a A 26-year-old pregnant woman at 27 weeks’ gestation presented with right-sided abdominal pain. Transversal transabdominal ultrasound of her right lumbar region showed a 9.16 × 9.73 cm, round, well-demarcated and partly hypoechoic/isoechoic structure, appearing to be in contact with her uterine wall. b Magnetic resonance imaging of her abdomen, coronal view: Type III rectus sheath hematoma (1) measuring 11 × 12 × 20 cm, mainly located at the right side and starting to displace her uterine wall. The placenta (2) is located at the rear aspect of her uterus and appears to be normal, without sign of acute abruptio placentae. c Magnetic resonance imaging of her abdomen, axial view: The fetus (3) is lying in cephalic presentation. Note the associated edema of the subcutaneous tissue
