Pseudocyst and a collar stud abscess: new face of necrotizing enterocolitis.

Meconium pseudocyst formation secondary to antenatal perforation is well described. We present a preterm infant who had intra-abdominal pseudocyst formation following postnatal intestinal perforation secondary to necrotizing enterocolitis (NEC) and secondarily leading to extra-abdominal collar stud abscess. This is new face of NEC and this presentation has not been reported earlier.
