Gastric lipoma is a location-specific subtype of gastrointestinal lipomas and represents a rare benign mesenchymal stomach tumor. 
​They are typically sessile in morphology, primarily solitary, and most frequently located in the gastric antrum, which may cause gastric outlet obstruction.

They can be definitively diagnosed on CT as well-defined, homogeneous fat-density lesions (-70 to -120 is diagnostic).
