The left lobe is normal. Although the lesion in the right lobe is solid hypoechoic and ill defined biopsy in this case proved this to be a granulomatous inflammation without any signs of malignancy

Both cases show some uncommon pathology of the thyroid gland. In these cases the definitive diagnosis could only be made through a biopsy procedure
