A 19-year-old woman with aneurysmal bone cyst. A and B, Gadolinium-enhanced sagittal T1WI (A) and axial T2WI (B) show multiple fluid/fluid levels in a complex multicystic mass centered on the sphenoid bone, expanding the bone and filling the sphenoid sinus. C, Photomicrograph shows blood-filled cavernous channels at low-power magnification with (HE staining, original magnification ×4). D, Higher power photomicrograph shows spindle cells in the vessel walls, reactive bone formation, and multinucleated giant cells typical of these lesions (HE staining, original magnification ×40).
