迟发性颅内血肿的CT检查

目的:分析迟发性颅内血肿的临床表现、CT复查指征及预后。对象与方法:36例颅脑外伤后临床症状进行性加重的迟发性颅内血肿患者均经CT复查,并与第1次CT检查所见比较。结果:经CT复查发现36例颅内血肿,其中,脑内血肿16例(19个病灶),硬膜下血肿7例(伴蛛网膜下腔出血1例),硬膜外血肿9例,以及混合性血肿4例。结论:当颅脑外伤病人临床症状进行性加重时,择期进行CT复查可以发现第1次CT检查未发现的颅内血肿。

CT examinations of late-Occurred intracranial hematoma

Purpose: To analyze the clinical manifestations, CT reexamined indications, as well as the prognosis of late - occurred intracranial hematoma. Subjects and Methods: 36 patients with late - occurred intracra-nial hematoma which were found during clinical manifestations continusly progressing after skull trauma underwent CT reexamination and then the discovered lesions were compared with that be found during first CT examination after skull trauma. Results: 36 patients with late - occurred intracranial hematoma were found through CT reexamination, which included 16 cases (19 lesions) of intracerebral hematoma, 7 cases of subdu-ral hematoma(1 case complicated with hemorrhage of subarachnoid cavities), 9 cases of epidural hematoma, and 4 cases of mixed hematoma. Conclusion: When the severity of clinical symptoms in patients with skull trauma are increasing progressively, performing in good time CT reexamination can discover some new intracranial lesions like as hematoma those were undiscovered during first CT examination.
