Abstract

Solitary fibrous tumors are neoplasms of mesenchymal origin that may occur virtually in any body part, most commonly arising from the pleura. Solitary fibrous tumor of the kidney is exceptionally rare, and limited clinical knowledge regarding its behavior makes prognosis of the neoplasm difficult. We report a case of solitary fibrous tumor of the left kidney and describe its clinical, imaging, and pathological features.

Highlights

Solitary fibrous tumor of the kidney is a rare entity with less than 50 cases described in literature [1,2,3]
We report a case of solitary fibrous tumor of the left kidney exhibiting both benign and malignant characteristics, describe its imaging and pathologic features, and perform a literature review
Solitary fibrous tumor (SFT) of the kidney is a rare neoplasm of mesenchymal origin that has been described in patients ranging from 4 to 85 years of age [4,5]

Summary

Introduction

Solitary fibrous tumor of the kidney is a rare entity with less than 50 cases described in literature [1,2,3]. We report a case of solitary fibrous tumor of the left kidney exhibiting both benign and malignant characteristics, describe its imaging and pathologic features, and perform a literature review. A Doppler ultrasound image of the left kidney demonstrates a heterogeneous, predominantly hyperechoic left renal mass with peripheral color flow (white arrows). Further evaluation with a contrast-enhanced abdominal CT (computed tomography) confirmed mass localization to the upper pole of the left kidney (Figure 2). A coronal contrast-enhanced CT image demonstrates a heterogeneous peripherally enhancing mass in the upper pole of the left kidney (white arrows). Cut section of the resected left kidney shows a rubbery pink surface of the mass in the upper pole (black arrows) with central bands of fibrosis and interspersed necrosis.
