Non-gynaecological masses arising in the pelvis may masquerade as gynaecological pathology with a potential delay in appropriate diagnosis and management. The purpose of this exhibit is to familiarise the viewer with the multimodality imaging appearances of these pelvic masses proven to be non-gynaecological by histology or follow-up.


Review of pelvic anatomy with particular attention to differentiating: Gynaecological from non-gynaecological masses Intraperitoneal from extraperitoneal masses. The imaging appearances of a variety of non-gynaecological pelvic masses are reviewed, with pathological correlation where available, including: Schwannoma & arachnoid cyst Lipoma & Spigelian hernia Lymphocele & haematoma Hydronephrosis Appendix mucocele Sigmoid mesenteric & peritoneal inclusion cysts amongst others.


Teaching points: Non-gynaecological pelvic masses may present to the gynaecologist and present a challenge to the unwary radiologist. Imaging plays an important role in determining the correct diagnosis of these lesions thus facilitating appropriate management.
