Background/Aim:
The aim of this study was to determine the natural history of benign thyroid nodules using ultrasonography.
Patients And Methods:
The records of 223 patients with benign thyroid nodules treated at the Kochi Medical School from 2010 to 2012 were reviewed retrospectively. Repeated ultrasonography was performed, and the findings were directly compared with previous images.
Results:
The median change in the size of the nodules was 0.01 cm/year, although the size of six nodules (2.7%) increased more than 0.5 cm/year, and these nodules were removed surgically. Nineteen patients (8.5%) underwent surgery during the follow-up period. Compared to those who did not undergo surgery, the size of the nodules was larger and the rate of change in nodule diameter was higher in those undergoing surgery. The pathological diagnosis based on repeated fine needle aspiration cytology was benign nodules in 16 patients and papillary cancer in three patients.
Conclusion:
Even if a thyroid nodule is initially diagnosed as benign, it may have malignant potential. Therefore, so as not to miss malignancies, nodules should be carefully re-evaluated to assess their growth or change in size using ultrasonography.

01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
