Leiomyosarcoma of the inferior vena cava. Ultrasonographic appearance.

Abstract

Ultrasonographic features of six leiomyosarcomas of the inferior vena cava are described. In most cases, the presentation is typical enough to strongly suggest the histologic diagnosis. The tumor is usually greater than 10 cm long, hypoechoic, heterogeneous. Cystic components can be found. It is sharply demarcated from neighboring organs which are displaced. The mass is located at the very place of the inferior vena cava, the lumen of which is no longer seen. It is fusiform shaped, surprisingly sparing the aorta. Differential diagnosis along with other radiologic examinations, pathologic findings, and prognosis are discussed.

Multimodal ultrasonographic assessment of leiomyosarcoma of the femoral vein in a patient misdiagnosed as having deep vein thrombosis

“…Thus, the above unusual finding led us to question our earlier diagnosis, and we took a multimodal ultrasonographic imaging approach to make a more precise diagnosis. According to Bousquet et al, [ 10 ] LMS of the inferior vena cava are usually >10 cm long, hypoechoic, and heterogeneous; a cystic component also can be found, which is estimated to be related to tumor necrosis. However, no cystic component was found in our patient.…”

Leiomyosarcoma of the Inferior Vena Cava

“…The tumor can arise from all the segments of the IVC, which can be divided into 3, as follows: (1) inferior segment-below the renal veins;…”

“…In 1986, Bousquet collected 94 cases from world literature. 1 Since then, 8 more cases have been published.…”

Inferior vena caval leiomyosarcoma: Diagnosis and biopsy with color Doppler sonography

“…An ultrasound-guided biopsy was performed thal, in part due to the late onset of symptoms. 2 The appearance of this neoplasm with multiple using an 18-gauge, spring-loaded trigger device. The procedure took approximately 20 minutes, imaging modalities has been described.…”

“…Frequent sites of metastases include liver an echogenic mass filling and distending the enand lung. 2 Moreover, extension into the right tire IVC with extension above the diaphragm atrium usually precludes surgical resection, as in ( Figure 1A). With color Doppler imaging, areas this case.…”
