Spontaneous perirenal hemorrhage (SPH), also known as Wünderlich's syndrome, is a rare urological emergency. This article reviews the most common causes of SPH and the role of imaging in establishing the correct diagnosis and in guiding the appropriate therapy. A thorough understanding of underlying etiologies, imaging appearances, optimal imaging techniques, and follow-up protocols are crucial to recognize patients with SPH due to benign disease and avoid unnecessary nephrectomies.

Hemangiomatosis is not rare in the liver parenchyma adjacent to a GCH. The presence and extent of hemangiomatosis must be specifically communicated to referring physicians. Surgical candidates have to be carefully selected to avoid complications, such as excessive blood loss and diminished risk of postoperative liver decompensation from apparent overestimation of functional residual volume due to oversight of involved liver areas by hemangiomatosis.
