Abstract

Hemangiomas are benign mesenchymal neoplasms that rarely occur in the kidney and perirenal space. Perirenal hemangiomas can mimic the appearance of exophytic renal cell carcinoma or various retroperitoneal tumors. We report a case of perirenal hemangioma detected by dynamic enhanced computed tomography in a 43-year-old female.

Keywords: Hemangioma, Retroperitoneal Space, Tomography, Spiral Computed

A. Contrast-enhanced arterial phase CT showing a small, peripheral-enhancing mass (arrow) in the right perirenal space. There is a mild thickening of the anterior perirenal fascia (small arrow) adjacent to the mass.
B, C. Contrast-enhanced CT images of the venous phase (B) and delayed phase (C) revealing homogeneous enhancement of the perirenal mass (arrows). The mass does not adhere to the surface of the right kidney. It is accompanied by mild fat stranding.
D. Photomicrograph of the perirenal mass showing the proliferation of small capillary vessels (hematoxylin and eosin staining, × 20). The mass is surrounded by perirenal fat tissue.
E. Coronal reformatted image of enhanced arterial phase CT revealing a small mass (arrow) with peripheral globular enhancement (short arrow), similar to that seen in hepatic hemangioma, around the right kidney.
