Aneurysmal bone cyst of the spine in children. MRI imaging at 0.5 tesla.

Two patients with aneurysmal bone cysts of the spine demonstrate striking similarities when examined with magnetic resonance imaging (MRI), while the plain radiographs and images on computed tomography (CT) are quite different. Gadolinium DTPA enhanced T1W images were especially helpful in the definition of the lesion by showing enhancement of the septations of the aneurysmal bone cysts. The septations represent the fibrous walls inherent to these lesions.
