Pseudoaneurysm formation is an uncommon complication of simultaneous aortic and renal artery revascularization procedures that has been noted to occur primarily at sites of anastomosis. We present the computed tomographic and angiographic findings of an unusual case of contained leak arising from the proximal renal artery stump with associated inferior vena caval compression and thrombosis in a patient who had had abdominal aortic aneurysmectomy and bilateral aortorenal bypass.

CT diagnosis of idiopathic aneurysms of the thoracic systemic veins.

Three patients with idiopathic aneurysms of the superior vena cava, left innominate vein, and inferior vena cava are presented. The advantages of CT over other diagnostic modalities are discussed.

Computed tomography of partial unilateral agenesis of the pectoralis muscles.

The most common congenitally absent muscles are the pectoralis major and minor. Absence is usually incomplete. This anomaly is often one component of a syndrome associated with other hand (Poland syndrome) and thoracic anomalies. Computed tomography can identify partial absence of the pectoralis muscle and exactly define the altered anatomy. A patient with myasthenia gravis and isolated partial agenesis of the pectoralis muscle is presented.

Hemorrhagic adrenal metastases: CT findings.

Adrenal hemorrhage secondary to metastases is uncommon. We have encountered four such cases that presented as large adrenal masses. In all cases the CT findings were of an inhomogeneous mixed-density adrenal mass with extensive perirenal changes suggestive of perirenal hemorrhage or mass. When such a lesion is seen, hemorrhagic adrenal metastases should be considered. Fluid may be of high density, suggestive of hemorrhage. However, as the adrenal is in the perinephric space, hemorrhage from any cause (trauma, metastases, or anticoagulant) in the adrenal gland will gravitate into the perinephric space.
