Abstract
RATIONALE: Gastrointestinal stromal tumor (GIST) arising in Meckel's diverticulum represents a rare condition; tumor enlargement may result in intestinal obstruction and perforation. Previous case reports have documented atypical imaging features associated with this pathology. PATIENT CONCERNS: We report a case involving a 67-year-old male patient with intestinal obstruction and perforation secondary to a GIST located within a Meckel's diverticulum. DIAGNOSES: The patient was diagnosed with malignant GISTs within Meckel's diverticulum, complicated by perforation and intestinal obstruction. INTERVENTIONS: Computed tomography imaging clearly displays the imaging features of Meckel's diverticulum tumor and its complications. OUTCOMES AND LESSONS: Computed tomography imaging clearly delineated a cystic protrusion corresponding to Meckel's diverticulum, identified the tumor boundary within the diverticulum, and visualized the supplying vascular structures as well as the imaging features associated with complications such as obstruction and perforation. This detailed diagnostic approach facilitates prompt and precise diagnosis, thereby enabling the development of timely and targeted treatment strategies.
