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

Figure 17 T2-weighted fat suppressed, serial sagittal (A, B); T1-weighted, sagittal (C); T2-weighted fat suppressed, axial (D) and proton density-weighted, axial (E) show an elongated tubular cystic lesion (stars) along the posterior tibial nerve at the lower leg, ankle and foot. The lesion is seen within the substance of the nerve and has a central cystic component (stars) and a peripheral thin wall consistent with an abscess (D, E). This is a case of Hansen’s disease with posterior tibial nerve abscess; Ta: Talus; Ti: Tibia.
