Spinal Angiolipoma-Case Report-

Abstract

A 69-year-old male presented with a rare spinal angiolipoma manifesting as history of back pain, and numbness in both lower limbs, which progressed over a period of 5 years. Total T10-T12 laminectomy was performed and the tumor was removed en bloc. The symptoms gradually improved postoperatively. Spinal angiolipoma is an uncommon benign extradural tumor of spine, which accounts for 0.14-1.2% of all spinal tumors and is a rare cause of spinal cord compression. Recognition of this entity is crucial as a benign and curable cause of paraplegia and back pain.

“…In adults, symptoms have also been described to progress during pregnancy, probably due to increased blood and extracellular fluid volumes as well as due to the increased epidural venous pressure. Some hormonal influence has also been suggested [13]. Tumor thrombosis and subsequent hemorrhage, vascular steal, and abscess formation have been described as causes of neurological deterioration [2,13].…”

“…Most angiolipomas are located posteriorly or posterolaterally, although anterior and anterolateral location has been described in tumors infiltrating the vertebrae [1]. MRI has been described to be the gold standard imaging modality with the tumor appearing to be hyperintensive and inhomogenous on T1-weighted images [13].…”

“…The non-infiltrating type has been described to be more common and often well encapsulated. The infiltrating type can potentially invade the bony structures of the spine and consists of mature lipocytes surrounded by proliferating blood vessels [13,17]. The ratio of fat to vessels has been reported to range from 1:3 to 2:3.…”

“…The ratio of fat to vessels has been reported to range from 1:3 to 2:3. Atypia, pleomorphism, mitosis or karyotypic abnormalities have not been reported [13].…”
