Haemorrhagic fibroid degeneration. This patient, known to have uterine fibroids, presented to the accident and emergency department with low-grade pyrexia, tachycardia and acute lower abdominal pain. a Sagittal T2 image demonstrates a large uterine fibroid with high signal intensity centrally with a very low signal intensity rim suggestive of peripheral haemosiderin. b Axial T1 with fat-saturated image shows high signal intensity within the fibroid consistent with haemorrhage (black arrow). c Axial T1 with fat saturation following gadolinium administration demonstrates lack of enhancement within the fibroid (black arrow), consistent with infarction. The surrounding myometrium enhances normally (white arrow)
