Pneumatosis is rare in this agegroup. In non-neonate pediatrics, the causes include (from a series of 30 patients 1):
non-infective colitis (32%)
enteric infection (27%)
In this case, there was no evidence of infection or dysmotility. Lactate was normal. The child responded to steroid therapy and a presumed diagnosis of non-infective colitis was made. The cause was no identified and there were no further presentations.
