Lumbar spinal epidural angiolipoma

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).…”

Hemorrhagic onset of spinal angiolipoma

“…These tumors might result from the abnormal development of primitive pluripotent mesenchymal cells, as postulated by Ehni and Love. 10,12 Recently, an electron microscopy study suggested that angiolipomas originate from active secretory adipocytes that contain lipid-like materials in perivascular granules. 2,10 The appearance of spinal angiolipoma can vary in imaging studies.…”

“…10,12 Recently, an electron microscopy study suggested that angiolipomas originate from active secretory adipocytes that contain lipid-like materials in perivascular granules. 2,10 The appearance of spinal angiolipoma can vary in imaging studies. On plain radiography, the lesions often yield negative results; however, in certain cases, they might show erosions of the pedicle and widening of the spinal canal.…”

“…On plain radiography, the lesions often yield negative results; however, in certain cases, they might show erosions of the pedicle and widening of the spinal canal. 4,6,10,12 The lesions are hypo-to hyperdense on CT scans, depending on the extent of the vascular component or the presence of calcification. Magnetic resonance imaging is the modality of choice when diagnosing spinal angiolipoma.…”

The subdural extramedullary angiolipoma: A rare case report and review of literature

“…They account for only 0.04% to 1.2% of all spinal cord tumors and have the predilection for the epidural midthoracic area. [1][2][3][4][5] Onset of symptoms is present in the fifth decade with a slight female predominance. [6] The epidural angiolipoma accounts for more than 90% of all reported cases.…”
