[Thyroid incidentaloma frequency in a university hospital]

The prevalence of thyroid incidentaloma is variable and always created the dilemma of how to manage them. The objective was to determine the frequency of thyroid incidentalomas in a University Hospital.

A descriptive, transversal, prospective study was done; a non-probabilistic sample was used with patients who met the following criteria: >18 years, indiscriminate sex, and an image that included neck: ultrasound, computed tomography and/or magnetic resonance. Patients with known or suspected thyroid nodule or any other thyroid disease and pregnant women were excluded. Descriptive statistics were used.

153 patients who had the criterion; 11 patients had an incidentaloma (7.18%). Females were more frequent with seven cases (63.6%), the mean age was 56.9 years. Morphologically only a single thyroid nodule was detected. The nodules were smaller than 1.5 cm.

The prevalence documented in our study is smaller than other reports, it is proposed monitoring patients with thyroid incidentalomas according to current consensus guidelines.
