Overview
Overview
CT scan may be helpful in the diagnosis and fully characterizing the extent of substernal goitre. Findings on CT scan suggestive of multinodular goiter include enlarged and heterogeneous thyroid gland. CT scan is useful in defining the extent of tracheal deviation and compression. CT scan–guided fine needle aspiration biopsy(FNAB) may be helpful.

- Neck CT scan may be helpful in the diagnosis and fully characterizing the extent of substernal or nonpalpable goitre.[1]
- Findings on CT scan of neck suggestive of multinodular goiter include enlarged and heterogeneous thyroid gland.
- CT scan is useful in defining the extent of tracheal deviation and compression.
- Following CT scan with iodinated contrast, patients with underlying nontoxic multinodular goiter may develop thyrotoxicosis due to iodine load(Jod-Basedow effect).
- CT scan–guided fine needle aspiration biopsy(FNAB) may be helpful in diagnosis of multinodular goiter.
- PET scan with 18F-fluorodeoxyglucose can be done although it offers no additional diagnostic benefit in the evaluation of a thyroid nodule.[2]
