====== Femoral intraneural ganglion cyst ======
[[Ganglion cyst]]s affecting nerve are rare causes of neuropathy. The formation of [[intraneural ganglion cyst]]s, once controversial, has recently been clarified. 

Lovaglio et al. described the first modern description of a femoral intraneural ganglion cyst at the [[hip]] region.

A patient presented with a 1 year history of radiating pain, [[quadriceps muscle]] weakness and anteromedial leg numbness was found to have a femoral intraneural cyst with a hip joint connection on MRI.

Surgical disconnection of the articular branch led to improvement of the [[neuropathy]] and resolution of the cyst on postoperative MRI.

The unifying articular (synovial) theory describes the joint origin of [[intraneural ganglion cyst]]s, even when they occur in unusual locations, and their propagation into the parent nerve. Knowledge of this theory can improve outcomes; surgery needs to address the joint origin or capsulolabral defect lest recurrence ensue
