Divergent results for presence of full thickness cartilage defects on MRI and CTA. In case (a) a full thickness cartilage defect at the talus was suggested on MRI; CTA revealed depression of the cartilage surface but no full thickness defect. In case (b) no cartilage defect was suggested on MRI but due to massive bone marrow edema at the tibia CTA was performed and revealed a fissural full thickness defect at the tibia.
