The paper describes a 33-year-old woman with cyclic sciatica caused by histologically documented infiltrative endometriosis involving the left sciatic notch. It discusses how endometriosis typically shows on MRI as a mass with a large cystic component and variable T1/T2 signal from hemorrhagic degradation, but emphasizes that this case had an atypical infiltrative appearance without cystic-hemorrhagic components. The main contribution is the reported MRI findings corresponding to infiltrative sciatic endometriosis, with the key limitation being that this is a single case report, so findings are not generalizable. This paper is centrally about endometriosis — specifically infiltrative sciatic (sciatic notch) endometriosis presenting as cyclic sciatica with atypical MRI features.

Abstract

Endometriosis, an important gynecological disorder of reproductive women, affects most commonly the ovaries and less frequently the gastrointestinal tract, chest, urinary tract, and soft tissues. Endometriosis classically appears on MRI as a mass with a large cystic component and variable signal intensities on T1- and T2-weighted images due to the presence of variable degradation of hemorrhagic products. Endometriosis in an atypical location, an infiltrative appearance and without cystic-hemorrhagic components has rarely been described. We report on a 33-year-old woman with cyclic sciatica due to histologically documented infiltrative endometriosis involving the area of the left sciatic notch.
