Figure 1 Diagnostic images from the magnetic resonance imaging examination. A: T1-weighted sagittal fast spin echo cross-section of the left foot; B: T2-weighted axial FSE cross-section, with the fracture site marked (orange arrow).

Figure 2 Diagnostic images from the magnetic resonance imaging examination. A: T1-weighted sagittal cross-section of the left foot; B: T1-weighted coronal cross-section, with the fracture site marked (orange arrow).

Figure 3 Diagnostic images from the computed tomography examination; sclerotic remodeling of bone tissue–orange arrow, very small cleft of the fracture–white arrow.

Figure 4 Diagnostic proton density weighted fat-suppressed (fs) axial images from the magnetic resonance imaging examination, with the fracture site marked (orange arrow).
