Abstract:
Ice-ball fracture is a rare and often overlooked entity that may lead to intraprocedural hemorrhage after percutaneous cryoablation of renal masses. There is scant literature on ice-ball fractures associated with percutaneous renal cryoablation. Immediate recognition of the lightning bolt sign during intraprocedural computed tomography can help identify patients who may have developed this complication.
