This Review documents examination techniques, sonographic features and clinical considerations in ultrasound assessment of gynecological tumors. The methodology of gynecological cancer staging, including assessment of local tumor extent, lymph nodes and distant metastases, is described. With increased technical quality, sonography has become an accurate staging method for early and advanced gynecological tumors. Other complementary imaging techniques, such as computed tomography and magnetic resonance imaging, can be used as an adjunct to ultrasound in specific cases, but are not essential to tumor staging if sonography is performed by a specialist in gynecological oncology. Ultrasound is established as the method of choice for evaluating local extent of endometrial cancer and is the most important imaging method for the differential diagnosis of benign and malignant ovarian tumors. Ultrasound can be used to detect early as well as locally advanced cancers that extend from the vagina, cervix or other locations to the paracolpium, parametria, rectum and sigmoid colon, urinary bladder and other adjacent organs or structures. In cases of ureteric involvement, ultrasound is also helpful in locating the site of obstruction. Furthermore, it is specific for the detection of extrapelvic tumor spread to the abdominal cavity in the form of parietal or visceral carcinomatosis, omental and/or mesenteric infiltration. Ultrasound can be used to assess changes in infiltrated lymph nodes, including demonstration of characteristic sonomorphologic and vascular patterns. Vascular patterns are particularly well visualized in peripheral nodes using high resolution linear array probes or in the pelvis using high-frequency probes. The presence of peripheral or mixed vascularity or displacement of vessels seems to be the sole criterion in the diagnosis of metastatic or lymphomatous nodes. In the investigation of distant metastases, if a normal visceral organ or characteristic diffuse or focal lesions (such as a simple cyst, hepatic hemangioma, renal angiomyolipoma, fatty liver (steatosis)) are identified on ultrasound, additional examinations using complementary imaging methods are not required. If, however, less characteristic findings are encountered, especially when the examination result radically affects subsequent therapeutic management, an additional examination using a complementary imaging method (e.g. contrast-enhanced ultrasound, computed tomography, magnetic resonance imaging, positron emission tomography) is indicated.

PMID:Ultrasound scanning of the pelvis and abdomen for staging of gynecological tumors: a review. 2189 32

A 66-year-old female with history of endometrioid endometrial carcinoma was admitted to our institution with abdominal and pelvic pain. A CT scan revealed a mass within the right upper kidney with a tumour thrombus that extended through the right renal vein up to the point of confluence with the inferior vena cava (IVC). The imaging features of the mass strongly suggested a diagnosis of renal angiomyolipoma (AML) with renal vein thrombosis. The patient was proposed an open radical right nephrectomy with right renal thrombectomy for histopathological confirmation of the diagnosis of AML with extension to the right renal vein and preventing complications such as potentially fatal pulmonary thromboembolism. The implantation of a temporary IVC filter before surgery was recommended.
