The inferior vena cava (IVC) syndrome as the initial manifestation of newly diagnosed gastric adenocarcinoma: a case report

Abstract

There are very few reports of inferior vena cava (IVC) compression, in contrast to the SVC syndrome, as a manifestation of underlying malignancy. Some tumors have been reported to have compressive effects on the IVC. A recent case report showed that IVC compression was caused by a mesenteric desmoid tumor in a patient who presented with acute pulmonary embolism [6]. Neuroblastoma in a neonate who had lower extremity edema was shown to cause IVC compression [7]. Two cases of paragangliomas have been reported to cause IVC compression posteriorly [8].
