Many cases of retroperitoneal hematoma related to spine surgery have been reported, however, most of them were caused by major vessel injury related to intradiscal or retroperitoneal procedures. We report an unusual case of a retroperitoneal hematoma followed by surgical excision of the lumbar extradural arachnoid cyst without intradiscal procedure. To our best knowledge, this complication without intradiscal procedure has not been described previoulsly. The pathogenetic mechanism of retroperitoneal hematoma in this report is unclear. We discuss the plausible pathophysiological mechanisms of retroperitoneal hematoma which developed after excision of arachnoid cyst.
Key Words: Retroperitoneal hematoma; Extradural arachnoid cyst; Laminoplasty
