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.

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).
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.
