-Follicular often indeterminate due to difficulty telling follicular carcinomas from follicular adenomas on FNA.
-Need vascular/capsular invasion to diagnose follicular carcinoma.
-If benign, follow up clinically w/ serial US.-L
-Thyroxine not recommended.
-If increasing in size, reexamine w/ FNA.
-Eval is same in pregnancy but no radionucleotide scans are done. If differentiated cancer found can delay surgery until post delivery.
