Infiltrating extradural spinal angiolipoma
1Department of Histology-Embryology-Cytogenetics, Hôpital Pitié-Salpêtrière, Paris, France.
Background:
Angiolipomas are considered to be rare. They are benign mesenchymal tumors generally located in the subcutaneous tissue of trunk and limbs.
Methods:
The authors report a thoracic epidural angiolipoma mimicking a vertebro-epidural metastasis. The patient suffered from medullary compression related to an extradural mass in T6.
Results:
Pathological ex-, amination was obtained from tumoral samples. They consisted of mature adipose tissue with numerous sections of abnormal vascular channels.
Conclusions:
Reviewing literature particular attention is paid to some questions raised in connection with different kinds of vertebro-epidural tumors. The authors give importance to relationships between angiolipomas and angiomyolipomas using MRI as a tool in differential diagnosis. Pathogenesis is evokated especially regarding the role of corticotherapy, the case herein reported lying within this therapeutical context.
