Introduction. Gastrointestinal duplications are rare congenitalanomalies, especially in the adult population which
can occur along the entire gastrointestinal tract. The rarest
among them are gastric duplications, making up 2–8% of all
gastrointestinal duplications. Unusual embryonic malformations
can be found even in the adult population and should
always be considered in the differential diagnosis of thoraco-
abdominal tumors. Unclear findings during preoperative
diagnostic procedures are the reason for presenting the
case. Case report. We present a 33 years old female, with
tumorous lesion in the stomach wall, which had the endoscopic
ultrasound features of gastrointestinal stromal tumor.
During surgery, it was determined that the lesion was actually
a cystic formation with gelatin content and histological
examination confirmed the diagnosis of gastric duplication
cyst. Conclusion. Preoperative diagnosis of gastric duplication
cyst has always been a challenge for clinicians, since its
morphological appearance may vary. That is the reason why
these anomalies are often misdiagnosed as solid tumorous
lesions by imaging methods and even by the most superior
ones, and set up the surgery as a part of diagnostic algorithm.
