Abdominal pain and hypotension in a 62-year–old woman 24 h after laparoscopic enucleation of an early-stage RCC. Unenhanced CT acquisition (a) showed renal displacement by hyperattenuating medial peri-renal and posterior para-renal haematoma (*). Post-contrast corticomedullary-phase images (b) depicted foci of active extravasation (thin arrows) near the site of resection (arrow) at the resected inferior renal pole. The haematoma (*) become progressively liquefied and demarcated during CT follow-up (c) and eventually resolved 1 year later (d). (Partially reprinted with permission from Tonolini et al. [52])
