Epidural thoracic spinal angiolipoma: Removed with favorable outcome

Iván Andrés Freire-Figueroa · Pablo Alfredo Vargas-Ardila · María Camila Bonilla-Lersundy · Leonardo Andrés Chacón-Zambrano

Background: Spinal angiolipomas are rare benign epidural tumors accounting for 0.14–1.2% of all spinal neoplasms. Pathologically, these lesions are composed of mature adipose tissue and contain proliferative vascular elements. Here, a 44-year-old female presented with a thoracic epidural angiolipoma causing progressive...
