Radiograph and magnetic resonance imaging lunate fracture

The images of the right wrist are from a 25-year-old male who presented with wrist pain following trauma. The initial plain films were negative. Follow-up radiographs in the AP (A) and oblique (B) projections of the right wrist reveal a subacute nondisplaced fracture through the mid-portion of the lunate (highlighted in A and B). Subtle heterogeneity of the trabecular pattern is noted in A, while the fracture is obvious in image B. The T1 weighted MRI arthrogram in coronal projection (C) confirms the diagnosis of a subacute fracture (arrow).
