Agenesis of The Thyroid Isthmus
Tiroid, vaskülaritesi yüksek bir endokrin bezdir. Sağ ve solda birer adet lobdan olusur ve istmus lobu her iki lobu birbirine bağlar ve H seklini andırır. Tiroid bezinin morfolojik varyasyonları ve gelisimsel anormallikleri literatürde genis bir yelpazede tanımlanmıstır. Sunumumuzda, 30 yasında kadın hastaya total tiroidektomi yapıldı. Operasyon süresince tiroidin sağ ve sol lobunun birbirinden bağımsız olduğu ve istmusun olmadığı görüldü. Tiroid istmus agenezisi olan bir vakayı sunacağız ve klinik önemi ve sıklığını tartısacağız.
Tiroid Istmus Agenezisi
The thyroid gland is an endocrine gland with high vascularise. It is formed of right and left two side lobes and of isthmus lobe joining the two lobes and this resemble the letter H. Morphological variation and developmental abnormalities of the thyroid gland has been reported in the literature in a wide range. In our report, total thyroidectomy was performed to a 30 year old woman. During the operation it was seen that the right and left thyroid lobe was independent from each other and isthmus lobe was absent. We will present a case of thyroid isthmus agenesis and discuss the clinical importance and the incidence of this case.
