A member asked:

Can tarlov cysts at s2-3 be definitively diagnosed by pelvic mri? if not, what is the differential diagnosis and follow up?

Usually can be seen: In a lumbar spine mri, pelvic MRI could also be used, but it is typically noted as an incidental finding on a lumbar spine mri. Most of the time it is not symptomatic. See a neurosurgeon or spinal specialist.

Tarlov cysts: Tarlov cysts are typically outpouching cysts of the spinal canal and contain spinal fluid found typically in the sacrum. Mri of the pelvis and sacrum can diagnose their existence. Sometimes lumbar spine MRI will also demonstrate their existence if study goes down to sacrum.

Yes: A tarlov cyst is probably generative bulging of the dura typically causing slow erosion of the sacrum. They can be seen on a pelvic mr. The key point is that the vast, vast majority need no treatment and are present in 10-20% of people above the age of 50.
