RESUMEN
Malignant mesothelioma of the tunica vaginalis is rare, but sometimes curable. It is similar to malignant mesothelioma of the peritoneum and of the pleura, and is likewise associated with asbestos exposure. We report a case, with correlative computed tomography, ultrasound, and gross pathology images that demonstrate tiny tumor implants studding the vaginalis testis. The literature is reviewed.

Until recently, a definitive diagnosis of lipoma in the thorax could only be established by thoracotomy. We undertook this study to determine if chest CT could provide such an answer. Among 4,000 chest CT scans, six patients were found to have lipoma according to the following selected criteria: CT features of a pleural mass; a lesion showing completely homogeneous density with CT numbers indicating fat, and exclusion of other fatty lesions. In these six patients, the lipoma was an incidental finding, four were men, the mean age was 64.3 years, one-half were obese, and none had chest pains or dyspnea. Lesions varied in size from 2 to 4 cm and occurred along the chest wall. The CT numbers of the masses ranged from -54 to -129. None developed malignancy. In conclusion, we recommend clinical and chest CT follow-up for the asymptomatic patient who fulfills our CT criteria for lipoma. Biopsy or resection is recommended for lesions that are inhomogeneous.

Normal adult ovary volume determined by ultrasonography (US) is often stated to be less than 6 cm3. This is based on data from teenagers and young adults aged 12-20 years. Recently, the mean normal volume determined by US was reported to be considerably higher. We measured the volumes of 28 ovaries from 15 healthy young adults and found them to range as high as 13.84 cm3, with an average of 6.48 cm3.

Arthrography is considered extremely safe since reactions to intraarticular contrast media are rare. We have only seen one severe complication in the performance of more than 2,000 arthrographic procedures. To determine the incidence of complications, a questionnaire was sent to 84 radiologists experienced in arthrography. The 57 respondents had performed more than 126,000 arthrographic procedures, and findings of the survey indicate no deaths, three cases of infection, and 61 cases of hives. Other acute reactions included hypotension, seizures, air embolism, and laryngeal edema. Related complications included sterile chemical synovitis, severe pain after the procedure, and vasovagal reactions.

Because of rapid technologic advances, clearly defined clinical indications, and widespread availability, computed tomography of the lungs, pleura, and chest wall has become increasingly important in the imaging and subsequent management of numerous thoracic disorders. This article describes the current indications, common findings, and potential controversies in CT of the lung, pleura, and chest wall.
