Cross-sectional imaging of the pelvic tumors and tumor-like lesions in gynecologic patients—misinterpretation points and differential diagnosis

Abstract

Computed tomography and/or magnetic resonance imaging were performed in 42 female patients with suspected pelvic mass. Surgical and histopathological reports were compared to the imaging findings, yielding mismatch in five (17.8%) patients. One benign cyst and one case of postirradiation fibrosis were characterized as recurrent tumors, one surgically transposed ovary as metastasis, and an ovarian torsion as ovarian tumor, and a pelvic hematoma was mistaken for abscess. The most common false-positive finding on a per-lesion basis was that of enlarged lymph nodes.
