Pneumatosis intestinalis and diarrhea in a child following renal transplantation *

Abstract: Pneumatosis intestinalis is an uncommon finding beyond the neonatal period, but it has been reported in immunocompromized pediatric patients. The association of pneumatosis intestinalis in children following renal transplantation has to the best of our knowledge been only reported once in children. We describe a 4‐year‐old female who developed intermittent emesis, weight loss, and intermittently loose bloody stools after cadaveric renal transplantation at age 3.5 years. An abdominal x‐ray demonstrated extensive pneumatosis in the colon. The infectious work‐up was negative. Histologically, she had increased eosinophils throughout the lamina propria in the rectum. A glucose breath test was suggestive of small bowel bacterial overgrowth. She was treated with 10 days of metronidazole with resolution of the diarrhea and occult blood in stools. One month after the treatment she had radiologic resolution of her pneumatosis. Based on this report, pneumatosis intestinalis should be considered in the differential diagnosis of children after organ transplant suffering from diarrhea, abdominal pain, or blood in the stool.
