Large Colloid Cystic Nodule of Thyroid: Ultrasound Findings Ultrasound Findings: Anechoic or fluid-filled cystic center: This appears black on the ultrasound image. Peripheral hyperechoic rim: The surrounding thyroid tissue is brighter than the cyst. Lobulated margins: The edges of the cyst are irregular or bumpy. Abundant freely floating echogenic foci: These are seen as bright dots or streaks within the cyst, likely representing colloid material. These may produce characteristic comet-tail artifacts due to acoustic shadowing. Multinodular goiter: Presence of multiple nodules within the thyroid gland. for more visit: https://www.ultrasound-images.com/thy... Differential Diagnoses: Follicular thyroid carcinoma: Requires further evaluation if the nodule demonstrates: Microcalcifications (tiny bright flecks) within the cyst Increased vascularity on Doppler ultrasound Hemorrhagic thyroid cyst: May appear similar but with internal echoes due to blood products within the cyst. Branchial cleft cyst: Less common, but may appear cystic in the neck and require differentiation. Prognosis: Large colloid cystic nodules with the described features are typically benign. Risk of malignancy is low, but follow-up is recommended. Management: Reassurance and monitoring: Most cases can be managed with observation using serial ultrasound exams to monitor for any changes in size or characteristics. Fine-needle aspiration (FNA): If features raise suspicion for malignancy, a biopsy with FNA may be recommended for definitive diagnosis. Surgery: In rare cases, if the cyst causes significant cosmetic concern, compressive symptoms, or indeterminate cytology on FNA, surgical removal may be considered. Additional Notes:nd helps
