Spinal extradural angiolipoma: a report of two cases and review of literature.

Spinal extradural angiolipomas (SEALs) are extremely extraordinary benign extradural lesions. They are infrequently encountered in normal clinical practice although several authors have report single cases or case series. We present two cases of SEAL which we successfully surgical resected with no further neurological deficits. Our cases comprise of a male and a female with ages ranging from 30 to 60 years. Their principal presenting complains were numbness and pain at the lower extremity with associated fecal and urinary incontinence. In all our cases, MRI revealed extradural spinal lesions that exerted compressive effect on the spinal cord. The male patient had an infiltrating type while the female had non-infiltrating type. We attained total resection in both cases without any further neurological complication. The diagnosis of SEALs initially can be challenging radiologically since they may mimic other spinal lesions. The gold standard treatment modality should always be surgery although total resection may not be achievable in some cases.
