The imaging findings support the diagnosis of Baxter neuropathy, in which the inferior calcaneal nerve is compressed resulting in denervation of either the m. abductor minimi or the m. quadratus plantae.

A probable explanation of the patient's story would be that a skiing trauma resulted in a fracture at the site of the intra-osseous lipoma, occult on the available images. The fracture healing may have compromised the inferior calcaneal nerve, e.g. by means of fibrosis, cortical irregularities or periosteal reaction, causing the now observed denervation.

However, as the patient did not exhibit typical clinical symptoms that could fit with Baxter neuropathy no treatment was indicated.
