“…MSCT angiography has an emerging clinical role in vascular imaging. It has potentially significant advantages over conventional angiography and CT scans in pelvic tumor diagnosis, especially with regard to differentiating between benign and malignant disease states and assisting in disease management (8)(9)(10)(11)(12).…”

“…Imaging is required to distinguish between gynecological, gastrointestinal, and neurogenic origin tumors as all can present similarly in the pelvic region (1). However, radiologists often have difficulties in diagnosis of exogenous and ectopic tumor origins using routine CT, as a wide spectrum of benign and malignant pathology present similarly in terms of shape, structure, enhancement, origin, and localization (10). Hence, diagnostic accuracy of pelvic tumors of unknown origin is traditionally low (1, 2).…”

“…A small number of these tumors form ectopic masses directly in the abdominopelvic cavity. In such cases, the source organ is often disfigured, and thus, it can be difficult to differentiate such tumors from tumors arising from abdominal organs (1,(8)(9)(10). Imaging can reveal characteristics that differentiate the origin of pelvic tumor, especially gynecological origin tumors from non-gynecological origin tumors (1).…”

ORIGINAL ARTICLE PURPOSE We aimed to compare multislice spiral computed tomography (MSCT) angiography diagnosis with both surgical findings and postoperative pathological results in patients with pelvic tumors of unknown origin. In addition, the diagnostic accuracy of MSCT angiography was compared with that of routine computed tomography for tumor feeding artery volume reconstruction to determine the origin and nature of pelvic tumors. MATERIALS AND METHODSThe records of 43 patients with pelvic tumors of unknown origin who underwent MSCT angiography were retrospectively reviewed. Volume reconstructions using add vessel and merge views methods were performed for abdominal and pelvic blood vessels. The tumor origin was identified based on observations of the origin, number, morphology, starting/ending locations, route, and distribution of the tumor feeding arteries. RESULTSOverall, the mean tumor diameter was 9.8±3.5 cm (range, 4.2-23.5 cm); 11 tumors (25.6%) were cystic in nature; and 32 tumors (74.4%) were either solid/cystic or solid in nature. When considering all MSCT angiography examinations used to predict the nature of the tumor (e.g., malignant or benign), the sensitivity and specificity were 77.3% and 95.2%, respectively. The positive and negative predictive values were 94.4% and 80%, respectively. The overall diagnostic accuracy was 86.05% with an area under the curve of 0.961 (95% confidence interval, 0.913-1.000). CONCLUSIONS MSCT angiography volume reconstruction for pelvic tumor feeding arteries of unknown origin is highly valuable for localization, qualitative diagnosis, and quantitative diagnosis of pelvic tumors.

“…Pelvic hematoma may be seen in various clinical scenarios, and is common after surgery or trauma (61). On MRI, acute components of hemorrhage typically have low signal intensity on T1-weighted and T2-weighted images, whereas subacute components of hemorrhage have high signal intensity onT1-weighted images and variable signal intensity on T2-weighted images.…”

“…Tumors occurring in this space are extremely rare (63). Congenital lesions account for about half of all tumors and epidermoid, dermoid, developmental cysts (Fig 16), and teratomas are the commonest (61). A dermoid cyst is more likely if MRI confirms the presence of fat content on fat-saturated images (Fig 17).…”
