摘　　要：目的分析34例脑脓肿患者脑部经CT增强扫描呈单发环状强化的病灶,并探讨其价值。方法对34例经手术及抗炎治疗证实的脑部病灶进行回顾性分析,讨论脑脓肿呈特异性的单发环状强化诊断及鉴别诊断。结果34例环形强化病灶中:其内低密度18例,等密度7例,混杂密度5例、且有钙化者4例;壁呈均匀强化者24例,壁有结节状强化6例,不规则强化4例;额叶12例,颞叶7例,顶叶6例,小脑半球3例,枕叶2例,脑深部3例;桥脑1例。脑脓肿22例、转移瘤8例、星形细胞瘤2例、陈旧血肿2例。结论CT对脑部单发呈环状强化的脑脓肿诊断及鉴别诊断具有较高价值。Objective The goal analyzes 34 cases with brains assume the single shot ring-like strengthening after the CT enhancement the focus of infection, discusses CT to assume the ring-like strengthened focus of infection to the brain abscess single shot the value. Methods The method carries on the review analysis to 34 cases after the surgery and the anti-inflammation treatment confirmation brain focus of infection, the discussion brain abscess assumes the specificity single shot ring-like strengthening to diagnose and distinguish the diagnosis. Results 34 cases ring-like strengthening focus of infection ： Among them the low density were 18 cases, the equilibrium density 7 cases, the promiscuous density 5 examples, also have the calcification 4 examples ; The wall assumes the even strengthening 24 examples, the wall has the knot nodular to strengthen 6 examples, strengthens 4 cases not regularly ; Temporal lobe 12 examples, nie leaf 7 cases, parietal lobe 6 cases, cerebellar hemisphere 3 cases, occipital lobe 2 examples, brain depth portion 3 examples ; Pons 1 example. Brain abscess 22 examples, shift lump 8 cases, star type cytoma 2 cases, obsolete haematoma 2 cases. Conclusion CT assumes ring-like strengthened to the brain single shot the brain abscess diagnosis and the distinction diagnosis has the high value.
