Figure 8 Spontaneous renal hemorrhage. A and B: Sagittal (A) and (B) computed tomography of the right kidney demonstrating a homogenous hypoattenuating mass infiltrating the inferior portion of the right renal parenchyma, consistent with renal lymphoma (white arrow). A few months later, the patient presented with acute abdominal/right flank pain; C and D: Coronal (C) and (D) axial computed tomography demonstrating a hyperdense subcapsular collection consistent with spontaneous renal haemorrhage and subcapsular hematoma (white arrow) with slight extension into the perinephric space (black arrow).
