Spinal angiolipoma: Experience of twelve patients and literature

Abstract

In patients with spinal angiolipoma, total excision should be achieved and is associated with good outcomes.

Lumbar Spinal Angiolipoma with Expanding Left Neural Foramen Mimicking Lumbar Schwannoma; Case Report and Review of The Literature

“…Lin et al divided spinal angiolipoma into two groups: noninfiltrative and infiltrative [ 4 , 7 ]. The noninfiltrating spinal angiolipomas are frequently encapsulated and occur mostly in the posterior extradural space of the spinal cord.…”

“…The infiltrating types are rarely seen and partly or completely unencapsulated. They are located in the anterior and anterolateral extradural space of the spinal cord [ 7 ]. The prognosis of the noninfiltrating spinal angiolipomas is better than infiltrating types and they have an unfavorable prognosis [ 2 , 4 ].…”

“…In tumor, the rate of fat tissue to the vascular compartment ranges between 1/3 and 2/3 [ 7 , 8 , 21 ]. Vascular structures in some angiolipomas comprise almost the whole of the tumor.…”

“…Immunohistochemical examination from the literature was performed in some cases and Ki-67 index is also lower in angiolipoma [ 6 , 20 , 22 ]. Spinal angiolipomas are generally seen between the ages of 40 and 60 and especially in women [ 6 , 7 ]. There are few cases seen in children [ 2 ].…”

“…Spinal angiolipoma is a rare specific clinicopathologic entity, which is to be distinguished from skin angiolipoma [ 3 ]. Spinal angiolipomas comprises 0.04%-1.2% of all spinal cord tumors and spinal 2-3% of extradural tumors [ 2 , 4 - 7 ]. Most of spinal angiolipomas are seen in thoracic region of posterior extradural areas [ 5 , 8 ].…”
