case_images: (A) Plain CT showed an extensive low-density area in the subcutaneous soft tissues of the low lumbar and the left buttocks extending caudally to the left lower thigh and the right greater trochanter (asterisks). (B) Contrast-enhanced CT showed an encapsulated, subcutaneous lesion in the subcutaneous soft tissues of the low lumbar and the left buttocks extending caudally to the left lower thigh and the right greater trochanter (asterisks). (C) MRI showed an encapsulated, abnormal-intensity lesion (asterisks) and a partial injury to the muscles of the buttocks (white arrow). MRI coronal STIR shows no fat suppression.

case_images: Plain CT showed an extensive low-density area in the subcutaneous soft tissues of the low lumbar and the left buttocks extending caudally to the left lower thigh and the right greater trochanter (asterisks) (Figure 1A), a finding consistent with a MLL. However, contrast-enhanced CT on day 47 showed an encapsulated, subcutaneous lesion in the same area (asterisks) (Figure 1B). MRI coronal STIR shows no fat suppression (Figure 1C). T2-weighted images and STIR appeared hyperintense, and T1-weighted images not appeared hyperintense (Figure 1C). Treatment was based on clinical symptoms, lesion size, severity, age, and co-morbidities.
