(a) T1-weighted coronal image reveals areas of low signal intensity affecting the trapezium. (b) PD coronal image shows heterogeneous signal intensity with areas of high signal intensity. ((c) and (d)) STIR coronal and axial images reveal increased signal intensity affecting the whole trapezium consistent with hyperemic areas due to repair process and oedema.

T1-weighted MR images, the bone demonstrated low signal intensity while being hyperintense on PD and STIR sequences (Figure 1). The imaging findings were highly suggestive of early stage AVN of the trapezium.
After three months, an MRI scan reveals an almost normal trapezium with patient's symptoms fully subsided. (a) TIWI coronal image. (b) PD coronal image. ((c) and (d)) STIR coronal and axial images.
