İntraabominal Kistik Lezyonların Tanısında Doku Harmonik Ultrasonografi ve Bilgisayarlı Tomografinin Rolü

Abstract

Amaç: Batın Ultrasonografi (US) ve Bilgisayarlı Tomografi (BT) tetkikleri Radyoloji Kliniklerinde sıklıkla kullanılan görüntüleme yöntemleridir. Bu incelemeler sırasında batında sıklıkla kistik lezyonlar tespit edilmektedir. Bu kistlerin klinik önemini belirlemek ve karakterize etmek önemli bir sorundur.

Yöntem: İstanbul Eğitim ve Araştırma Hastanesi Radyoloji Kliniği US ve BT ünitelerinde abdominal görüntüleme yapılan ve kistik lezyon saptanan 145 hastanın bulguları retrospektif olarak incelendi. Abdominal organlarda veya batın boşluğunda saptanan, organlar ile ilişkisi olmayan kistik lezyonların BT bulguları gözden geçirildi ve ayrıca yeni US görüntü elde yöntemi olan Doku Harmonik Görütüleme (THI) 'nin kistik lezyonların karakterizasyonuna katkısı incelenmiştir.

Bulgular: Batında kistik lezyon tespit edilen 56 erkek (%39,3) ve 89 kadın (%60,7) olmak üzere toplam 145 hasta dahil edildi. En sık böbreklerde (n:68, %46,89) ve ikinci sıklıkta karaciğerde (n:65; %44,82) kistik lezyonlar saptadık. Ayrıca 5 olguda (%3.44) dalakta, 7 olguda (%4,82) pankreasta, 5 olguda (%3,44) karın boşluğunda kistik lezyon tespit ettik. Tüm olgularımızda hem THI görüntülemede hem de BT incelemesinde kistik lezyonlar görüntülenebildi.

Sonuç: THI inceleme özellikle kistin duvarı özelliği, internal septa ve kist içi solid komponent varlığını göstermede, BT inceleme ise özellikle duvar kalsifikasyonu ve apsede hava varlığının yanı sıra intramural solid komponenti göstererek kistik lezyonları karakterize etmede değerli bilgiler sağlar.

The Role of Tissue Harmonic Ultrasonography and Computerized Tomography in the Diagnosis of Intraabdominal Cystic Lesions

Abstract

Aim: Abdominal Ultrasonography (US) and Computed Tomography (CT) examinations are imaging methods frequently used in Radiology Clinics. During these examinations, cystic lesions are frequently detected in the abdomen. It is an important problem to identify and characterize the clinical significance of these cysts.
Methods: The findings of 145 patients who underwent abdominal imaging in the US and CT units of the Istanbul Training and Research Hospital Radiology Clinic and were found to have cystic lesions were analyzed retrospectively. The CT findings of cystic lesions detected in the abdominal organs or the abdominal cavity were reviewed, and the contribution of the new US image acquisition method, Tissue Harmonic Imaging (THI), to the characterization of cysts was examined.
Results: A total of 145 patients, 56 men (39.3%) and 89 women (60.7%) with cystic lesions in the abdomen, were included. We detected cystic lesions most frequently in the kidneys (n:68, 46.89%) and second most frequently in the liver (n:65; 44.82%). In addition, we detected cystic lesions in the spleen in 5 cases (3.44%), in the pancreas in 7 cases (4.82%), and in the abdominal cavity in 5 cases (3.44%). In all our cases, cystic lesions could be visualized in both THI imaging and CT examination.
Conclusion: THI examination provides valuable information in characterizing cystic lesions, especially by showing the wall feature of the cyst, the internal septa and the presence of intra-cystic solid component, while CT examination especially shows the wall calcification and the presence of air in the abscess, as well as the intramural solid component.
