Abstract
OBJECTIVE: To describe the first reported case of pneumatosis intestinalis (PI) in a pediatric patient with granulomatosis with polyangiitis (GPA) and multiple other risk factors and review the literature for PI in adult and pediatric rheumatologic conditions. METHODS: A PubMed search was completed using the search phrase "pneumatosis intestinalis." Searches were limited to humans and the English language, and remaining articles involving patients with rheumatologic diagnoses were identified and included in our discussion. RESULTS: This is the first reported of case of PI in a patient with underlying GPA or antineutrophil cytoplasmic antibody-associated vasculitides. Out of 90 previously reported cases of PI in patients with rheumatologic conditions, 79 cases were in adults and 11 in children. There were 30 patients with systemic sclerosis, 18 with MCTD/overlap syndrome, 18 with dermatomyositis or polymyositis, 16 with SLE, and 8 with other diagnoses. Overall, 81% of the patients were on corticosteroids or other immunosuppressants prior to development of PI. The most common presenting symptom was abdominal pain, and 51% of patients had associated pneumoperitoneum. CONCLUSIONS: PI can be associated with a broad spectrum of rheumatic diseases, including GPA, and should be included in the differential diagnosis of patients with rheumatologic conditions and nonspecific gastrointestinal symptoms.
