Follicular and papillary thyroid carcinoma status post resection. Outside ultrasound suggests worrisome lesion right thyroid bed RIGHT LOBE: Status post thyroidectomy. Vague hyperechoic region and right thyroid bed without increased vascularity unchanged from 11/1/2013.LEFT LOBE: Status post thyroidectomy. Subcentimeter hypoechoic foci within the left thyroid bed. The largest measures 0.8 x 0.3 x 0.7 cm. Given differences in transducer acquisition parameters, it is unclear whether not these foci have significantly changed from the prior studies.ISTHMUS: Status post thyroidectomyPARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No regional adenopathy.OTHER: No significant abnormality noted.
Status post thyroidectomy. Echogenic focus within the right thyroid bed unchanged from 2013; favor benign etiology such as scar. Accordingly, no biopsy was performed.Subcentimeter hypoechoic foci within left thyroid bed. Given differences in transducer acquisition parameters, it is unclear whether not these foci have significantly changed from prior studies. While these may represent benign residual thyroid tissue, would recommend follow-up scan in 4 months to document temporal stability.
