Aggressive Resection for a Primary Leiomyosarcoma of the Vena Cava Masquerading as a Pancreatic Head Tumor.

Abstract

Smooth muscle is a normal component of the inferior vena cava (IVC) wall. Although uncommon, the smooth muscle component may undergo neoplastic change. Benign neoplasms are termed leiomyomas, and when there is a malignant change, the nomenclature is changed to an IVC leiomyosarcoma. Leiomyosarcomas of the IVC are rare, with less than 150 cases reported in medical literature. Unfortunately, the majority of IVC leiomyosarcomas are diagnosed at advanced disease stages. Surgical resection of locally advanced lesions is technically challenging, but complete resection is the mainstay of treatment as leiomyosarcomas respond poorly to chemo-radiotherapy. Due to the advanced disease stage at diagnosis and the technical complexity of IVC resection and reconstruction, most patients are transferred to high-volume centers in developed nations. We report a case of a patient with a locally advanced leiomyosarcoma masquerading as a pancreatic head tumor. This patient could not access care in a high-volume center and required aggressive maneuvers to resect the IVC leiomyosarcoma in a resource-poor, low-volume center. We present this case to highlight the steps in operative management and also to show that these procedures can be carried out in resource-poor environments once there is meticulous planning, appropriate equipment, and multidisciplinary care.
