30-year-old female with vaginal bleeding. Evaluate for AVM, which was suspected on recent pelvic ultrasound. PELVIS:UTERUS, ADNEXA: New 2.2 x 1.6 cm dark T2 signal lesion in the left uterine fundus with round and curvilinear morphology in a somewhat serpiginous appearance, suspicious for vascular flow voids. The lesion is centered within the myometrium with probable subendometrial extension. Lesion demonstrates avid arterial enhancement. Overall, findings are suspicious for arteriovenous malformation. Contrast opacification of the right gonadal vein on arterial phase images raises the question of venous shunting. There is a small amount of low T2, high T1 signal hemorrhage in the adjacent endometrial canal within the fundus. No suspicious adnexal masses.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Findings suspicious for arteriovenous malformation within the left uterine fundus, as detailed above. Additional considerations for enhancing uterine mass, such as retained products of conception, are considered less likely given the T2 appearance of the lesion. These findings should be correlated with recent pelvic ultrasound.
