Bu görsel aðýrlýklý sunuda, mediastinal lenf bezi çalýþmalarý sýrasýnda, endobronþial ultrasonda anekoik görüntü saptanan dört farklý olguyu sunuyoruz. Herbir anekoik görüntü, lenf bezinde koagülatif nekroz iþareti vermekteydi. Tüm olgularda anekoik görüntüler benzer karakteristik özelliklere sahip olmasýna raðmen, patoloji rapor sonuçlarý farklýdýr. Ýki olguda maliginte pozitif idi, bir olguda tiroidden orijin alan benign tümör ve bir olguda da tüberküloz saptandý. Tüm hastalardan EBUS iþlemi için yazýlý onamlar alýndý. Mediastinal patolojilerin tanýsýnda gerekli genel incelemeleri takiben hastanemiz kurallarýna göre iþlemler yapýldý.

In the present pictorial study, we report on four different cases with Endobronchial Ultrasound anechoic images, taken during a mediastinal lymph node study. Each anechoic image had a nodal coagulative necrosis sign. Although the anechoic images had similar characteristics in all cases, the final pathology report was different, with two cases positive for malignancy, one case showing a benign tumor of thyroid gland origin, and one case with tuberculosis. All patients signed informed consent for investigation with the EBUS technique. The procedure was performed in accordance with the regulations of our hospital, and following the usual technique followed in diagnostic mediastinal pathology studies.
