Tarsal coalitions are relatively rare diagnoses affecting adolescent patients that typically present with progressive foot pain. Cuboid-navicular coalition, a type of tarsal coalition, is extremely rare with less than 10 reported cases to date. Most prevailing theories reported have described this specific type of coalition as asymptomatic except at specific moments of stress and exercise. The purpose in presenting this case is to demonstrate that cuboid-navicular coalition can be associated with chronic unremitting pain, as in our patient. We present a case of cuboid-navicular fibrocartilaginous coalition in an adolescent patient presenting with chronic foot pain. Furthermore, from an imaging standpoint, radiographic findings are often subtle and radiologists cannot rely on indirect signs such as talar beak in clinching the diagnosis of cuboid-navicular coalition. Instead, abnormal articulation between the cuboid and navicular must be sought.

Radiomics is a quantitative approach to medical image analysis targeted at deciphering the morphologic and functional features of a lesion. Radiomic methods can be applied across various malignant conditions to identify tumor phenotype characteristics in the images that correlate with their likelihood of survival, as well as their association with the underlying biology. Identifying this set of characteristic features, called tumor signature, holds tremendous value in predicting the behavior and progression of cancer, which in turn has the potential to predict its response to various therapeutic options. We discuss the technical challenges encountered in the application of radiomics, in terms of methodology, workflow integration, and user experience, that need to be addressed to harness its true potential.
