First presentation of a Nora-lesion of the talus in a paraossal fasciitis

Nora-Lesion is a proliferation that normally develops out of an intact corticalis. The entity of this fibroostotic pseudotumor, as discussed in literature, is triggered from repeating trauma or reactive periosteitis. In the literature, there are more than 200 cases defined as Nora lesion. In the daily routine of medical offices or ambulances, the Nora- Lesion should be established as a differential diagnosis for a swelling of the foot. Our case report of a 49-year-old patient is the worldwide first description of a Nora lesion of the talus, as well as secondary of the calcaneus. In the immense differential diagnosis discussion for bony pathologies of the hindfoot the Nora-lesion should be now added.
