Figure 7

Coronal T2 weighted fat suppressed image of the left shoulder obtained approximately 1 year and 9 months since the initial presentation shows image findings consistent with avascular necrosis of the left humeral head. In this image, the classic double line sign with inner T2 hyperintensity and outer T2 hypointensity for osteonecrosis is well depicted.
