Man 52 yo, voice tone changes for  2 months, and  ENT doctor said vocal
paralysis by endoscopy.
Ultrasound of the neck    
US1  left thyroid lobe normal
US2  right  lobe 
 covered by a big mass  4 cm  with strong  posterior shadowing 
cannot see structure inside.
US3  near R/ CCA  small nodes with calcification #1cm.
US4  with convex probe ultrasound cannot se intra tumor by
very strong calcification.
MTSC  non CE   
CT1: cross- section of the neck = mass is  very high calcification 
CT2 : cross- section=  calcification some lymph nodes
near R/  CCA.
CT3 : frontal view  with CE=HU of this mass is  1,319
UI
CT4:   lymph node also has HU  1326UI.
CT5:  sagittal view 
 this mass  is  covered near the righ lobe of thyroid gland.
Blood test   TSH  is  0,041  T4  1,2 
 TG  97,42 (  n 3, 5-77)
 Pre-op diagnosis is thyroid cancer  metastasis neck lymph nodes.
OPERATION REMOVED RIGHT THYROID GLAND AND LYMPHADENECTOMY.

 For this case  clinical  ultrasound and CT , blood
tests suggested   thyroid carcinoma   but report  of FNA 
cytology is negative.
CALCITONINE = 2PG/ML   (M <18.2PG/ML)..RULES OUT MTC ( MEDULLARY THYROID CARCINOMA)
