Two child and three elderly patients underwent craniotomy for organized and/or partially calcified chronic subdural hematomas (CSHs). The characteristic feature of magnetic resonance imaging was a heterogeneous web-like structure in the hematoma cavity. Both children had undergone one side subduroperitoneal shunt for bilateral CSHs when infants. As a result, the opposite hematoma cavities persisted and developed into calcified CSHs after a couple of years. All three elderly patients with senile brain atrophy showed various systemic complications such as cerebral infarction, diabetes mellitus, leg ulceration, cirrhosis, and bleeding tendency. Craniotomy for removal of the hematoma and calcification achieved good results in all patients. Subdural space created by shunt, craniotomy, or brain atrophy and persisting for a certain period, and additional various brain damage such as microcirculatory disorder, meningitis, encephalitis, or premature delivery may be important in generating calcified or organized CSH.
两名儿童和三名老年患者因有组织的和/或部分钙化的慢性硬膜下血肿（CSH）接受了开颅手术。磁共振成像的特征性表现是血肿腔内呈异质性网状结构。两名儿童在婴儿期时均因双侧CSH接受过一侧硬膜下腹腔分流术。结果，对侧血肿腔持续存在，并在数年后发展为钙化性CSH。所有三名患有老年性脑萎缩的老年患者均出现了各种全身并发症，如脑梗死、糖尿病、腿部溃疡、肝硬化和出血倾向。所有患者通过开颅手术清除血肿和钙化均取得了良好效果。由分流术、开颅手术或脑萎缩形成并持续一定时间的硬膜下间隙，以及其他各种脑损伤，如微循环障碍、脑膜炎、脑炎或早产，可能在钙化性或有组织的CSH形成中起重要作用。
