Computed tomography imaging diagnosis of the left rib chondromyxoid fibroma: A case report

Chondromyxoid fibroma is a rare benign bone tumor. The etiology of chondromyxoid fibroma is still unknown. We report a case of a 26-year-old male who suffered from chronic cough for a year. His chest radiograph showed a lobulated tumor over the left seventh rib. The computed tomography (CT) examination further revealed an osteolytic tumor arising from the left seventh rib with calcified matrix, incomplete marginal calcifications and cortical destruction. He underwent surgical resection of this tumor. The pathologic diagnosis was chondromyxoid fibroma.
