Thyroid hemiagenesis: a case report

Abstract

Thyroid hemiagenesis is usually diagnosed incidentally during examination for other thyroid gland diseases. lodine-123 thyroid scan of a 25-year-old woman showed a normal homogeneous right thy­ roid lobe, but no uptake in the left lobe.Ultrasonography of the neck confirmed the absence of the left thyroid lobe, while the right lobe was homogeneous and normal. Thyroid hemiagenesis should be included in the differential diagnosis of thyroid diseases.

Tiroit hemiagenezi: Olgu sunumu

Abstract

Tiroid hemiagenezi, tiroit hastalıklarının ayırıcı tanı- sında hatırlanması gereken nadir bir hastalıktır. Ta- nı genellikle diğer tiroit hastalıklarına yönelik testler sırasında konmaktadır. Yirmi befl yaflındaki bir ka- dın hastanın iyot 123 tiroid sintigrafisinde sağ taraf- ta normal homojen tiroit lobu görünümü varken, sol lobda iyot tutulumu olmadığı gözlendi. Ultrasonog- rafi ile sol tiroit lobunun olmadığı doğrulanırken, sağ lobun tamamen normal, homojen görünümde olduğu gözlendi
