目的:探讨少见慢性期脑出血CT表现特点,提高对本病的认识,减少误诊。方法:回顾性分析12例经手术和螺旋CT随访证实的少见慢性期脑出血病例的CT表现。结果:12例中首次CT平扫4例病灶为稍高密度影,8例为等、低密度影。增强扫描8例病灶呈环形、脑回状强化,周围见低密度水肿带。本组误诊为脑肿瘤8例,脑脓肿2例,脑梗死2例。结论:少见慢性期脑出血首次CT检查往往误诊,CT增强扫描及随访复查对鉴别诊断有意义。
Objective: To investigate the CT features of rare chronic cerebral hemorrhage and to improve the understanding of the disease and reduce the misdiagnosis. Methods: The CT findings of 12 cases of chronic intracerebral hemorrhage confirmed by surgery and spiral CT follow-up were retrospectively analyzed. Results: In the 12 cases, the first CT scan showed a slightly higher density of lesions in 4 cases, and the lower one was in 8 cases. Enhancement of the lesion in 8 cases was ring-shaped, enhanced back to the brain, surrounded by low-density edema zone. This group misdiagnosed as brain tumor in 8 cases, 2 cases of brain abscess, 2 cases of cerebral infarction. Conclusion: The first CT examination of rare chronic intracerebral hemorrhage is often misdiagnosed, CT enhanced scan and follow-up review of differential diagnosis is meaningful.
