case_images: Axial, T2 weighted, fat saturated, STIR MR image showing loculated fluid signal within the tibialis posterior muscle (thick white arrows), suggestive of a collection. Also noted are diffuse T2 hyperintense signal changes in the surrounding musculature (thin white arrows), compatible with myositis.

case_images: fig1
case_images: Imaging (MRI) of the left lower limb was performed. It showed a multiloculated collection with enhancing rim and septa centered within the tibialis posterior muscle, measuring approximately 13.9 x 4.4 x 4 cm with adjacent myositis and fasciitis (Figures 1, 2, 3, 4, and 5).
case_images: Coronal, T2 weighted, fat saturated, STIR MR image showing loculated fluid signal within the tibialis posterior muscle (thick white arrows), suggestive of a collection. Also noted are diffuse T2 hyperintense signal changes in the surrounding musculature (thin white arrows), compatible with myositis.
