Abstract

Spinal capillary hemangiomas in the epidural space are extremely rare; however, a preoperative radiological diagnosis is very important because of the risk of massive intraoperative hemorrhage. We report a case of a spinal capillary hemangioma involving the lumbar epidural and paraspinal spaces.

• 

  Fig. 1 Lumbar MRI of a 54-year-old man presenting lower extremity weakness. A Dumbbell-shaped mass involving both epidural and paraspinal space is noted. On T2-weighted axial image (A), hemorrhagic and cystic portion of the mass are shown as a low signal intensity area (arrowhead) and a high signal intensity area (arrow), respectively. On pre-contrast axial T1-weighted image (B), the mass is generally iso-intense to adjacent muscle with some heterogeneity. On post-contrast axial T1-weighted image (C), the mass enhances well with areas of non-enhancement suggesting hemorrhagic (arrowhead) and cystic portion (arrow). At anterior aspect of paraspinal mass, partially infiltrative portion is noted (double arrow).

• 

  Fig. 2 A photograph show numerous, tightly packed, capillary size vessels (arrows) that were lined by a single layer of cytologically benign endothelial cells (arrowheads) (H&E, × 400 section).
