Systemic lupus erythematosus (SLE): an unusual cause of ileocolic intussusception

Intussusception is a rare diagnosis in adults. Gastrointestinal involvement is not unusual in systemic lupus erythematosus (SLE).¹ A case of intussusception as first presenting symptom of SLE is described. A 50-year-old woman of Chinese origin came to the emergency room with symptoms of high fever, nausea, vomiting and weight loss of 10 kg. Three months before, an episode with abdominal pain due to ileal invagination in the colon occurred. Laboratory analysis showed: thrombocytopaenia, lymphopaenia, positive antinuclear antibody, antidouble-stranded DNA, Coombs tests and low C3 in combination with an active urine sediment and proteinuria. CT and positron emission tomography scan showed lymphadenopathy, but no other abnormalities. Axillar lymph node biopsy showed no abnormalities. The diagnosis new-onset SLE was made. Prednisone treatment was started and soon thereafter tapered, azathioprine and hydroxychloroquine were added. During follow-up, the SLE remained in remission. SLE is a rare cause of ileocolic intussusception and ileocolic intussusception may be the first presenting symptom.
