case_images: As the lower limb pain persisted after admission, an MRI scan of the hip joint was performed to evaluate the iliopsoas muscle, revealing inflammation in the left iliacus muscle (Figure 1A). A contrast-enhanced CT scan revealed pleural effusion and an abscess near the left ilium (Figure 1B), but there was no abscess on the iliopsoas muscle.
