title: Infiltrating spinal angiolipoma.
abstract: Infiltrating angiolipomas are rarely encountered in the spine. We present a case involving a 71-year-old man with a dorsal epidural angiolipoma at the T5-T7 level. The tumor involved the T5-T6 vertebral bodies and left pedicle. The patient presented with acute paraparesis and MRI showed a homogeneously hyphointense lesion on T1-weighted images. The epidural component of the tumor was removed via laminectomy to achieve adequate cord decompression. The patient was symptom-free at a 2-year follow-up. This report emphasizes the unusual clinical presentation and MRI features of an infiltrating spinal angiolipoma and discusses therapeutic management options.
