Hypothyroidism signs and symptoms. In another radiology center multiple nodules reported and FNA was recommended.

Patient Data

Age: 33
Gender: Female

Thyroid ultrasound and colour Doppler

Pseudonodular appearance: Multiple hyperechoic nodular appearances are consist of fibrosis and coarse hypoechoic areas are consist of lymphocytic infiltrates.

Power Doppler and colour Doppler modes show that hypoechoic areas are more vascular than hyperechoic areas.

Case Discussion

Characteristic ultrasound features are highly specific for Hashimoto's disease. Pseudonodular appearance is one of them and hyperechoic areas represents parenchymal fibrosis.

Awareness of this features may prevent patients from unnecessary FNAC.
