Perforated jejunal GIST after blunt abdominal trauma: a case report

We present a rare case of perforated jejunal gastrointestinal stromal tumour (GIST) following minor blunt abdominal trauma. Small bowel GISTs are uncommon entities, and presentation with acute perforation and generalized peritonitis is particularly rare, especially in the absence of prior diagnosis or significant inciting trauma. A 40-year-old male presented with an acute abdomen and clinical peritonitis consistent with a perforated viscus. Laboratory evaluation revealed significant leukocytosis, and cross-sectional imaging demonstrated pneumoperitoneum, prompting urgent surgical intervention. Given the combined clinical, radiologic, and laboratory findings, the patient underwent emergent exploratory laparotomy with segmental small bowel resection. This case highlights an uncommon presentation of jejunal GIST and underscores the importance of prompt recognition of peritonitis, timely operative management, and early multidisciplinary oncologic evaluation following definitive surgical treatment.
