior to the aneursym which indicated a spinal arteriovenous malformation ( figure 1 ). [...]intracranial aneurysms are mostly of congenital origin. [...]these lesions may be classified as flow-directed aneurysms. 1-3 These aneurysms may occur at all segments of the spinal artery, except bifurcations and generally fusiform type rather than sacculary. 1 ASAA is usually small in calibre, and giant aneurysms are very rare.
