Abstract：
Leptomeningeal cyst (LMC) is a known complication of pediatric head injury but has not been described following a craniotomy other than for craniosynostosis. We present the case of a 20-month-old boy who underwent craniotomy for a traumatic epidural hematoma. There was an inadvertent tear of the dura which was repaired with a pericranial patch and dural sealant. The patient presented with a progressive surgical site swelling 5 months post-surgery and a CT scan revealed an LMC with elevation of the bone flap. He underwent re-exploration with watertight repair of the dural defect and rigid fixation of the bone flap. This iatrogenic LMC provides an opportunity to compare and confirm the pathogenesis vis a vis the more common spontaneous post-traumatic LMC. Our report highlights the importance of proper dural closure and bone fixation after craniotomy in children whose skulls are still growing.
摘要：
脑膜囊肿（LMC）是小儿颅脑损伤的已知并发症，但除颅骨融合外，在开颅手术后尚未描述。我们介绍了一个20个月大的男孩因外伤性硬膜外血肿接受开颅手术的情况。硬脑膜意外撕裂，并用颅骨修补和硬脑膜密封剂修复。患者在手术后5个月出现进行性手术部位肿胀，CT扫描显示LMC，骨瓣抬高。他接受了硬脑膜缺损的水密修复和骨瓣的刚性固定的重新探索。与更常见的自发性创伤后LMC相比，这种医源性LMC提供了比较和确认发病机理的机会。我们的报告强调了颅骨仍在生长的儿童开颅手术后适当的硬脑膜闭合和骨固定的重要性。
