Spontaneous Rupture of Renal Cell Carcinoma in a Horseshoe Kidney: A Case Report


Figure 1.
Figure 1. Enhanced computed tomography in the first examination showed left retroperitoneal hematoma (A) and a horseshoe kidney and a hypervascular solid mass (B). The white arrows indicate extravasation of contrast agent (A) and a renal tumor (B).
Figure 2.
Figure 2. Digital subtraction angiography with selective catheterization of renal arteries shows active bleeding from a branch from renal arteries (A). The white circle in a broken line indicates an avascular area and pooling of contrast agent. Aortography after TAE showed disappearance of extravasation of contrast agent (B). The white arrow indicates the embolized portion.
Figure 3.
Figure 3. The gross appearance of the removed kidney revealed a white and yellow solid tumor of 6 cm in diameter located at the lower pole.
