Typical causes of infection in Crohn's disease (CD) patients include intra-abdominal abscess, microperforation of the intestine, and fistula formation. Use of immunosuppressive drugs and abdominal surgery are often associated with CD sepsis. In this case, an 11-year-old boy who did not receive any concomitant treatment was admitted for evaluation owing to weight loss. On the 22nd day of hospitalization, he suddenly experienced a septic shock and was admitted to the intensive care unit (ICU). Enterobacter cloacae was detected in the blood culture. No findings as to the source of the intra-abdominal infection were present. The patient was treated with antibiotics, ventilator management, circulatory management with massive intravenous fluids and vasoactive agents, and blood purification therapy. Suspecting the presence of CD based on weight loss and a history of perianal abscess two years prior, a lower gastrointestinal endoscopy was performed. The results revealed a longitudinal ulcer with skip lesions. His general condition was stabilized, and he was extubated on the seventh day in the ICU. He subsequently began treatment for CD in the general pediatric ward. In conclusion, when a sepsis on account of the intra-abdominal infection is suspected, but the infection focus is not evident and the immunosuppressive background is unclear, CD should be considered. Doing so will ensure that sepsis and CD are treated appropriately.
