ABSTRACT
Introduction: The gland thyroid cancer (GTC) is relatively infrequent. Ultrasound is a useful tool for its diagnosis. It is important to know the ecographic characteristics of a nodule thyroid (NT) that is associated more frequently with cancer. Most of the cases have good forecast after surgical resection.
Aim: To analyze the graphic-ultrasound characteristics of the GTC‘s patients of our institution and to do a world literature´s review on the topic.
Material and method: We made a review of the clinic and radiologic records of 81 pacients with TGC´s diagnostic confirmed by hitopatology in a five years period. Two Radiologists assigned to the ultrasound section took to end the scrutiny of the studies and there was realized the statistical analysis of the obtained information.
Also there was done an exhaustive review of the world literature on the topic.
Results: It was more frequent in women (86 %), in the group of age of between 31 and 59 years (62 %), of histological type papilar (91 %) and from minor size to 3 cm (54 %). The predominant ecographic characteristics were these: solid nodule (70 %), hipoecoic (46 %), with microcalcifications (47 %) and hipoecoic halo (72 %).
Discussion: The results of our study do not differ in a significant way with the reported in the world literature, just in the fact that there wasn’t predilection for the groups of age of less than 30 and any more than 60 years.
Conclusion: The finds of this review are similar to the reported in the literature. The characteristics of biggest importance and more frequently finded were the solid composition of the nodule, its hipoecogenicity and the presence of microcalcifications.
