Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.

Cardiac myxomas are the most common type of benign cardiac tumors and most of them occur in the left atrium but the biatrial myxoma is uncommon. We present a rare case of giant biatrial myxoma nearly obstructing the orifice of the inferior vena cava. A 58-year old woman presented with exertional dyspnea and intermittent chest discomfort. The non-pedunculated tumor involved most of the interatri...

Congenital agenesis of the inferior vena cava is an uncommon congenital anomaly which can be misdiagnosed. Agenesis of the inferior vena cava has an incidence of 0.0005% to 1% in the general population [1]. The most common cause of agenesis of the inferior vena cava is the failure of embryological development between the sixth and the tenth weeks of gestation. Heterotaxy syndrome is associated ...

Ascending aortic aneurysm is a rare cause of superior vena cava syndrome. Herein, we describe a case of superior vena cava syndrome caused by a chronic dissecting aortic aneurysm after aortic valve replacement. A successful replacement of the aortic root and ascending aorta led to an improvement of edema of the face and bilateral upper limbs caused by superior vena cava syndrome.

conclusions our case showed that if the respiratory failure occurred due to substernal goiter and svcs, we would need to investigate the coexistence of osas and svcs. case presentation we presented the clinical course and treatment of acute respiratory failure (arf) developed in a patient with svcs and osas due to substernal goiter. after treatment of arf with invasive mechanical ventilation, w...
