Leptomeningeal cyst, also known as growing skull fracture in adults, is a very rare complication usually related to childhood head trauma. It is presumed to occur following a skull fracture during childhood associated with a Dural tear and projection of arachnoid membranes, which gradually erodes the fractured bone and grows aided by the normal pulsations of the brain. Here, we present a case of Type 1 leptomeningeal cyst in the left parietal bone in a 22-year-old male adult who presented years after sustaining head injury during his early childhood. Computed tomography scan was crucial in the accurate diagnosis of the case.
柔脑膜囊肿，在成人中也被称为生长性颅骨骨折，是一种非常罕见的并发症，通常与儿童期头部创伤有关。据推测，它是在儿童期颅骨骨折伴有硬脑膜撕裂和蛛网膜下腔膜突出后发生的，蛛网膜下腔膜逐渐侵蚀骨折的骨头，并在大脑正常搏动的辅助下生长。在此，我们报告一例22岁男性成人左顶骨1型柔脑膜囊肿病例，该患者在幼儿期头部受伤多年后出现症状。计算机断层扫描对该病例的准确诊断至关重要。
