PET/CT and MR Features of Infiltrating Spinal Angiolipoma

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

Spinal angiolipomas (SALs) are extremely rare benign tumors composed of both mature fatty tissue and anomalous vascular channels. We present two cases of SALs and review the clinical presentation, radiological appearance, pathological aspects, and treatment of this distinct clinicopathological mass. The patients’ neurologic symptoms improved postoperatively and follow-up revealed no signs of tumor recurrence or neurological deficit. SAL should be considered as a differential diagnosis in patients with spinal cord compression. Magnetic resonance imaging is important for detecting and characterizing SALs. The gold standard treatment modality should be total resection.

Epidural angiolipoma with concomitant intradural extramedullary capillary hemangioma at the same spinal level: A case report

Spinal epidural angiolipomas (SALs) and spinal intradural extramedullary capillary hemangiomas (SIECHs) are both types of rare benign tumor, and their pathogeneses appear to be associated. The present report is, to the best of our knowledge, the first case of spinal angiolipoma and intradural extramedullary capillary hemangioma occurring at the same spinal level. A 54 year-old male patient experienced two operations within four months due to the occurrence of SAL and one SIECH at the T3 level presenting with sudden paraplegia. Although the co-occurrence of SAL and SIECH at the same spinal level is an extremely rare condition, omitting the intradural tumor may be averted via scrutiny of preoperative images.
