Abdominal ultrasound
Computed tomography (CT) is very useful for evaluating the primary characteristics and secondary patterns of spread of such a neoplasm. It can show the extent of the primary tumour, identify metastases, and localise lesions for biopsy. The CT appearance of LMS is not specific.
The differential diagnosis of LMS includes other neoplasms such as leiomyoma, lymphoma, or other types of sarcoma and mucinous cystic neoplasm. Nevertheless a group of findings that occur rather frequently among patients may suggest consideration of this diagnosis. These include large masses with central necrosis or liquefaction and frequent liver metastases that also are often necrotic or cystic in appearance. The associated presence of pulmonary, mesenteric, omental, nodal, or soft tissue metastases, especially if necrotic, should suggest the diagnosis of LMS. Calcification is not usually observed in any of the tumour masses or metastases. Intravenous pyelogram, abdominal ultrasound, colonoscopy, double contrast barium enema and cysteoscopy, lemphangiography and MRI may also contribute to the diagnosis.
