Homogeneity Parameter in Contrast-Enhanced Ultrasound Imaging Improves the Classification of Abnormal Cervical Lymph Node after Thyroidectomy in Patients with Papillary Thyroid Carcinoma

Figure 3

Forty-one-year-old man had received left thyroidectomy four years ago. ACLNs were detected on the left neck one year ago. (a) ACLN located in level IV: loss of fatty hilum, microcalcification, and hyperechogenicity in conventional US (15 × 7 mm). A normal hilar (Type II) pattern is shown. Notice: right lower edge of LN showed hypoechogenicity. (b) Heterogeneous hyperenhancement on CEUS (19 s after SonoVue injection). Notice: right lower edge of LN showed hypoenhancement.) (c) Needle was inserted in ACLN, and FNA diagnosis was metastatic PTC. (d) This CLNM was filled with cancerous thyroid tissue under optical microscopy, and normal lymph tissues still exist in the edge of LN.
