Granülamatosis Polianjitis tanılı beş olgunun Pozitron Emisyon Tomografisi ile değerlendirilmesi

Abstract

Granülomatöz Polianjitis (GPA) eski adıyla Wegener Granülomatozu, öncelikle üst solunum yolları, akciğer ve böbrekleri tutan, granülomatöz nekrotizan vaskülit ile karakterizedir. Hastalığın 'sınırlı' ve 'yaygın' olmak üzere iki formu vardır. Radyolojik bulguları birkaç milimetreden santimetreye kadar değişen çok sayıda bilateral nodüller veya parankimal infiltrasyonlar, kavitasyonlar veya kavitasyonlarla karakterize nodüller olarak görülür. Bu nodüller bazen boyut ve görünüm açısından malignite ile karışabilir. Bu çalışmada, maligniteyi taklit eden GPA tanısı alan 5 olgunun ilk değerlendirmesinde pozitron emisyon tomografisi / bilgisayarlı tomografinin (PET / BT) rolünü tartışmayı amaçladık.

Positron Emission Tomography in the management of five cases with granulomatosis with polyangiitis

Abstract

Granulomatosis with polyangiitis (GPA) formerly Wegener’s Granulomatosis, is characterized by granulomatosis necrotizing vasculitis that primarily involves upper respiratory tracts, lung and kidney. There are two types of disease, ‘limited’ and ‘generalized’. Radiological findings are seen as multiple bilateral nodules that change from a few millimeters to centimeters in size or parenchymal infiltrations, cavitations or nodules presented with cavitations. These nodules sometimes can be confused with malignancy in terms of the size and appearance. In this study, we discussed the role of positron emission tomography/computerized tomography (PET/CT) in the initial evaluation of patients with the diagnosis of GPA mimicking malignancy.
