Chondroblastoma of the calcaneus: radiographic features with emphasis on location

Fourteen cases of chondroblastoma of the calcaneus have been examined and the radiographic features described. Thirteen occured in males. In all but one case the location was either at the talocalcaneal articulation or adjacent to the posterior calcaneal cortex. A sclerotic margin was present in all instances. Occasionally calcifications and septations were seen.
