MRI findings of sciatic endometriosis

Area of Science:

• Neurology
• Gynecology
• Radiology

Background:

• Endometriosis is a condition where uterine-like tissue grows outside the uterus.
• Sciatic mononeuropathy, or dysfunction of the sciatic nerve, can have various causes.
• This case explores a rare presentation of endometriosis impacting the sciatic nerve.

Observation:

• A woman presented with cyclical hip pain related to menstruation.
• Symptoms included right leg weakness and sensory loss, indicative of sciatic nerve involvement.
• Physical and electrodiagnostic examinations supported sciatic nerve dysfunction.

Findings:

• Magnetic resonance imaging (MRI) revealed abnormal signals near the right sciatic nerve.
• These signals were consistent with endometriotic tissue.
• The abnormal signals showed partial regression following endometriosis treatment.

Implications:

• This case highlights endometriosis as a rare cause of sciatic mononeuropathy.
• It demonstrates the diagnostic value of MRI in identifying pelvic disorders.
• Early diagnosis and treatment can potentially alleviate neurological symptoms associated with endometriosis.
