Infiltrating spinal angiolipoma

Spinal epidural angiolipoma: A rare cause of spinal cord compression

“…Spinal epidural angiolipomas are rare, benign tumors, with only 128 cases reported in the literature till now. [1,2,[6][7][8][9][10][11][12] The most common location of angiolipomas is in the soft tissues of the extremities, trunk, or neck. Berenbruch first described a case of spinal angiolipoma in 1890.…”

Spinal angiolipoma in a pregnant woman presenting with acute epidural hemorrhage

“…[1][2][3][4][5][6][7][8][9][10][11] Of these, SA were located epidurally in 127 patients (94.8%). In these 127 patients, SA were found in the cervical region in two patients (1.6%), in the thoracic region in 96 patients (75.6%), in the lumbar region in 15 patients (11.8%), in the cervico-thoracic region in five patients (3.9%), in the thoracolumbar region in four patients (3.1%), and in the lumbo-sacral region in five patients (3.9%), with a female predominance (male:female = 50:77).…”

“…1,2 Pregnancy was assumed to be an aggravating factor for epidural SA in 15.5% of the 77 female patients reported. 1,2,[4][5][6][7][8][9][10] In rare instances, SA manifested as acute epidural or subarachnoid hemorrhage in non-pregnant patients.…”

Hemorrhagic onset of spinal angiolipoma

“…Noninfiltrating angiolipomas are well defined and separate from the surrounding tissue and can usually be easily removed via laminectomy and dissecting techniques. Infiltrating spinal angiolipomas ideally require a wider resection; 4,5 however, even cases of subtotal resection of the infiltrating variant reportedly have good outcomes 17 in terms of spinal cord decompression. One case of preoperative embolization of an infiltrating angiolipoma has been previously described, and the authors reported that this maneuver allowed complete removal with minimal intraoperative blood loss.…”
