UTERINE CIRSOID ANEURYSM - MRI AND MRA

Uterine cirsoid aneurysm is uncommon. It is important to make a diagno sis of this disease preoperatively, because repeated curettages may in duce life-threatening massive genital bleeding. We present a case of a 51-year-old woman with uterine cirsoid aneurysm in whom MRI and MRA w ere very useful for the preoperative diagnosis. The radiologic appeara nces on ultrasonography, CT, conventional SE MRI, MRA, dynamic MRI, an d pelvic angiography are presented. Conventional SE T1-weighted and T2 -weighted images demonstrated multiple flow voids in the uterus and bi lateral adnexal regions, MRA demonstrated a cluster of distinct, tortu ous, and coiled vascular channels in the pelvis. MRA could obtain imag es almost equal to angiography and was considered to be an excellent n oninvasive imaging technique for the diagnosis of uterine cirsoid aneu rysm.
