title: Epithelioid sarcoma mimicking abscess: review of the MRI appearances.
abstract: A case of epithelioid sarcoma involving the soft tissues of the ankle is presented. The tumor was a hemorrhagic, fluid-filled, multiloculated lesion with inflammatory changes in the surrounding planes. Tuberculous abscess was diagnosed on the basis of the clinical picture, ultrasound and MRI findings. Surgical exploration of the ankle mass was carried out because of lack of local healing while the patient's general and pulmonary status improved on antituberculosis treatment. This was an unusual case of epithelioid sarcoma mimicking a multilocular abscess.
