RESUMO
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.

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.

A recently developed duplex ultrasonic imaging system that combines high-resolution real-time imaging with simultaneous Doppler analysis provides accurate evaluation of hemodynamically significant occlusive vascular lesions. This system was used in the evaluation of the extracranial carotid arteries, iliofemoral arteries, and hemodialysis shunts. The system obtains information regarding blood velocity, lumen area, plaque composition and ulceration, and hemodynamic turbulence. A total of 140 patients with hemodynamically significant lesions diagnosed by this method was evaluated angiographically. Correlation between the two modalities yielded a sensitivity of 0.94, a specificity of 0.88, and an overall accuracy of 0.92. The diagnostic information obtained can be used to differentiate potential surgically correctable lesions from those that require medical therapy or follow-up.

Obstruction of the afferent loop may develop in patients who have had a Billroth type II gastrojejunostomy. This obstructed loop has a characteristic but initially confusing computed tomographic appearance that might be mistaken for multiple peripancreatic cystic masses. Three cases of afferent loop obstruction due to gastric carcinoma are reported. In each case, the length of the jejunal segment incorporated into the afferent loop determined the number of cystic masses evident at each scan level. Recognition of the typical anatomic configuration and uniform size of these cystic masses is key to the correct diagnosis.
