Abstract

Introduction


Ectopic thyroid is a  rare  congenital  condition.  Dual ectopic  thyroid  is  rarer still with  only  30  cases  reported  in  literature.  The  most  common  location  is  the  lingual  or  sublingual  region  followed  by  the  hyoid  region.  Instances  of  dual  ectopic  thyroid  with  one  in  lingual  region  and  the  other  in  mediastinum  are very few.


Case  Report


A  case  of  dual  ectopic  thyroid is presented with  absent  normal  thyroid  in  a  girl  of  14  years  who  presented  with  difficulty  in  swallowing  and  lump  sensation  in  throat.  Ultrasound,  MRI  scan  and  Technetium  99m  pertechnetate  thyroid  scan  were  done.  She  showed  lingual  thyroid  and  thyroid  tissue  in  upper  mediastinum  and  no  thyroid  tissue  in  the  normal  anatomical  location. 


Discussion


The  discovery  of  mediastinal  ectopic  thyroid  was  incidental.  She  had  subclinical  hypothyroidism  and  was  treated  with  thyroxine  replacement  therapy.
