The 3D visualization reveals a primary tumour classified as T2, showing a neoplasm measuring greater than 2 cm but not exceeding 4 cm in greatest dimension, confined to the thyroid gland without evidence of extrathyroidal extension. The model emphasizes the larger tumour size compared to T1 lesions, highlighting the expansile growth within the thyroid parenchyma and the potential for compression of adjacent structures such as the trachea, oesophagus, or recurrent laryngeal nerve, while the absence of gross local invasion maintains the tumour within the intermediate prognostic category, warranting consideration of total thyroidectomy and closer postoperative surveillance.
