case_images: Ultrasound scan targeted on the thigh demonstrates some loss of definition of the normal muscular striations on the right side (red arrow), with an increase in generalized edema, particularly subcutaneous edema (blue arrow).. Note: The left side was also scanned, which demonstrates the normal linear striations expected within skeletal muscle (green arrow).

case_images: Targeted ultrasound of both thighs (Figure 1) was undertaken to exclude a muscle tear, or the presence of infection with abscess formation.
case_images: Coronal T1 (non-fat saturated) MRI scan demonstrates right sided muscular swelling combined with subtle loss of the intramuscular fat striations (red arrow) when compared with the contralateral side (blue arrow).. Abbreviation: MRI, magnetic resonance imaging.

case_images: A coronal T1 (non-fat saturated) scan, without contrast, demonstrated right-sided muscle swelling combined with a subtle loss of intramuscular fat striations (red arrow) when compared with the contralateral side (blue arrow) (Figure 2).
case_images: Axial STIR image demonstrates extensive T2 hyperintensity in the right thigh musculature, in keeping with extensive edema.. Notes: Most notably, the right vastus medialis (VM) muscle is affected (red arrow). Adjacent musculature is affected to a lesser extent. Extensive subcutaneous edema noted (blue arrow). The left side is also affected with similar edema, though to a much lesser extent, mainly affecting the vastus lateralis (VL) (green arrow) and a degree of adjacent subcutaneous edema (yellow arrow).

case_images: The left side primarily involved the vastus lateralis muscle (green arrow) and had accompanying subcutaneous edema (yellow arrow) (Figure 3). The sagittal STIR image confirmed edema in the right vastus medialis (red arrow) (Figure 4).
