Pneumatosis cystoides intestinalis: a pathophysiologic explanation of the roentgenographic signs.
Pneumatosis intestinalis was first described by DuVernoi in 1730. The roentgenographic, gross, and microscopic apthologic changes are secondary to noncommunicating gas-filled cysts which occur either in submucosa or subserosa. The clinical findings, roentgenologic signs, and treatment are discussed. A differential diagnosis and pathophysiologic explanation for the changes are presented.
