Radiographically Occult and Subtle Fractures: A Pictorial Review
Figure 11
Stress fracture of the right radius in a 40-year-old man, a semiprofessional billiard player, with no history of trauma and complaining of pain of the right forearm for one month. (a) Anteroposterior radiograph shows medial radial cortex periosteal reaction (arrow) but no fracture line is seen. (b) Coronal reformatted CT depicts monocortical fracture line through the periosteal thickening (arrowheads). (c) Coronal T2-weighted fat-suppressed MRI shows intramedullary hyperintensity within the bone marrow (arrow) corresponding to bone marrow edema.
