Abstract

Objective: The aim of this study is to investigate the presence of pyramidal lobe in thyroid scintigraphy and to compare the presence of pyramidal lobe in different thyroid pathologies between genders. Methods: Images of 866 patients (663 female, 203 male) with ages ranging from 8 to 85 were evaluated retrospectively. Presence of pyramidal lobe and its location were established in images. Patients were divided into groups in terms of gender, presence of nodular/ diffuse goiter, thyroid function test results and rate of the presence of pyramidal lobe and whether a significant difference existed between the groups were calculated. Results: Of the 866 patients, 156 (18%) had pyramidal lobe observed in scintigraphy. Hundred and 26 (81%) of patients observed to have pyramidal lobe were female and 30 (19%) were male. Pyramidal lob stemmed from the left lobe in 76 (48%) patients, right lobe in 61 (40%) patients, and isthmus in 19 (12%) patients. Pyramidal lobe visualization rate was 18% for euthyroidism and hyperthyroidism, it was found as 15% for hypothyroidism. The rate of pyramidal lobe visualization was 13% in nodular goiter patients, 43% in diffuse goiter patients, and 20% in patients whose scintigraphy showed normal thyroid glands. In the statistical evaluation, rate of pyramidal lobe visualization in diffuse goiter patients was found to be significantly higher compared to other patients (p<0.001). Conclusion: Preoperative imaging of pyramidal lobe especially in patients requiring total thyroidectomy would decrease relapses that may occur later and thus facilitate the treatment and monitoring of patients.

Özet

Amaç: Çalışmamızda amaç, tiroid sintigrafisinde piramidal lob varlığını araştırmak ve piramidal lob varlığının farklı tiroid patolojilerinde, cinsiyetler arasında karşılaştırmasını yapmaktır. Yöntemler: Tiroid sintigrafisi yapılan yaşları 8-85 yaş aralığında değişen 866 (663 kadın, 203 erkek) hastanın görüntüleri retrospektif olarak değerlendirildi. Görüntülerde piramidal lob varlığı ve lokasyonu belirlendi. Hastalar cinsiyet, nodüler/diffüz guatr varlığı, tiroid foksiyon testi sonuçlarına göre ayrı ayrı gruplanarak piramidal lob bulunma oranları ve gruplar arasında anlamlı fark olup olmadığı hesaplandı. Bulgular: Sekiz yüz altmış altı hastanın 156’sının (%18) sintigrafi görüntüsünde piramidal lob izlendi. Piramidal lob izlenen hastaların 126’sı (%81) kadın, 30’u (%19) erkekti. Piramidal lob, 76 (%48) hastada sol lobdan, 61 (%40) hastada sağ lobdan, 19 (%12) hastada isthmustan kaynaklanmaktaydı. Piramidal lob izlenme oranı ötiroidi ve hipertiroidi için %18 iken hipotiroidide %15 olarak saptandı. Piramidal lob görülme sıklığı nodüler guatr hastalarında %13, diffüz guatr hastalarında %43, normal tiroid bezi sintigrafisi izlenenlerde ise %20 olarak bulundu. Yapılan istatistiksel değerlendirmede, diffüz guatr olan hastalarda piramidal lob görülme oranı diğer hastalardan anlamlı derecede yüksek bulundu (p<0,001). Sonuç: Özellikle total tiroidektomi gereken hastalarda operasyon öncesinde piramidal lobun görüntülenmesi, daha sonra ortaya çıkabilecek nüksleri azaltarak hastanın tedavi ve takibini kolaylaştıracaktır.
