[Ischemic colitis: an uncommon manifestation in systemic lupus erythematosus].

We present the case of an adolescent with ischemic colitis, an infrequent pathology in this age group, worsened in the presence of systemic lupus erythematosus (SLE). The patient, aged 20, was diagnosed SLE at 6. She consulted for fever, abdominal pain in the side and right iliac fossa and diarrhea lasting 48 hours. It was assumed as acute gastroenteritis but given the persistent pain, incoercible vomiting and abdominal distension she was hospitalized. The abdominal X-ray showed distended loops, abundant feces, without air-fluid levels. The ultrasound showed erosions and ulcerations, edema and bleeding in the descending colon submucosal layer. The CT scan evidenced an ischemic lesion in the right colon. Ischemic colitis is a severe condition, infrequent in young individuals. Signs, symptoms, abdominal CT scan and colonoscopy are the elements of choice for the diagnosis.
