Lipoma arborescens of the knee: A case report.

Lipoma arborescens is a rare and benign intra-articular lesion characterized by a lipomatous proliferation of the synovial membrane, usually affects the knee joint. It presents as an unusual cause of intermittent knee pain and joint effusion. We report a case of lipoma arborescens of the knee in a 23-year-old man that initially resembled inflammatory arthropathy. The diagnosis of Lipoma arborescens was made by magnetic resonance imaging of the knee and confirmed histologically by synovectomy. The purpose of our case is to show the imaging features enabling early diagnosis and appropriate treatment.

Primary hydatid cyst of adrenal gland: Case report.

The hydatid disease is an anthropozoonose caused in humans by a larval form of Echinococcus granulosus. Adrenal gland is a rare and unsymptomatic site. We illustrate the case of a 46-year-old patient, admitted for left hypochondrial pain with back radiation. The CT reveals a multiloculated, cystic mass on the left adrenal gland, which contains septae and a calcified wall.
