22-year-old man with a history of anterior calcaneal fracture by prior MRI. Evaluate healing.IMAGE ACQUISITIONS: Unenhanced CT of the right ankle with multiplanar reformatting. There is mild diffuse demineralization, consistent with disuse osteopenia. No definite fracture is apparent by CT imaging. No sclerotic lesions are present within the calcaneus, and there is no evidence of cortical thickening or periosteal reaction to suggest an underlying lesion. No displaced fracture.Incidental note is made of a well corticated os trigonum. The remainder of the visualized osseous structures are unremarkable. The joint spaces are well preserved, with no evidence of dislocation or degenerative change.There is mild indistinctness in the fat planes surrounding the peroneal tendons, which is consistent with the reactive tenosynovitis seen on the prior MRI study. No additional focal soft tissue abnormalities are appreciated.
Findings consistent with disuse osteopenia, however, otherwise, no acute abnormalities are appreciated by CT exam. Please see the prior MRI study for further details.
