MRI shows T1 phase with gadolinium contrast, showing a small superficial gluteal collection joining large deep subcutaneous collections in contact with the muscular fascia, associated with diffuse infiltration of the neighbouring subcutaneous tissue and the gluteus maximus muscles.

MRI showed a large subcutaneous collection of 4 x 7 x 10 cm in contact with the muscular fascia, associated with a diffuse infiltration of the neighbouring subcutaneous tissue, the gluteus maximus muscle, and the presence of an ipsilateral inflammation of the sacroiliac joint (Figure 1).

Drains were progressively removed and daily dressings were replaced by intermittent negative-pressure wound-therapy at postoperative day eight for four weeks (Figure 2).
At six months' follow-up, a hyperpigmented scar of a three-centimeter diameter was present in the middle of a depressed area of about seven centimetres in the right gluteal region. The scar is not hidden in a conventional swimming suit.

There is obvious gluteal asymmetry compared to the contralateral side (Figure 3).
