Abstract

Myositis Ossificans (MO) is a benign lesion in which bone tissue forms within muscle or soft tissue after a traumatic injury. It most commonly occurs in the extremities, large muscle groups and demographically in young adults, with a higher incidence in women. 60–75% of cases are associated with trauma. To achieve an accurate diagnosis of suspected soft tissue lesions, different imaging methods need to be evaluated. In cases where imaging findings are insufficient, biopsy may be required for histopathological confirmation. This case report aims to emphasize the following: 18F-Fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) should be considered in the differential diagnosis of soft tissue tumors, the diagnostic importance of the CT component in 18F–FDG PET-CT, and the crucial role of a detailed medical history in reaching a diagnosis.
