This patient with a long psychiatric history was found to be eating a lot of hair and eventually starting vomiting.
CT shows a large mass completely distending the stomach consistent with a giant hairball based on the given history.
CT in the lung/air window shows a few tiny foci of air outside of the stomach (arrows), not where there should be any air at all. This is consistent with a small perforation of the stomach.
See here for another case of bezoar causing stomach obstruction.

Dang, I’d never considered this aspect of hair and bowel obstructions before.
You learn how all kinds of things, from the relatively mundane + bad luck to the weird and wacky, can cause serious health issues in radiology.
