Two patients with non-traumatic acute subdural haematoma were observed, initially without surgical intervention. Eleven days after the onset, each patient developed hemiparesis and an increase in severity of headache. Serial computed tomography scans demonstrated that the initial hyperdense haematomas became hypodense with a definite increase in volume. The term "symptomatic subacute subdural haematoma" was proposed to properly define this pathological process, which necessitated removal of the haematoma in the subacute stage. The mechanism of increase in the volume of the haematoma is discussed.
观察了两名非创伤性急性硬膜下血肿患者，最初未进行手术干预。发病11天后，每名患者均出现偏瘫，头痛加重。系列计算机断层扫描显示，最初的高密度血肿变为低密度，体积明显增加。提出了“有症状亚急性硬膜下血肿”这一术语，以恰当定义这一病理过程，该过程需要在亚急性期清除血肿。文中讨论了血肿体积增加的机制。
