## Overview

[edit | edit source]

CT scan may be helpful in the diagnosis of bronchogenic cyst.

## CT

[edit | edit source]

CT scan may be helpful in the diagnosis of bronchogenic cyst. The density of bronchogenic cysts is variable from water density to high density due to blood, anthracotic pigment, increased calcium content, or increased protein content of the fluid.[1][2] Findings on CT scan suggestive of bronchogenic cyst is an

* Cysic mass with air-fluid levels[3]
* ovoid and well-defined encapsulated low-density cystic mass with no contrast enhancement.[4][5]
* Thin subtle walls
