Objective: Thyroid ultrasound plays a major role in the clinical management of patients with thyroid nodules. Comprehensive reporting enables malignant risk stratification and biopsy decisions. In this study, we aimed at a systematic evaluation of the content and completeness of thyroid radiology reports. Methods: A retrospective study was undertaken. A total of 200 thyroid ultrasound reports of examinations performed over a 1-year period were reviewed. After excluding 18 reports, the remaining 182 were evaluated for the inclusion of the following nodule characteristics: size, 3-axis dimensions, location, presence or absence of five signs suspicious of malignancy, namely microcalcification, hypoechogenecity, irregular margin, height-to-width ratio, and intranodular vascularity. Results: While all reported nodules could be stratified easily as being more or less than 1 cm in size, only 23.6% of these nodules were reported in 3 dimensions, and 33.5% of the nodules were specifically localized. For any described nodule, the frequency of reporting on echogenicity was 50%, on vascularity 19.2%, on margin 10.4%, on calcifications 9.3%, and no report contained a description of the height-to-width ratio. The cumulative frequency of reporting on one characteristic per nodule was 84%, of two characteristics 27%, three characteristics 4.4%, and no report included ≥4 characteristics per nodule. Conclusion: Despite easily accessible templates, reporting of thyroid nodule sonogram continues to be incomplete and inconsistent. This in turn constitutes a waste of a significant tool that could otherwise help in making timely informed medical decisions and in providing a significant platform for patients’ future follow-up.

Abstract Introduction: Prevalence of thyroid nodules in the adult population based on detection by ultrasonography is about 20-76% of which only 5% account for thyroid cancer. All patients with a suspected thyroid nodule either on physical examination or noted incidentally on other imaging should be evaluated with thyroid ultrasound. Any thyroid nodule >= 1 cm on ultrasound should be investigated with FNAC. Ultrasound guided FNAC techniques are used to reduce false negative results. We present a patient with suspicious finding on initial thyroid ultrasound and subsequent negative FNAC presenting a few years later with papillary thyroid cancer. Case Presentation: A 32 y.o. female with history of thyroid nodule and thyroiditis presented to the endocrine clinic for follow-up of her thyroid nodule. 5 years ago, she was diagnosed with thyroid nodule, which was found on an ultrasound scan for workup of her dysphagia. The thyroid ultrasound then showed diffusely heterogeneous thyroid gland with an ill-defined area of decreased echogenicity in the right lobe and left superior lobe and possible nodule in the lower pole left thyroid. Blood work showed TSH of 1.71 (n 0.34-3.00 uIU/ml) and thyroid peroxidase antibody levels was 27.8 (n < 9.0 IU/ml). A CT scan of neck with contrast was done and no concerning mass was seen. The patient had a follow-up ultrasound after 8 months which showed small bilateral thyroid lesions, somewhat ill-defined. The patient had an FNA biopsy of the right thyroid nodule: the results were consistent with a benign follicular nodule. A follow-up thyroid ultrasound was done in a year, and the findings were unchanged. The patient came back 3 years later for follow-up with complaints of a new palpable nodule in the neck. Ultrasound showed unchanged right thyroid nodule and some new cervical adenopathy. The ultrasound showed a 2.2 cm heterogeneous lymph node with punctate echogenic foci along the right lateral margin of the right internal jugular vein at the level of the thyroid gland, Subsequently FNA biopsy of the right cervical node and right thyroid node were done. The cells from lymph nodes were positive for malignancy and cells from the right thyroid nodule were atypical. Overall the appearance was consistent with papillary thyroid carcinoma. Subsequently the patient underwent total thyroidectomy and right modified lymph node dissection and the pathology results came back as multifocal papillary thyroid cancer right side 1.2 cm and left side 0.4 cm, with metastasis to 2 lymph nodes. Conclusion: The reported false negative rate of ultrasound-guided FNAC is variable. Success of US-FNA depends on experience of operator and cyto-pathologist and the intrinsic nature of the nodule. Malignancy rates of only 1-2% are reported with repeat FNA in prior benign nodules. Good FNA techniques and real-time visualization of needle in target nodules can further decrease false negatives.

Objective: Laser Ablation (LA) is a therapeutic modality for reducing the volume of large benign thyroid nodules. This retrospective study was aimed at assessing the outcome of LA in patients with benign nonfunctioning thyroid nodules in a 5-years follow-up. Methods: Sixty-two patients (47 females; mean age 54.7±12 yr) with benign cold thyroid nodules underwent LA from July 2009 to March 2012. Nodule volume, thyroid function test, and ultrasound were monitored at baseline, and at 3, 6 and 12 months after the procedure, then annually. After dividing nodules in solid and spongiform, we evaluated unfavourable outcomes: 1) nodule’s volume reduction <50%; 2) need for surgery; 3) need for additive LA session (due to nodule re-growth with persistence of cosmetic concern or compressive symptoms). Results: Baseline volume did not differ between solid and spongiform nodules as well as energy delivered and the number of needles used. Unfavourable outcomes occurred in 24 patients (38.7%). Nineteen/ 24 (79.2%) patients who experienced unfavourable outcomes belonged to the solid nodules group (P<0.01). When considering only those who benefited from LA, the 5-years reduction was 59.7% for solid and 78.6% for spongiform nodules (P<0.05). One/6 patients who underwent surgery (solid nodules group) had a final diagnosis of Follicular Variant of Papillary Thyroid Cancer (FVPTC). Conclusion: Large solid nodules, unlike spongiform, submitted to LA are characterized by a long-term unfavourable outcome and entail a potential risk of false negative cytologic results.

In 1974 we began a prospective study of a cohort of 4296 individuals exposed to therapeutic head and neck irradiation during childhood for benign conditions. To define the role of thyroid ultrasonography in following irradiated individuals, we studied a subgroup of 54 individuals. They all had been screened between 1974–1976 and had normal thyroid scans and no palpable nodules at that time. Thyroid ultrasonography, thyroid scanning, physical examination, and serum thyroglobulin measurements were performed. One or more discrete ultrasound-detected nodules were present in 47 of 54 (87%) subjects. There were a total of 157 nodules, 40 of which were 1.0 cm or larger in largest dimension. These 40 nodules occurred in 28 (52%) of the subjects. Thirty (75%) of these 1.0-cm or larger nodules matched discrete areas of diminished uptake on corresponding thyroid scans. The 10 that did not match (false negative scans for ≥1.0-cm nodules) were the only nodules of this size in 7 subjects. Of 11 nodules 1.5 cm or larger, only 5 were palpable. Serum thyroglobulin correlated to the number (P = 0.04; r2 = 0.10), but not the volume of the thyroid nodules (P = 0.07; r2 = 0.08). We conclude that thyroid nodules are continuing to occur and are exceedingly common in this irradiated cohort of individuals. The results confirm that thyroid ultrasonography is more sensitive than physical examination and scanning. However, thyroid ultrasound is so sensitive and nodules so prevalent that great caution is needed in interpreting the results.

Abstract Background Thyroid nodule diagnosis has become increasingly frequent. Defining optimum surveillance intervals for patients with unsuspicious thyroid nodules remains a challenge. This was a single centre cohort study in which patients diagnosed with unsuspicious thyroid nodules in whom no treatment was indicated were invited for re-evaluation 5 years after the diagnosis. The primary end point of the study was to estimate the change in nodule size with thyroid ultrasound (US) and the secondary end point was to assess the need for clinical management 5 years after the diagnosis. Patients and methods Baseline patient parameters and ultrasound characteristics of the nodules were retrospectively collected. At follow-up, thyroid ultrasound was performed. Results A hundred and eighteen (107 women / 11 men, aged 56.8 ± 13.4 years) patients were included in the study having 203 nodules at baseline, with mean largest nodule diameter 10.5 ± 7.4 mm. After 5 years, 58 (28.6%) nodules significantly increased in size, 27 (13.3%) decreased, and for 104 (51.2%) of nodules, no change in size was noted. Fourteen (6.9%) nodules disappeared. Additional 26 new nodules (mean largest diameter 7.7 ± 5.0 mm) in 16 patients were identified at follow-up. Regarding the clinical outcome, no new thyroid cancers were found. For 107 (90.7%) patients no further management was indicated. Five (4.2%) patients were referred to thyroidectomy because of the growth of the nodules. Two (1.7%) patients were treated for hyperthyroidism. Four (3.4%) patients did not complete the study. Conclusions We report a single centre experience of the natural history of unsuspicious thyroid nodules. Our results showed that 71.4% of such nodules remained stable in size, decreased or even disappeared and that the vast majority of the patients remained clinically stable with no need for treatment 5 years after the diagnosis.
