Background: The clinical presentation of non-Hodgkin lymphoma (NHL) varies tremendously depending upon the type of lymphoma and the areas of involvement. NHL can rarely present as an abdominal mass compressing the inferior vena cava. The clinical presentation due to obstruction of inferior vena cava has often been called the inferior vena cava syndrome (IVCS). It can present acutely or chronica...

superior vena cava syndrome is a common presentation of bronchogenic carcinoma. the mechanism of obstruction is by compression of superior vena cava by the bronchogenic tumor itself or enlarged mediastinal lymph nodes. however obstruction due to intravascular thrombosis is extremely uncommon. here, we report a rare case of a 65-year-old male smoker who presented with superior vena cava syndrome...

leiomyomas are benign tumors of the soft tissue and may develop in any location where smooth muscle is present. leiomyoma in the inferior vena cava is a rarely seen pathology, and symplastic leiomyoma is also a rare histological variant of leiomyoma. in this case, we present a rare histological variant of symplastic leiomyoma in the inferior vena cava (ivc). this is the first radiologically rep...

The inferior vena cava, due to its complex embryogenesis and relationship with other abdominal and thoracic structures, may develop abnormally. The anomalies and variations of inferior vena cava anatomy are very rare occurring in approximately 0.3% of the population. Among these latter, duplication of the inferior vena cava has an incidence of 2–3%. Usually, right inferior vena cava dominates a...

essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the digital ...

Venocaval anomalies are uncommon in the general population and often go unrecognized, but physicians should be aware of their significance. Duplicate superior vena cava should be identified during cardiac imaging, surgery, and catheter insertions. While interrupted inferior vena cava can predispose to thrombus formation, they protect against pulmonary embolism from lower extremity deep vein thr...
