Findings: Figure 1-2:
1. A small round wound in midline of buttock, above to anus.
2. Relative increased hairs near wound.
3. Reddish skin of lower back.

Figure 3-9:
1. Eextensive fluid accumulation with internal heterogeneous
   signal intensity and peripheral contrast enhancement in
   subcutaneous tissue of abdominal wall, chiefly in lower back,
   between superficial fatty layer (Camper fascia) and
   deep membranous layer (Scarpa fascia), with T5 cranial
   dissection and coccyx caudal extension, in favor of abscess
   with small hemorrhage or gas formation.
2. Small long T1 and T2 signals with contrast enhancement in
   subcutaneous tissue of coccygeal region, compatible with
   infectious fistula track.
3. Although there is no direct MR evidence, the subcutaneous abscess
   may secondarily come from a coccygeal dermal sinus tract
   (a potential repeated infectious source).
Diagnosis: Abdominal wall abscess possibly secondary from dermal sinus tract infection
