A Rare Case of "Periportal Cuffing" as an Incidental Finding on 18F-FDG PET/CT.

ABSTRACT

A 7-year-old boy with known diagnosis of hereditary spherocytosis and ulcerative colitis was referred for 18F-fluorodeoxyglucose (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 18F-FDG was observed in periportal region with no definable mass. MRI revealed compatible findings with "periportal cuffing" as described on ultrasonography.
