Limited access to advanced imaging in many parts of Nigeria has contributed to missed or delayed diagnosis of some rare conditions. This case report highlights an incidental finding of a gastric diverticulum during post-treatment surveillance in a breast cancer patient and thus underscores the diagnostic value of imaging in resource-limited settings. A 51-year-old woman undergoing post- treatment surveillance for left breast cancer had a contrast-enhanced whole body CT scan, which showed no metastatic disease but revealed a 2.5 cm air- and fluid-filled outpouching arising from the posterior gastric fundus, consistent with a gastric diverticulum. The patient remained asymptomatic. Conservative management was recommended, including dietary modifications, optimization of glycemic control, and follow-up with endoscopy if symptoms developed. Gastric diverticula are rare, and can be seen incidentally on CT where they may mimic renal or adrenal pathologies. This case presents a possible diagnostic pitfall, one that emphasizes the value of imaging in detecting incidental findings with potential clinical relevance.
