“…As the leiomyosarcomas of the inferior vena cava grow, they eventually invade adjacent tissues and metastasize distantly; however, they tend to expand along the tissue plans of least resistance. There are no reported cases of tissue invasion of the adrenals, kidneys or bowels for leiomyosarcomas of the inferior vena cava (7). Like other retroperitoneal tumors, these tumors seldom present with symptoms until they progress into a huge mass.…”

“…The use of CT is superior to the use of sonography to reveal the highly enhancing and necrotic characteristics of the tumor, which is specific for the diagnosis of leiomyosarcoma (7). When CT shows a solid or necrotic extraluminal retroperitoneal mass not originating from a retroperitoneal organ, and possessing a contiguous intravascular enhancing appearance, it is accepted as a pathognomonic finding of vascular leiomyosarcoma (6).…”

Leiomyosarcoma of the Ovarian Vein: a Case Report with Radiological Findings

Leiomyosarcomas of the ovarian vein are very rare. Four cases have been reported in the English language clinical literature. We present a case of leiomyosarcomas where the use of multi-detector CT had a substantial role in the establishment of the preoperative diagnosis. The radiological images as well as intraoperative features are illustrated. We also discuss the radiological findings of the ovarian vein leiomyosarcoma in comparison with those of other venous or retroperitoneal leiomyosarcomas. We expect that the use of multi-detector CT will be the choice for the diagnostic work-up of vascular leiomyosarcomas.

“…Typically, these tumors are large solid masses with extensive areas of necrosis. Their relationship to vessel may be primarily exophytic, primarily intraluminal, or a combination of both [2][3][4]. This last pattern of growth, exophytic and intraluminal, is uncharacteristic of the other retroperitoneal tumors; therefore, demonstration of this pattern is highly suggestive of leiomyosarcoma [2].…”

“…Although CT and ultrasound aid in earlier recognition of retroperitoneal tumors [3][4][5][6][7][8][9] (which traditionally were discovered very late in their course or at autopsy), there remain limitations in diagnosis and pre-operative evaluation with these modalities. The distinct advantages of MRI have been described [2,3,10,11], including the capability of multiplanar imaging and assessment of vessel patency using flow-void and/or flow enhancement properties.…”

Primary leiomyosarcomas of the retroperitoneum are rare tumors, the vast majority of which are malignant. Prognosis is largely dependent upon adequacy of surgical resection. Magnetic resonance imaging (MRI) is ideally suited to the evaluation of these neoplasms because of multiplanar imaging capability, inherent signal intensity differences of tissues, and flow-void, flow enhancement techniques to assess vessel patency. Recent advances which include fat suppression, suspended respiration sequences, and Gadolinium enhancement, have further improved image quality. Accurate pre-operative assessment of tumors is possible with MRI.

“…However, in cases with a hypovascular tumor in the upper part of the abdomen, leiomyosarcoma of the inferior vena cava should be considered, especially if the tumor proves to be solid at ultrasonography (10). Computed tomography offers good delineation of tumors in the region of the inferior vena cava, but even with CT it may be difficult to decide the true origin of the tumor (5, 8,15,20). At ultrasonography the upper V3 of the inferior vena cava are almost always well demonstrated, while the lower V3 is often obscured by bowel gas.…”
