Overview
Thyroid ultrasonography is the imaging method of choice in the diagnosis of multinodular goiter. Findings on an ultrasonography suggestive of multinodular goiter include more than one nodule including the non-palpable nodules cysts with varying echogenicity. Thyroid ultrasonography helps in assessment of size and number of nodules. Assessment of vascular characteristics of a thyroid nodule with Doppler helps in screening thyroid nodules for malignancy.
Ultrasound
- Thyroid ultrasonography is the imaging method of choice in the diagnosis of multinodular goiter.
- Findings on an ultrasonography suggestive of multinodular goiter include more than one nodule including the non-palpable nodules cysts with varying echogenicity.[1]
- Thyroid ultrasonography helps in assessment of size and number of nodules. Surgeon-performed ultrasonographic examinations can be used to make necessary changes in surgical treatment and to avoid unnecessary surgery.[2]
- Assessment of vascular characteristics of a thyroid nodule with Doppler helps in screening thyroid nodules for malignancy.
- Findings on ultrasonography suggestive of multinodular goiter benign nodules include:[3]
- Iso-hyperechoic nodules
- Surrounding hypoechoic halo
- Spongelike/honeycomb pattern
- Peripheral (eggshell) or coarse calcifications.
- Doppler:
- Peripheral vessels are usually noted
- The risk of malignancy is lower in nodules with a predominantly perinodular pattern
- Findings on ultrasonography suggestive of multinodular goiter malignant nodules include:[3]
- Hypoechoic solid
- Intranodular blood flow.
- Presence of microcalcifications
- Size greater than 10mm
- Nodules with an exclusively central vascular pattern on doppler
- It is important to screen for presence of malignant features (if any) and futher investigate with fine needle aspiration biopsy(FNAB) from the suspicious nodule.
- Thyroid ultrasonography can be used to guide FNAB. ultrasonography-guided FNAB may be preferable to palpation-guided FNAB.
- The possibility of measuring thyroid volume is another highly useful feature of ultrasonographic studies particularly after therapy with L-T4 or radioiodine ablation
