Endometriosis is a common condition that mostly affects people assigned as female at birth. The most clinical symptom of endometriosis pain. Although the mechanism for this pain poorly understood, in some cases, nerves are directly involved endometriosis. multifocal disease, and pelvis location involved. Nerves can become entrapped Pelvic visible pelvic MRI, especially when imaging planes sequences tailored neural evaluation. In particular, high-spatial-resolution anatomic including three-dimensional isotropic contrast-enhanced short inversion time inversion-recovery (STIR) fast spin-echo useful nerve imaging. commonly sciatic, obturator, femoral, pudendal, inferior hypogastric lumbosacral plexuses. it thought to be rare, true incidence involvement not known. Symptoms include pain, weakness, numbness, incontinence, paraplegia may constant or cyclic (catamenial). Early diagnosis important prevent irreversible damage chronic sensorimotor neuropathy.
