Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm. SFT derived from the renal pelvis is an exceedingly rare entity. In this study, we report a case of renal pelvis SFT and review the relevant literature on this rare tumor.
A 76-year-old man was hospitalized due to right lumbar and abdominal pain. Abdominal computed tomography showed a hypervascular space-occupying renal lesion, sized 2.3 cm × 1.8 cm. Based on the computed tomography findings, the patient was diagnosed with right renal pelvis tumor and underwent neph
We report a rare case of SFT derived from the renal pelvis and discuss the imaging and histopathological features that distinguish renal pelvis SFT from other renal pelvis tumors.
Core Tip: Extrapleural solitary fibrous tumor is an extremely rare mesenchymal neoplasm, especially in cases of origination from the renal pelvis. We report a rare case of renal pelvis solitary fibrous tumor and discuss the detailed radiologic and pathologic findings. The differential diagnosis of renal pelvis solitary fibrous tumor is discussed based on literature review.
