Endometriosis revisited: an imaging review of the usual and unusual manifestations with pathological correlation.

The manifestations of endometriosis commonly present a diagnostic challenge to the gynecologist and radiologist. Familiarity with its varied presentations may allow for a more accurate diagnosis. The goal of this review is to the present the imaging spectrum of endometriosis, less common sites of involvement as well as the potential rare complications. Relevant surgical and histopathological correlation is also provided. In addition to clinical evaluation and sonography, MRI is a highly accurate imaging modality in the diagnosis of endometriosis. It possesses a distinctive advantage over other modalities in that it allows a complete survey of the pelvic compartments. The potentially devastating effects of endometriosis include pelvic pain and even infertility. Since standard treatment is surgical, the radiologist needs to be familiar with the various manifestations in order to aid diagnosis for appropriate management.
