ABSTRACT
Objectives: To provide a specific diagnostic print based on the ecographic characteristics of the thyroid nodules. To publish the casuistry of benign and malign nodules in our hospital center.Material and methods: An ultrasound and Fine needle aspiration biopsy (FNAB) was carried out, in 18 to 55 yearsold female patients who presented palpable thyroid nodules and non palpable thyroid nodules in patients with inherited background of thyroid cancer, in the period between March 1 to August 31, 2008.
Results: 72 patients were included in this study, who were classified in two groups: those that presented nodules of benign ecographic characteristics (46) and those that presented nodules of malign ecographic characteristics (26); both groups were submitted to FNAB, later on, the definitive cytological result was correlated with the ultrasonographic result, finding in this last one, a sensibility of 96%, a specificity of 76%, a positive predictive value of 46% and a negative of 98%. The characterization of the nodules was carried out mainly due to its ecogenicity degree, size, calcifications, and vascularity and if an association of cervical adenopathies existed.
Analysis: The result of our work coincides with that of other researchers who point out the hypoechoic nodule like suspect of malignancy. Garrete et al, report that 79% of the malign lesions of the thyroid (carcinomas) were of hypoechoic nature.
Conclusions: It was determined that the solid hyper or isoechogenic and mixed thyroid nodules (with cystic component) with thick calcifications were benign and those solid, hypoechogenic, with fine calcifications, associated to cervical adenopathies were related to thyroid cancer.
