We present the computed tomography (CT) findings of pseudothrombosis of the right ovarian vein. In two young multiparous women, pseudothrombosis was detected on early-phase spiral CT scans by the presence of retrograde flow of contrast medium down the left ovarian veins. Asymmetry of density seen in the ovarian veins in the early phase of spiral CT scanning related to reflux in the left ovarian vein should not be mistaken for right ovarian vein thrombosis.

Prostatitis is a common clinical syndrome that on rare occasions may result from mass lesions in the pelvis. This report concerns a man with debilitating prostatitis that was caused by a müllerian duct cyst. The diagnosis was facilitated by examination with magnetic resonance imaging using a pelvic phased array surface coil and a small field of view.

We present a case of diffuse lung calcifications that developed following fat emboli and adult respiratory distress syndrome. Computed tomography (CT) showed the majority of the calcifications to be within branches of the pulmonary arteries. High-resolution CT findings helped to characterize associated lung parenchymal changes.

We report a case of pseudoretroconversion in which, clinically and pathologically, it appeared that an endodermal sinus tumor retroconverted to mature teratoma. An 8-month-old white female infant with a sacrococcygeal tumor, diagnosed by biopsy as endodermal sinus tumor (yolk sac tumor), was treated with chemotherapy. The residual tumor after treatment was mature teratoma confirmed by imaging and by pathological examination. We present the computerized tomography (CT) and magnetic resonance imaging (MRI) findings with pathological correlation.

Organo-axial volvulus of the stomach, a potentially catastrophic situation, may be recognized as an incidental finding on computed tomography (CT). We present the CT features of organo-axial volvulus of the stomach in two cases. In one case, a correlative magnetic resonance (MR) image is presented.
