A Rare Case of "Periportal Cuffing" as an Incidental Finding on [.sup.18F]-FDG PET/CT/[.sup.18F]-FDG PET/BT'de Insidental Olarak Saptanan Nadir Bir "Periportal Cuffing" Olgusu

A 7-year-old boy with known diagnosis of hereditary spherocytosis and ulcerative colitis was referred for [.sup.18F]-fluorodeoxyglucose ([.sup.18F]-FDG) positron emission tomography/computed tomography after detection of a 28 mm lesion suspicious for malignancy in spleen on upper abdomen magnetic resonance imaging (MRI). As an incidental finding, a moderately increased uptake of [.sup.18F]-FDG was observed in periportal region with no definable mass. MRI revealed compatible findings with "periportal cuffing" as described on ultrasonography. Keywords: Periportal cuffing, fluorodeoxyglucose, positron emission tomography, magnetic resonance imaging Bilinen herediter sferositoz ve ulseratif kolit tanisi olan 7 yasinda erkek hastaya dalakta 28 mm boyutlu malignite supheli lezyon gorulmesi sebebiyle [.sup.18F]-florodeoksiglukoz ([.sup.18F]-FDG) pozitron emisyon tomografisi/bilgisayarli tomografi uygulanmistir. Insidental bir bulgu olarak periportal bolgede karsiliginda tanimlanabilen bir lezyon olmayan artmis [.sup.18F]-FDG tutulumu izlenmistir.
