Fig. 1From: Torsion of a pedunculated subserous leiomyoma: a case report of a rare cause of acute abdominal pain in a pregnant womanMRI shows a well-defined and heterogeneous tumor, with predominantly high signal intensity on coronal (a) and axial T2-weighted images without (b) and with (c, d) fat saturation images; it contains hyperintense areas on axial T1-weighted images (e) consistent with the presence of blood content (yellow asterisk). It also demonstrated a hypointense vascular pedicle representing feeding vessels that arise from the uterine arteries, coursing from the uterus into an adjacent exophytic pelvic mass (yellow arrow) —“bridging vessel sign”; this sign reveals the uterine origin of the pelvic mass. A single fetus is also seen (orange asterisk)Back to article page
