Primary malignant fibrous histiocytoma (MFH) is an unusual tumor which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It rarely arises in the liver and, to our knowledge, the MRI appearance of primary MFH of the liver has never been reported. We present a patient with primary MFH of the liver and discuss the findings on MRI, CT, and angiography.
Safe angioplasty of a portacaval shunt requires particular knowledge of the tissue characteristics of an anastomosis and the behavior of a balloon during inflation. The nature and true diameter of a portacaval shunt anastomosis are more difficult to evaluate than those of a peripheral arterial lesion, and complications are potentially more hazardous than those related to peripheral arterial angioplasty. We suggest that in some instances low pressure and incomplete balloon inflation are all that is necessary to yield safe and satisfactory results.
In recent years interventional radiology has played an increasingly important role in the diagnosis and treatment of lung cancer. Useful interventional procedures include biopsy techniques, direct infusion of chemotherapeutic agents into neoplasms, and a number of palliative procedures. The article reviews the indications, contraindications, techniques, and complications of these procedures with emphasis on some of the newer procedures.

Seven cases of calcific tendinitis of the gluteus maximus tendon are presented. Awareness of the precise anatomic location of the calcific deposit is essential for the accurate diagnosis of this uncommon site of tendinitis. Clinically, the presenting complaint is that of pain. In some instances, however, the patients are asymptomatic and the calcification is an incidental finding.
