Overview
CT scan may be helpful in the diagnosis of Riedel's thyroiditis. Findings on CT scan suggestive of Riedel's thyroiditis include hypodense infiltrative mass, invasion of nearby soft tissues, compression of the trachea, and esophageal compression.
CT scan
CT scan may be helpful in the diagnosis of Riedel's thyroiditis. Findings on CT scan suggestive of Riedel's thyroiditis include:[1][2]
- Hypodense infiltrative mass
- Invasion of nearby soft tissues
- Esophageal and tracheal compression
- Decreased contrast enhancement
