Gastric lipoma

Dr Henry Knipe et al.

Gastric lipomas are a location-specific subtype of gastrointestinal lipomas and represent a rare benign mesenchymal tumours of the stomach. They can be definitively diagnosed on CT. 

Gastric lipomas are rare, accounting for <5% of gastrointestinal lipomas and <1% of all gastric neoplasms 2

Patients may present with pain, upper gastrointestinal bleeding, dyspepsia and/or gastric outlet obstruction, although they are typically asymptomatic when small. 

Gastric lipomas are typically sessile in morphology, solitary (75%) and most frequently located in the gastric antrum. They tend to be submucosal rather than subserosal. Gastric ulceration is common. 

Gastric lipomas are composed of mature adipose cells surrounded by a fibrous capsule. 

Features are non-specific on upper gastrointestinal contrast studies with filling defects and a central bulls-eye, reflecting ulceration common 2,3

Gastric lipomas present as well-defined, homogenous fat-density lesions (-70 to -120 is diagnostic) 2.
