31 Perforated Neonatal Appendicitis Mimicking Necrotizing Enterocolitis in a Premature Neonate: A Case Report and Literature Review

Year: 2025

Type: article

Abstract: Necrotizing enterocolitis (NEC) predominantly affects preterm infants and can mimic other conditions like acute appendicitis. Neonatal appendicitis (NA) is extremely rare, with an incidence of 0.04% to 0.2% and high fatality rates. Due to its rarity and resemblance to other neonatal conditions, NA diagnosis is often delayed. We report a case of a 2220-gram male preterm neonate delivered at 31+5 weeks via urgent cesarean section due to chorioamnionitis, initially misdiagnosed with NEC but later found to have a perforated appendix. The neonate recovered well post-surgery, with the ileostomy reversed 10 weeks later. Prompt surgical intervention is crucial for NA, as it requires different management than NEC. This case underscores the importance of considering NA in preterm infants with severe abdominal symptoms and emphasizes timely surgical intervention to improve outcomes. Additionally, it supports the hypothesis that localized NEC involving the appendix may have a better prognosis than generalized NEC.
