The obstruction of inferior vena cava(IVC) is uncommon condition. The classification is based on the obstructive sites of major anatomic segments of IVC. The main collateral pathways of interruption of IVC were central channels through ascending lumbar veins, intervertebral veins and azygos-hemiazygos complex. However, the complete obstruction of mid-portion of IVC, accompanying collateral cirulation with pericardiacophrenic vein was rarely reported. We had experienced a case of complete obstruction of mid-portion of IVC with lobulated left cardiac border, which was unforgettable characteristic finding on chest radiograph. It was confirmed by venographic examination that the lobulated left cardiac shadow was a collateral circulation of pericardiacophrenic vein.

We recently encountered a patient with membranous obstruction of the inferior vena cava in whom the left superior intercostal and hemiazygos veins were dilated. At chest radiography, the dilation simulated the presence of a second aortic knob and descending thoracic aorta lateral to the originals, and an "aorta-in-aorta" appearance was thus created.

We experienced a case of transient right-sided heart failure after angioplasty of membranous obstruction of the inferior vena cava confirmed by sonography and an inferior vena cavogram. Angioplasty involved the use of a self-expandable metallic stent, but after successful recanalization of the obstruction , the patient became dyspneic. Chest radiography revealed mild cardiomegaly with pulmonary congestion, but this was resolved spontaneously. For the prevention of serious heart failure, we recommend preprocedural evaluation of cardiac function.

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cyst. Recently, we observed a Eustachian valve cyst diagnosed on MDCT showing a hypodense cyst at the characteristic location of the Eustachian valve (the junction of the right atrium and inferior vena cava). MDCT also demonstrated additional cardiovascular anomalies including atresia of the coronary sinus ostium and a persistent LSVC and bicuspid aortic valve.

Stromal tumors of the gastrointestinal tract, especially of the esophagus, are rare. We had a case of malignant gastrointestinal stromal tumor(GIST) of the esophagus. A 46 years old woman was admitted for abnormal mass shadow in the chest radiograph. The mass was originated from the lower thoracic esophagus, and compressed the right lower pulmonary vein and the inferior vena cava. We removed the tumor externally without injuring of the esophageal mucosa via right posterolateral thoracotomy. The tumor was positive for CD 34 and CD 117, and diagnosed malignant GIST of the esophagus.

Anomalies of renal vasculature combined with ectopic kidneys were found on a multi-detector CT scan. Knowledge of renal vascular variation is very important for surgical exploration, radiologic intervention and staging for urologic cancer. We present an extremely rare case of a right circumaortic renal vein combined with a right ectopic kidney. The right kidney was located at the level between the third and fifth lumbar vertebra. The right circumaortic renal vein crossed the aorta and returned to the inferior vena cava behind the aorta.

Yolk sac tumor (YST) is a rare germ cell neoplasm of childhood that usually arises from the testis or ovary. The rare cases of YST in various extragonadal locations have been reported, but the primary intrarenal YST is even more uncommon. Here, we report a case of a primary intrarenal YST with tumor thrombus of the inferior vena cava and left renal vein in a 2-year-old boy, with an emphasis on the CT features. To our knowledge, this is the first reported case of an intrarenal YST with intravascular involvement.

Behcet's disease is a chronic multisystemic disorder involving many organs and characterized by recurrent oral and genital ulcers and relapsing iritis. A case of BD with large vein thrombosis involving superior and inferior vena cava is presented. Large vein thrombosis in BD is not commonly developed and most commonly observed in the inferior or superior vena cava. A review of the literature emphasizes the rarity of the combined superior and inferior vena caval occlusion. Existence of extensive large vein occlusion in BD is associated with limited therapy and poor prognosis.

A 60-year-old female presented with abdominal pain and tenderness of five-day duration. Contrast enhanced CT showed a mass of 9 x 6 x 5.5 cm in size with almost complete obliteration of the inferior vena cava and massive extension to the extravascular space. CT-guided biopsy demonstrated a low-grade leiomyosarcoma. The patient underwent 125Iodine seeds implantation in two sessions, and another balloon cavoplasty. Abdominal pain and tenderness gradually improved and the patient continues to remain as disease free state for three years after the procedures.
