Background and Objective: Thyroid nodules (TNs) are abnormal growths of thyroid cells that form masses within the thyroid gland. TNs are common, and the importance lies in need to exclude thyroid cancer. This study was intended to evaluate the diagnostic accuracy of ultrasonography for differentiating benign from malignant thyroid lesions in comparison with fine-needle aspiration cytology (FNA cytology). Methods: This study involved 133 patients with thyroid lesions. All patients underwent thyroid ultrasonography and ultrasound (US)-guided-FNA cytology and results were compared. Results: Out of 133 patients included in this study, the mean age was 41.2±15 years, and 113 (85%) were female. Thyroid lesions were benign in 126 cases (94.7%) and malignant in nine cases (5.3%). Among 124 patients with thyroid lesions diagnosed as benign with US, 122 (98.38%) were confirmed to be benign with FNA cytology, and only 2 (1.6%) were proved to be malignant. Among nine patients with thyroid lesions diagnosed as malignant by US, 5 (55.6%) were confirmed to be malignant by FNA cytology, and 4 (44.4%) were proved to be benign. The US diagnosed benign thyroid lesions with a sensitivity, specificity, positive predictive value, and negative predictive value of 98.38%, 71.42%, 98.38%, and 55.55%, respectively. The results revealed strong compatibility between diagnosis of benign thyroid lesions by the US and proved diagnosis by FNA cytology (p<0.001). Conclusion: B-mode ultrasonography is a valuable tool in differentiating benign from malignant thyroid lesions. It can almost always predict the benign nature of thyroid lesions with excellent diagnostic accuracy. doi: https://doi.org/10.12669/pjms.35.3.292 How to cite this:Alshoabi SA, Binnuhaid AA.

“…14,28,30,31 Of course, some studies are in agreement with our results, which showed a higher rate of sensitivity such as Xu et al,2017, 32 moreover, microcalcification was associated with malignancy (97.0%) and benign (3.0%), but there were conflicting data about absent, eggshell, coarse, and macrocalcification such as studies published from Petrone et al, 2012, Kim et al, 2013, and Park et al, 2014. 33-35 A study by Koike et al, 2001, 36 indicated that calcification had a sensitivity of 88.7% and Ram et al, 2015 showed a high sensitivity (80%) and a relatively lower specificity (68%) for calcification, 19 results of these two studies are relatively close to our findings for calcification (both micro as well as macro). On the other hand, our data have clearly demonstrated that taller than wider shape was the other predicting feature of malignancy with high sensitivity but low specificity.…”

“…These results were in contrast with Kwak et al, 2011, Ram et al, 2015, and Wang et al, 2017, and also, consistent with, Ren et al, 2015, Nabahati et al, 2019 and Moon et al, 2011, who demonstrated a taller-than-wide shape can be of a good help in predicting malignant nodules. 19,37-40 Our results revealed that difference between isoechoic nodules (0.0%), hypoechoic nodules (91.5%) and hyperchoic nodules (7.8%), was statistically significant, the research by Degirmenci et al, 41 reported the hypoechoic nodules (35.9%), isoechoic nodule (28.6%) or hyperechoic nodules (33.3%) were no different in number. The study by Leenhardt et al, 42 showed the hypoechoic and isoechoic nodules (20% and 21%, respectively) compared with hyperechoic nodules (7%).…”

The purpose of research was comparing the ultrasound (US) features and fine-needle aspiration cytology (FNAC) in detecting the thyroid nodules in clinical practice. A cross-sectional analytical study retrospectively reviewed the US and FNAC findings for a total of 170 thyroid nodules. The US features that we compared included echogenicity, calcifications, shape, halo and Doppler, between 2017 and 2018. Totally, 170 nodules of thyroid were studied, which contained 72 (42.4%) benign and 98 (57.6%) malignant thyroid nodules. The sonographic features were significantly associated with malignancy such as microcalcification (97.0%), hyperechogenicity (91.5%), wider than taller shape (98.0%), absent halo (90.9%) and positive Doppler (78.0%) (P < 0.01). The altogether accuracies of calcification, echogenicity, shape, halo, and Doppler were 0.96, 0.92, 0.97,0.82 and 0.82, respectively. Our data suggest that US features could be a good sonographic criterion for recommending FNA cytology with follow‐up thyroid sonography and FNA.

“…Esto muestra que la histología de los nódulos diagnosticados en estos pacientes es mayormente de carácter benigno. El estudio Diagnostic validity of ultrasonography in thyroid nodules, del doctor Islam et al 14 , en el año 2015, expone que, en una población de 101 pacientes, el 95% de la histología de los nódulos diagnosticados fue benigna, y solo el 4.9% fue maligna.…”

ResumenLa Enfermedad Nodular Tiroidea (ENT) es motivo de frecuente consulta médica, por lo que debe ser evaluada con precisión para realizar un tratamiento adecuado, en el momento preciso. Esta afecta entre el 4-7% de la población, siendo las mujeres las más propensas a presentar la enfermedad.Determinamos la frecuencia de Enfermedad Nodular Tiroidea en los pacientes que asisten al servicio de endocrinología en un hospital de Santo Domingo, República Dominicana, durante el período febrero-abril de 2016, en un estudio de carácter retrospectivo, descriptivo y de corte transversal. Evaluamos 206 archivos médicos y sonografías de los pacientes diagnosticados con Enfermedad Nodular Tiroidea.El 96% de los pacientes, equivalente a 197 casos de los nódulos tiroideos, se presentan en mujeres, mientras que solo un 4%, igual a 9 casos, fueron identificados en hombres. La aparición de nódulos se incrementa entre los rangos de edad de 50-60 años y disminuye significativamente al superar los 60 años de edad. Predominan los coloides y quistes simples, según el tipo histológico de los nódulos, con una aparición muy poco frecuente de carcinomas.Palabras clave: Enfermedad Nodular Tiroidea; edad; sexo; histopatología. SummaryNodular Thyroid Disease is a reason for frequent medical consultation, so it must be evaluated accurately to perform an appropriate treatment, at the right time. This affects between 4-7% of the population, with women being more likely to have this disease.We determined the frequency of Nodular Thyroid Disease in patients attending the endocrinology service in a hospital in Santo Domingo, Dominican Republic, during the period February-April 2016, in a retrospective, descriptive and cross-sectional study. We evaluated 206 medical records and sonograms of patients diagnosed with Nodular Thyroid Disease.The 96%, equivalent to 197 cases of thyroid nodules, occur in women, while only 4%, equivalent to 9 cases, were identified in men. The appearance of nodules increases between the age ranges of 50-60 years, and decreases significantly after reaching 60 years of age. Colloids and simple cysts predominate according to the histological type of the nodules, with a very rare occurrence of carcinomas.
