Analysis of the behavior and characteristics of thyroid lesions identified by biopsy fine needle aspiration and gammagraphic diagnosis: Hospital Calderon Guardia: period 2004-2006

Thyroid lesions have meant one of the most important pathological entities in the Costa Rican population for many years, which have been increased by new diagnostic examinations and early detection and timely thanks to the preventive medicine that is exerted on the security of the country. After the nuclear accident Chernobyl in the former Soviet Union for several decades ago has shown an increase in neoplastic lesions as well as was appreciated after the implementation of the first atomic bomb in World War II, this behavior is the interest to see how thyroid pathology develops in the environment and what have been the Costa Rican experiences in correlation with the expected time to the global statistics. The behavior pattern observed of the lessons of the thyroid gland and based on clinical findings and in some cases together with scintigraphy have allowed to study the development seen through the ultrasound and cytopathological result. The behavior of the patients was similar to global statistics, being most frequent the benign lesions than malignant, and the scintigraphy correlation with lesions were found to be cold was significant for determination of malignant or suspicious for malignancy. Some of these lesions that were suspicious for malignancy scintigraphy and ultrasound were benign have been found to fall within the expected rate for this type of injury. The study consisted of sampling in 2023 noted that the prevalence was 9:1 in women compared with men, which agrees as thyroid diseases are more common in women than in men as well as the expected results in malignant lesions that remained the same behavior. As expected in the age ranges of suffering from thyroid lesions remained between the fifth and sixth decade of life, which has allowed to observe the frequency of different benign and malignant lesions that occurred during this study in the decades and periods covered. While before the study of thyroid lesions was occupied by scintigraphy and endocrinological management has been viewed that incidentalomas appreciated by the teams high-resolution ultrasound bring a benefit in the care of the patient early and fast like its minimally invasive intervention to characterize the thyroid lesions that are suspicious of malignancy or indeterminate by clinical and other diagnostic methods, a fact that increases in the routine study of thyroid pathology. In fact in the cost benefit study of FNA for early patient care is relatively cheap with a great evaluation of lesions and is important for determination of injury, because if there were suspected, sonographically, it is easier to seek the consent from patient and treating physician to take the sample and lead to better clinical guidance, histological and radiological, fact that will allow the patient a concise definition of your case.
