Leptomeningeal cyst (a growing fracture of childhood) is well recognized as a rare complication of traumatic skull injuries. The clinical and plain roentgenogram findings have been described previously in the literature. These fractures are commonly associated with encephalomalacic changes of the underlying herniated brain tissue that occurs as part of the pathophysiology of leptomeningeal cyst formation. This is a case report of a leptomeningeal cyst with peripheral enhancement of the herniated issue most likely representing the pia mater, and/or development of a highly vascularized pseudodura. The computed tomography findings pre and postcontrast of a growing fracture of childhood have not been previously reported.
柔脑膜囊肿（儿童生长性骨折）是一种公认的外伤性颅骨损伤罕见并发症。其临床及普通X线平片表现此前已有文献报道。这些骨折常与潜在疝出脑组织的脑软化改变相关，这是柔脑膜囊肿形成病理生理学的一部分。本文报告一例柔脑膜囊肿，其疝出组织周边强化最可能代表软脑膜，和/或高度血管化假硬膜的形成。儿童生长性骨折的计算机断层扫描增强前后表现此前未见报道。
