The anteater nose sign refers to an anterior tubular elongation of the superior part of the anterior process of the calcaneus, which approaches or overlaps the navicular bone on a lateral radiograph of the foot. This fancifully resembles the nose of an anteater and is indicative of calcaneonavicular coalition ^1-3.

History and etymology

The anteater nose sign was first described by the American radiologist Alan E. Oestreich and colleagues in 1987 ¹.
