Abstract

Pneumatosis cystoides intestinalis (PCI) is an uncommon condition characterized by the presence of a collection of individual gas cysts in the submucosa and subserosa of the intestine. The etiology of PCI is still unclear. We experienced 3 cases with PCI during treatment for pulmonary Mycobacterium avium complex (MAC) infection. Each case was treated conservatively. We believe our case series will highlight the importance of examining the gastrointestinal tract of patients with MAC infection and hopefully elucidate the clinical characteristics of PCI which developed during MAC treatment.
