Reason: thyroid nodule on left thyroid lobe seen on CT. RIGHT LOBE MEASUREMENTS: 5.0 x 1.6 x 1.5 cm.LEFT LOBE MEASUREMENTS: 4.4 x 1.3 x 1.5 cm.ISTHMUS MEASUREMENTS: Up to 0.35 cm in thickness.RIGHT LOBE: Normal background parenchymal echotexture without suspicious nodules.LEFT LOBE: Normal background parenchymal echotexture. Inferior pole nodule which appears to be within the thyroid gland measuring 1.5 x 1.3 x 1.3 cm and which is slightly hypoechoic, contains internal vascularity, and has a hypoechoic halo. Overall, this nodule is of intermediate suspicion for neoplasm. Alternatively but less likely, this nodule could be extrathyroidal.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: Few mildly prominent benign morphology left cervical lymph nodes, favor reactive.OTHER: No significant abnormality noted.
Left inferior pole nodule, probably within thyroid, of intermediate suspicion for neoplasm and which would be amenable to fine-needle aspiration. Correlation with patient's clinical history/laboratory values also recommended to exclude possibility of parathyroid adenoma, for which further evaluation with nuclear medicine scintigraphic imaging may be pursued if clinically indicated.
