Gastrointestinal stromal tumors are the most common nonepithelial tumors of the gastrointestinal tract. The stomach is the most common site of occurrence. Most of the tumors are asymptomatic. Many patients may present with mass per abdomen, gastrointestinal bleed. Tumors arising from the stomach’s posterior wall may grow large, and on imaging, it may create confusion of the site of origin. We present a case of gastrointestinal stromal tumor arising from the stomach’s posterior wall, growing large and creating a confusion of site of origin.
