Extrahepatic biliary obstruction secondary to metastatic cancer.

Thirty patients with extrahepatic biliary obstruction secondary to metastatic cancer were reviewed to determine the sites of the primary tumor, diagnostic methods, therapy and success of palliation. Colon carcinoma was the most common primary tumor, and the common bile duct was most often obstructed. Both percutaneous transhepatic and surgical decompression of the biliary tract were employed.

The variable manifestations of extraarticular synovial chondromatosis.

Clinically, patients with extraarticular synovial chondromatosis are seen with a juxtaarticular mass due to metaplasia of synovial cells and subsequent formation of cartilaginous nodules. Three patients are described to illustrate the varied clinical and radiographic features of this disease. One patient had involvement of the knee and wrist while another had involvement of the knee along with presumed intraarticular synovial chondromatosis of the elbow.

Multiple paranasal sinus mucoceles.

The clinical and radiological findings in a 56-year-old woman with mucoceles involving the left frontal, both ethmoidal, sphenoidal, and right maxillary sinuses are presented. The predisposing cause was thought to be previous facial fractures. The rarity of this combination of lesions is discussed, including a brief review of the literature.

Radionuclide imaging in herpes simplex encephalitis.

Eight patients with herpes simplex encephalitis among the 10 cases diagnosed at the University of Kansas Medical Center from 1966 to 1976 were studied with 99mTc early in their diagnostic work-up. The images were unilaterally positive in the temporal lobe area in all 8 patients. Radionuclide studies can suggest herpes simplex as the specific etiology in cases of encephalitis and can also indicate the best site for brain biopsy to confirm the diagnosis by fluorescent antibody techniques.
