She had a non-reducible mass in the left lower abdomen that protruded more prominently on the application of abdominal pressure. Radiography (Picture 1) and computed tomography showed a hernia sac at the stomach (Picture 2), with a transitional zone in the abdominal defect (arrow) and gastric distension. Incarcerated Spigelian hernia of the stomach with gastric outlet obstruction was diagnosed. During the operation, the surgeon confirmed that the hernia had occurred between the meniscus and rectus muscle, and mesh repair was performed (asterisk, Picture 3).

We encountered an extremely rare stomach-type Spigelian hernia, and
