A left-sided ovarian cyst is noted 5 cm in average diameter, with focal dependent eccentric dark T2 nodule. It shows T1 hyperintensity not suppressed on fat sat, with T2 shading. It shows a thin wall with mild enhancement and no mural soft tissue component. No diffusion restriction.
Case Discussion
MRI features are consistent with left-sided endometriotic (chocolate) cyst. T2 dark spot sign is demonstrated, which indicates chronic hemorrhage, differentiating endometriotic cyst from a functional hemorrhagic ovarian cyst, as both show high T1 signal with T2 shading.
