摘要
We described a case of a 71-year-old woman with an epithelioid hemangioendothelioma (EHE) in her left axilla,a rare location which hasn’t been reported yet.The patient suffered from numbness,pain and decreased muscle strength of her left upper extremity. Sonography revealed a hypoechoic mass surrounded the axillary artery and brachial artery. No obvious capsule was demonstrated.CT showed a soft-tissue mass with some calcifications and peripheral ring-like enhancement. The MRI indicated a mass with mainly intermediate signal intensity on T1-weighted imagine and intermediate signal intensity on T2-weighted imagine. The diagnosis was confirmed by histopathologic examination after surgery. There are some correlations of these imaging features with its histopathologic characters.
