Enchondroma occurs in bone formed by cartilage and are solitary, eccentric, non-expansile or expansile lesion sometimes detected incidentally. 

Differentials include bone infarcts and chondrosarcoma. Infarcts are densely sclerotic with serpiginous border, whereas chondrosarcoma depends more on clinical features and is difficult to differentiate from enchondroma radiologically.

While reporting, more importance should be given to looking for aggressive features as they can warrant surgery.
