Cystic lesions of peripheral nerves: Are we missing the diagnosis of the intraneural ganglion cyst?

Figure 9 Image A-D show serial, T2-weighted, fast spin echo axial sections of the left hip joint highlighting a cyst (star) at the level of the left sciatic notch. An extension along the expected course of the articular branch of the sciatic nerve (white arrows) communicating with the posteromedial aspect of the ipsilateral hip joint (open arrows) is also seen.
