Case 04: Thyroid Nodule Ultrasound

Introduction:

Complex nodules are very common in thyroid gland and most of them are benign. Use of color Doppler along with 3D ultrasound aid in further evaluation.

Clinical Features:

23 years old female patient was sent for suspected thyromegaly.

Ultrasound Findings:

Right lobe is mildly enlarged with relatively normal left lobe & isthmus.
A well defined complex nodule containing both solid & cystic components (Predominantly cystic), is noted at the mid region of the right lobe.
Color Doppler shows a peripheral arterial supply with 28cm/s of PSV and 0.69 of RI. No internal vascularity.
Rest of the thyoid gland appears uniform.
No evidence of cervical lymphadenopathy or underlying muscle abnormality.

Images:

Features highly suggestive of:

Enlarged right lobe with complex nodule which is most likely benign.
However, FNAC correlation was advised for further evaluation.
