Imaging findings of fibroid torsion in pregnancy: A case report

When our patient presented emergently to labor and delivery at 18 weeks pregnant with severe right abdominal pain, the common diagnoses (such as appendicitis, cholecystitis, etc.) were on the top of the differential. However, US and MRI revealed a rarer cause of her pain, a pedunculated fibroid. The most important question then became whether this fibroid had torsed, which would require surgical intervention to prevent life-threatening sequelae. Unfortunately, presurgical imaging diagnosis of fibroid torsion in pregnancy is difficult. We offer a description of our patient's imaging findings, which align with other radiologic descriptions of fibroid torsion in pregnancy in the literature, to contribute to the radiologist's diagnostic confidence in this patient population.
