Although the possibility of spontaneous regression of intracranial arachnoid cysts (AC) during observational follow-up is widely recognized, the number of reports documenting such clinical course, often associated with the mild head trauma, is rather limited. We present a case of nearly complete resolution of the large middle fossa AC in a 5-year-old boy without any identifiable cause in 2.3 years after the initial diagnosis. It once again justifies observational strategy for AC not accompanying by mass effect and manifesting with minimal symptoms or diagnosed incidentally.
尽管人们广泛认识到颅内蛛网膜囊肿（AC）在观察随访过程中有自发消退的可能性，但记录这种临床病程的报告数量相当有限，这种情况通常与轻度头部外伤有关。我们报告了一例 5 岁男孩的大型中颅窝 AC，在初始诊断后 2.3 年内几乎完全消退，无任何可识别的原因。这再次证明了对于不伴有占位效应、症状轻微或偶然诊断的 AC 采取观察策略是合理的。
