Spinal epidural angiolipoma complicated by an intratumoral abscess

Abstract

Spinal angiolipomas are rare, benign lesions representing 0.14 to 1.2% of all spinal axis tumors. They most commonly involve the midthoracic spine and are located in the posterior epidural space. Up to now, six pediatric cases have been reported in the literature; two of them involved an acute clinical onset that was related to a venous infarction of a tumor. The authors report the case of a 16-year-old boy with a midthoracic epidural angiolipoma who was admitted with a clinical history of an acute paraparesis. In contrast to previous descriptions, the acute onset in this case was related to a spontaneous intratumoral abscess within the tumor.

Spinal extradural angiolipoma: report of two cases and review of the literature

“…In two cases, the angiolipoma was associated with another tumor, osteochondroma [86], and glioblastoma [34]. Inmunoshistochemical assay was performed in a few cases [60,79] and a low proliferation rate was found on Ki-67 [22,68]. Samdami et al [80] observed a positive stain for CD31, Factor XIIIa, and Factor VIII, and negative for Glio Fibrilar Acid Protein.…”

Rectal angiolipoma: A case report and review of literature

“…They are generally subcutaneous and capsulated, about 50% patients feel painful on palpation, and seen in young adult males in their 2nd or 3rd decades of life [1,2,24] . They are also localized in neck [4,31] , maxillofacial region [32][33][34][35] and nonsubcutaneous tissues such as epidural [36] , spinal [37][38][39] , and suprasellar tissues [40] . Lipomas are seen more frequently, but angiolipomas are rare lesions [1,5] .…”

Sudden onset of paraplegia caused by hemorrhagic spinal epidural angiolipoma. A case report

“…They generally produce a slow progressive spinal cord or radicular compression [1]. Acute myelopathy is exceedingly rare [2,5]. To our knowledge, we present the first case of an intraspinal bleeding from an epidural angiolipoma producing hyperacute paraplegia and simulating an extradural hematoma.…”

“…Finally, indirect compression of the anterior radiculomedullary artery can be responsible for neurological symptoms. Recently, Petrella reported a case with acute spontaneous intratumoral abscess [5].…”

“…About a hundred cases were previously reported [1,5,7]. They generally produce a slow progressive spinal cord or radicular compression [1].…”
