Question: What is the eponymous name for this appearance of the kidney and the associated syndrome? Hint: these patients may present with dramatic systemic hypertension, most commonly following trauma or surgery.

Answer: This is a Page kidney, or Page phenomenon, where the kidney’s parenchyma is compressed due to a subcapsular hematoma or urinoma (commonly after trauma or surgical/procedural intervention). This leads to hyperreninemic hypertension. The treatment is surgical evacuation, or in extreme cases, nephrectomy.
