Posterior gastric perforation which opens into transverse mesocolon is even rarer. This is a case report done to entail such a rare case, with only two cases reported in the past. We present the case of a 21-year-old female with pain in the epigastric region spreading to involve the whole abdomen, fever, vomiting, and anorexia. In our case, radiological findings revealed pneumoperitoneum. Intraoperatively, a tract was identified between the posterior wall of the stomach and transverse mesocolon. Tract was excised and primary repair was done using the Graham patch method.
