目的：分析脑肿瘤出血的影像表现，旨在早期诊断和治疗。方法选取经手术病理证实并有完整临床和影像资料的56例病例数不少于50例]患者进行回顾性分析，结合文献重点观察脑肿瘤出血的CT和MRI影像表现特点。结果①56例患者中，32例CT和15例MRI影像表现为血肿与肿瘤组织共存，血肿边缘结节或团块状占位呈等密度或等信号或等低混合密度或混杂信号；5例CT和4例MRI表现为单纯性脑出血，出血灶密度或信号均匀或不均。②随访复查中肿瘤周围水肿持续存在并有增大，占位效应加大。③23例CT增强和15例MRI增强扫描，肿瘤组织表现为结节强化，不规则团状强化或花环状强化。榆随访复查2周以上在MRIT2加权上14例病灶周围含铁血黄素环不完整且厚度不均，5例含铁血黄素环缺失。结论脑肿瘤出血具有CT和MRI特征影像表现，早期增强和短期复查对定性诊断和指导治疗具有诊疗意义。

Objective To analyze the imaging findings of brain tumor hemorrhage for the purpose of early diagnosis and treatment. Methods 56 cases with complete clinical and imaging data confirmed by pathology were retrospectively analyzed. And combined with the literature CT and MRI imaging features of brain tumor hemorrhage were analyzed. Results①32 cases of CT and 15 cases of MRI patients showed hematoma and tumor tissue of hematoma coexist, marginal tubercle or lump occupying isodenseor mixed density signal or low or mixed signal. 5 cases of CT and 4 cases tubercle of MRI showed simple cerebral hemorrhage; hemorrhage with homogeneous or heterogeneous density. ②In the follow-up review, CT and MRI showed the lesions appearing as peripheral edema continued to exist and increase, the space occupying effect increased. ③23 cases of CT and 15 cases of MRI enhanced scan showed nodular enhancement, irregular nodular enhancement or ring enhancement. ④19 patients were followed up for review for more than 2 weeks in MRI T2WI with 14 cases of incomplete and uneven thickness hemosiderosis flavin ring and 5 cases of the flavin ring iron loss. Conclusion Brain tumor hemorrhage had CT and MRI features of imaging findings and early enhancement and short review had Clinical significance in qualitative diagnosis and guiding treatment.
