Pain in the TMJ was not related to MR findings of effusion in internal derangement and synovial fluid aspirate findings of total protein concentration. However, total protein concentration was related to the amount of JE in DDwoR joints and painful joints were more likely to demonstrate the JE.

We report two cases of primary cardiac hydatid cyst in which hydatid materials caused recurrent embolizations in pulmonary arteries and pulmonary parenchyma. Cardiac hydatid cysts may stay asymptomatic for a long time, until they reveal themselves being perforated into cardiac chambers and/or pulmonary artery or systemic circulation. The role of imaging techniques in diagnosis is discussed and the importance of dynamic enhanced CT, MR imaging, and enhanced MR angiography (MRA) is reported. Imaging findings were confirmed by surgery and pathology. Early diagnosis is essential because delayed treatment increases the morbidity and mortality rates.

The US, CT, and X-ray findings in a patient with omental fibroma of the lesser omentum are described. Ultrasound showed a solid mass with cystic areas in the central region. At CT the lesion showed peripheral enhancement and central hypodensity. On X-ray studies with barium, there was border distortion in the lesser curvature of the stomach. The mass was resected surgically. A pathologic diagnosis of fibroma was confirmed.

Meniscal extrusion is a common finding particularly in osteoarthritis. It is mostly seen in the medial meniscus and accompanied by radial tears. Therefore, its presence should alert to the possibility of a radial tear extending to the meniscal root.
