Abstract:
A benign periosteal reaction, which can occur after trauma or stress, has a solid and uninterrupted appearance on radiography. In contrast, an aggressive periosteal reaction, which may indicate a malignancy, appears as a Codman's triangle or with a spiculated and sunburst pattern. In the present case, an 11-year-old boy with a previous injury to the distal radial growth plate presented with diffuse osteolysis on the distal radial metaphysis and decreased opacity of the lateral side cortex on plain radiograph. A Codman's triangle-like lesion was seen on the lateral side of the distal radius, and a few spicules were observed on the medial side of the distal radius. A T2-weighted coronal magnetic resonance image revealed a mass that had stripped the periosteum; the mass had heterogeneous signal intensity and a fl uid-fluid level on axial views. The margins of the mass were unclear, but enhanced. Suspecting a primary malignancy, we performed a biopsy. The pathology revealed that the mass was a simple hematoma.
