Large osteochondroma. Plain radiographs. Anteroposterior (a) and lateral view (b) demonstrate a large sessile osteochondroma (thick arrow) at the lateral aspect of the right tibia. There is obvious scalloping (arrow) and slight posterior displacement of the fibula, in keeping with a slow-growing lesion. Coronal fat-suppressed T2-WI (c) shows a hyperintense cartilage cap with partially mineralised hypointense cartilage and an intralesional cystic component (arrow). The maximum cartilage thickness is 16 mm. Axial T1-WI (d) shows the posterior displacement of the common peroneal nerve with a preserved fascicular structure (thick arrow)
