Background: Diabetes mellitus is associated with increased incidence of thyroid abnormalities, including thyroid nodules and gland enlargement, compared to healthy individuals. Some of these nodules can be malignant. Ultrasound is a valuable tool in assessing the thyroid gland, for such parenchymal abnormalities. We assessed by means of ultrasound, the incidence of thyroid nodules and other parenchymal changes in diabetic patients, and compare same with apparently healthy controls. Materials and Methods: One hundred and twenty adult diabetic patients and an equal number of apparently healthy adults were sonographically examined. In each subject, both lobes of the gland were scanned with a 5-12 MHz linear array transducer of a Sonoace ultrasound scanner. The thyroid was examined for nodules and other parenchymal abnormalities. Results: Thyroid nodules were noted in both diabetic and control groups. Both male and female diabetic patients had significantly greater number of thyroid nodules compared to controls; 18 male diabetics or 34.6% against 2 male controls or 4.5%; P = 0.001 and 22 female diabetics or 32% against 13 females controls or 17%; P = 0.033. Gender did not influence the detection of thyroid nodules among diabetics. Conclusion: Diabetic patients have higher frequency of thyroid nodules compared to apparently healthy individuals. It is recommended that the nodules be subjected to further imaging studies/biopsy for possibility of malignancies.
