--------------------------------------------------------------------------------------
Diagnostic category Risk of malignancy (%) Usual management
--------------------------------------------------------------------------------------
I. Insufficient for Diagnosis 1-4% Repeat FNA with ultrasound guidance
II. Benign <1% Clinical follow-up
III.Atypia of Undetermined significance 5-15% Repeat FNA
IV. Suspicious for Follicular Neoplasm 15-30% Surgical, as clinically indicated
V. Suspicious for Malignancy 60-75% Surgical, as clinically indicated
VI. Malignant 97-99% Surgical, as clinically indicated
