Can endometriosis spread to the brain?

Yes—endometriosis can occur outside the pelvis, and it has been reported in distant parts of the body. That said, brain involvement is extremely rare compared with pelvic disease or even other extra‑pelvic locations like the diaphragm and chest.

When people worry about “endo in the brain,” it’s often because they’re experiencing neurologic symptoms (headaches, nerve-type pain, numbness/weakness) that seem to flare with their cycle. Sometimes those symptoms are related to endometriosis affecting nerves or areas higher in the abdomen/chest rather than the brain itself, and the cyclical timing can be an important clue. If you have unusual symptoms that track with menstruation, our team can help you think through the full-body picture, determine what’s most likely, and map out next steps for accurate diagnosis and treatment—including minimally invasive excision when appropriate.
