Multiple Tarlov cysts at S2-3 level with bone remodeling and compression to the cauda equina roots.
Tarlov cysts are benign perineural cysts, typically occurring in the lower lumbar and sacral spine, usually seen at the existing foramina arising from exiting nerve roots. They are more common in females. These benign cysts are usually asymptomatic, however sometimes they can grow to a large size and cause pressure symptoms and bone remodeling as in this patient.
