[Asymptomatic pneumatosis cystoides intestinalis in a patient with systemic lupus erythematosus].

ABSTRACT

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by the presence of gas-filled cysts in the submucosa or subserosa of gastrointestinal tract. PCI has been widely recognized as a late manifestation of systemic sclerosis but seldom reported to take place in patients with systemic lupus erythematosus (SLE). We reported here a 13-year-old female who had been diagnosed to have SLE based on the following findings; malar rash, discoid erythema, proteinuria, positive antinuclear antibody and anti-DNA antibody. She had been treated with various immunosuppressive drugs including pulse use of corticosteroid, cyclophosphamide and cyclosporin A. She was referred to our hospital because of proteinuria and numbness on her right fifth toe, refractory to above treatment. On admission, the activity of her disease was already low and she had no abdominal symptoms. Plain X-ray film showed multiple round translucencies along the wall of the ascending and transverse colon. Colonoscopy revealed multiple firm-walled cysts distributing in the terminal ileum as well. A diagnosis of PCI was made and she was successfully treated with oral antibiotics and laxatives. The association of PCI with SLE is reviewed briefly.
