CTICasesTraumatic Thyroid Hematoma
Imaging findings
CT of the neck in a blunt trauma patient demonstrates asymmetric enlargement and hypo-enhancement of the left thyroid lobe. Non-contrast imaging shows hyperdensity within the expanded lobe, and a repeat CTA four days later shows near-complete resolution and normal thyroid appearance.
Key takeaways
Direct blunt trauma to the neck can cause a thyroid contusion or intra-thyroidal hematoma. On emergency contrast-enhanced CT, it presents as an expanded, hypo-enhancing thyroid lobe, but typically resolves rapidly and spontaneously without requiring surgical intervention.
