title: [Lymphangiosarcoma on a chronic edema of the lower limb. Radiologic study apropos of a case].
abstract: Lymphangiosarcoma is a rare tumor of the soft tissues, in particular outside of cases where the etiology is represented by chronic edema following mastectomy for breast cancer (Stewart-Treves syndrome). In the case reported, the patient experienced chronic edema of the lower limbs, with diffuse involvement of the right leg. The sonographic appearance revealing thickening of the dermis, with localized infiltration of the aponeurosis, and especially the angiographic findings showing hypervascularization with early venous return are discussed.
