A 38-year-old man underwent surgical excision of a 1.5-cm subcutaneous nodule of the left leg. Histologic evaluation demonstrated the presence of an epithelioid hemangioendothelioma (EHE). The patient underwent 18F-FDG PET/MRI for staging. This examination demonstrated the presence of several soft tissue and bone lesions in the left lower limb without evidence of distant metastatic disease. The final diagnosis was multifocal EHE of the left lower limb. In this case, 18F-FDG PET/MRI has been very useful in the correct staging of this rare presentation of EHE of the lower limbs.
一位 38 岁男性接受了左腿 1.5 厘米皮下结节的手术切除。组织学评估显示存在上皮样血管内皮细胞瘤（EHE）。患者进行了 18F-FDG PET/MRI 分期检查。该检查显示左下肢存在多个软组织和骨病变，但无远处转移疾病的证据。最终诊断为左下肢多灶性 EHE。在这种情况下，18F-FDG PET/MRI 在正确分期这种罕见的下肢 EHE 表现方面非常有用。
