Presentation
Right sided chest pain following minor trauma.
Patient Data
Age: 14
Gender: Female
From the case:
Rib enchondroma
Frontal

The lateral portion of the right 9th rib is expanded, but no definite fracture is seen.
From the case:
Rib enchondroma
Coronal bone window

Coronal bone algorithm slices from a limited chest CT demonstrate an expanded right 9th rib as seen on the CXR. There is cortical break laterally consistent with a pathological fracture.
Case Discussion
Features here are of a lucent rib lesion, with the top differential being a rib enchondroma although no pathological diagnosis was reached. Pain following minor trauma suggests pathological fracture through the lesion which was confirmed at CT.
