Polypoid endometriosis of post vaginal fornix: utility of MRI imaging of pelvis with diffusion weighted imaging for diagnosis

ABSTRACT

Polypoid endometriosis is an uncommon variant of endometriosis which can mimic malignancy due to its presentation as masses. We present a case of polypoid endometriosis which simulated cervical malignancy both on clinical examination and on computed tomography (CT) scanning and discuss how magnetic resonance (MR) imaging, in particular Diffusion Weighted Imaging (DWI), can help to distinguish this condition from true malignancy and avoid invasive surgery.
