Summary
Subacute thyroiditis diagnosis is improved by ultrasound, showing reduced blood flow in inflamed thyroid areas. This imaging technique aids in differentiating thyroiditis cases, enhancing diagnostic accuracy.
Area of Science:
- Endocrinology
- Radiology
- Pathology
Background:
- De Quervain's subacute thyroiditis presents with thyroid pain, fever, and inflammation markers.
- Transient hyperthyroidism and hypothyroidism can occur.
- Limited data exists on thyroid vascularity in this condition.
Purpose of the Study:
- To investigate thyroid vascularity in De Quervain's subacute thyroiditis using ultrasound.
- To assess the diagnostic utility of sonography and color Doppler in this condition.
Main Methods:
- Retrospective analysis of 21 patients with confirmed subacute thyroiditis.
- Utilized ultrasound with 7 and 12 MHz transducers, harmonic imaging, panorama imaging, and color Doppler.
- Clinical features, sonography, and cytology were analyzed.
Main Results:
- Thyroid structure was inhomogeneous with hypoechoic/nonechoic inflamed areas.
- Echogenic regions showed normal to increased vascularization.
- Inflamed areas exhibited reduced or absent blood flow on color Doppler, with normal peak systolic velocity in afferent arteries.
Conclusions:
- Sonography, combined with clinical data, diagnoses De Quervain's thyroiditis in over 90% of cases.
- Color Doppler sonography is valuable for differential diagnosis in ambiguous cases.
