Gastric Teratoma in an Adult Female Patient: A Case Report

Background: Gastric teratoma (GT) occurs as a rule in infancy and is an extremely unusual gastric tumor in adult patients. Case Presentation: In this paper, we present the clinical and imaging findings of a 56-year-old female patient with a GT. The patient's main symptoms were increasing abdominal discomfort and pain. After the physical examination, she underwent ultrasound (US) and computed tomography (CT), which showed a large mass at the posterior wall of the stomach, and a teratoma was initially considered. After surgery, pathology confirmed the diagnosis of GT. The patient recovered after surgery and was discharged in good health. To the best of our knowledge, this study is the first reported case of gastric teratoma in an adult woman in the literature. Conclusion: astric teratoma of the adult period is a rare benign neoplasm that may have several complications; therefore, imaging is crucial for diagnosis and accurate treatment management. The aim of this study is to emphasize the value of US and CT in the diagnosis and treatment monitoring of mature gastric teratomas.
