Incidental pulmonary embolism identified on chest CT during initial trauma evaluation.

Deep venous thrombosis and pulmonary embolism frequently occur after trauma and continue to account for significant morbidity and mortality in this population. Asymptomatic pulmonary emboli are also believed to be quite common, but the incidence as well as the implications of these events is unknown. This case report describes two patients whose pulmonary emboli were found incidentally on the initial trauma workup. Very little has been written concerning this issue and in this case report we review the risk factors and clinical significance of these "incidentally discovered" pulmonary emboli.

Isolated late recurrence of renal cell carcinoma in the inferior vena cava.

The occurrence of an isolated late recurrence of renal cell carcinoma within the inferior vena cava (IVC) is a rare event. We present a case of a 55-year-old patient with recurrence in the IVC more than 3 years following her initial nephrectomy. The asymptomatic presentation of this patient with recurrent disease emphasizes the importance of close, long-term surveillance.

ACR appropriateness criteria on obstructive voiding symptoms secondary to prostate disease.

Obstructive voiding symptoms are most commonly due to prostatic hyperplasia, but other causes include bladder neck contractures, prostatic carcinomas, neurogenic bladder, and urethral stricture. Symptoms include hesitancy, dribbling, decreased force of stream, and postvoid fullness. Imaging is useful in evaluating the presence and degree of hydronephrosis, estimation of renal function, evaluation of the bladder and prostate, and detection of incidental upper tract malignancies or stones. Various modalities have been used for evaluation of the cause of obstruction. Literature on the indications and usefulness of these radiologic studies for obstructive voiding symptoms in different clinical settings is reviewed.
