“…26,27 Thyroid nodules incidentally detected by ultrasound performed for carotid or parathyroid disease have a risk of malignancy of approximately 10%. [24][25][26][27][28][29][30][31][32][33][34][35][36][37] Such nodules should undergo dedicated thyroid sonographic evaluation. Lesions with a maximum diameter Ͼ1.0 cm to 1.5 cm should undergo FNA, unless they are simple cysts or septated cysts with no solid elements.…”

“…Because recent guidelines recommend that all pa-tients with palpable nodules undergo ultrasound examination, 6,8,34,38 an increasing number of biopsies are now being performed with ultrasound guidance. Published data indicate that ultrasound evaluation and ultrasound guidance reduce the rate of nondiagnostic specimens and false-negative aspirates.…”

In the adult population, thyroid nodules are common and are increasingly detected by ultrasound examination or other scanning techniques. Depending on their size and ultrasonographic features, these nodules may require further investigation, including tissue diagnosis. Fine-needle aspiration (FNA) has become the predominant method to obtain tissue for microscopic analysis. In October 2007, the National Cancer Institute sponsored a conference to review the state of the science for the use of FNA in the management of thyroid nodules. This conference reviewed indications for thyroid FNA and pre-FNA requirements, training and credentialing, techniques for thyroid FNA, diagnostic terminology and morphologic criteria, utilization of ancillary studies, and post-FNA testing and treatment options. The results of those discussions have been published in both print and electronic versions. The aim of the current article was to discuss indications for FNA, diagnostic terminology, and post-FNA options, issues that are important to physicians who are managing patients with thyroid nodules.

 Carotid duplex -7% 3  USG neck -2% -15% 5  CT scan -4% -11% 6  PET Scan -30% -40%. 4,7,8 Solid thyroid nodules more than 1 cm in size should undergo ultrasound-guided fine-needle aspiration biopsy according to American Thyroid Association guidelines. Consideration for biopsy of thyroid nodules less than 1 cm should be restricted to nodules with atypical USG characteristics and potential nodules that are positive on PET scan due to their higher rate of malignancy. ABSTRACTBackground: Incidental thyroid nodules are typically non-palpable thyroid nodules found during radiographic evaluation for a non-thyroid related issue (USG neck, CT scan, PET scan, carotid duplex).The prevalence of thyroid incidentalomas ranges from 1.6% to 67% based on radiographic modality of detection. The rate of malignancy in incidental thyroid nodule can again quite variable based on how it was discovered and range from 4% to 50%. (The overall risk is approximately 15%).

“…Twothirds of cancers found are localized to the dominant nodule with the remaining cancers localized to the nondominant nodule. Liebeskind et al found that thyroid nodules discovered incidentally by ultrasound had a significantly higher risk of malignancy than those that were nonincidental (17% vs. 3%; p=0.20) [4].…”
