Presentation transcript:

A 46-year-old woman with a history of attempted right tarsal tunnel release presented with persistent foot and ankle pain with numbness in the medial plantar distribution. A 46-year-old woman with a history of attempted right tarsal tunnel release presented with persistent foot and ankle pain with numbness in the medial plantar distribution. A and B, Sequential sagittal T2 SPACE images demonstrate a spindle-shaped NIC involving the distal tibial nerve (long arrows). Notice the attenuated appearance of the medial (short arrows) and lateral (wavy arrow) plantar nerves. C, Intraoperative photo confirmed the NIC (long arrow) and small proximal medial and lateral plantar nerves entrapped in scarring (short arrow). D, Extensive neurolysis was performed and a nerve wrap was placed. Follow-up sagittal T2 SPACE MR image shows the wrap as a hypointense covering around the tibial and proximal medial plantar nerve (curved arrow), with residual hyperintensity of the nerves. A.
