Gastric lipoma is a rare benign tumor of the stomach. The imaging characteristics are diagnostic because the lesion has fat attenuation on computed tomography and demonstrates characteristics of fat on magnetic resonance images. On ultrasound, the lesion can be identified as a lesion hypoechoic to the gastric mucosa that is soft, but the mass cannot be displaced with compression. Identifying these imaging characteristics can prevent biopsy or surgery in asymptomatic patients. Although this lesion is benign, it can cause gastric obstruction.
