چکیده
|
Herein, we report the f-18 fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/computed tomography (ct) findings of a benign solitary fibrous tumor (sft) of the kidney. the patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on ct images. the ct scan showed a lobulated tumor arising from the hilum of the right kidney. the tumor consisted of two components with different patterns of enhancement. most of the tumor demonstrated moderate enhancement from the corticomedullary to nephrographic phase. a small nodular component at the caudal portion of the tumor showed avid enhancement in the corticomedullary phase and rapid washout in the nephrographic phase in contrast-enhanced ct. fdg-pet/ct was performed and showed weak fdg accumulation (suvmax=2.30 and 1.91 in the main and small caudal components). although renal cell carcinoma was preoperatively diagnosed, histopathological examination revealed renal sft, with no malignant potential. therefore, when a renal tumor with contrastmedium enhancement and low fdg accumulation is demonstrated, sft should be considered as a differential diagnosis in addition to renal cell carcinoma.
