case_images: an oval intradural mass lesion is revealed on magnetic resonance imaging of the lumbar spine at the T12-L1 level, with a low signal on T1 W and a high signal on T2 W images marked by short arrows. There is obvious compression of conus medullaris by the mentioned mass.

case_images: MRI of the lumbosacral spine showed an intradural extramedullary enhancing mass lesion measuring 16x11 mm at the T12-L1 level, causing severe cord compression (Fig. 1, Fig. 2).
case_images: Dilated blood-filled vessels lined by flattened endothelium are shown in the microscopic examination of resected mass, marked by short arrows. (H&E stained, x400).

case_images: Microscopic examination revealed a well-defined proliferation of dilated thin-walled vessels filled with blood and lined by flattened bland-looking endothelial cells, so the diagnosis of cavernous hemangioma was confirmed (Fig. 3).
