A female patient with acute left lower quadrant pain for two days. She was surgically confirmed to have haemorrhagic infarction of the left ovary without any space occupying lesion. a T2-weighted MRI depicts an enlarged left ovary with hypointensity of the peripheral stroma and peripherally deplased follicles (arrows). b ADC map shows diffusion restriction of the peripheral stroma (arrows) with a very low ADC value (0.78 × 10−3 mm2/s). c Gross pathological specimen shows enlarged and haemorrhagic left ovary compatible with haemorrhagic necrosis. d Microscopy reveals haemorrhagic necrosis
