脑内海绵状血管瘤(CVM)比较少见,临床表现不典型,手术适应症不好掌握。以桥脑为好发部位的脑干CVM报告很少。本文报告经手术切除和病理确诊的脑干CVM5例,并结合文献19例进行讨论。本文5例为男性4例,女性1例,年龄39—51岁,既往病史中有不同程度的头痛呕吐,面神经麻痹,外展神经麻痹、突发性眩晕、小脑症状、半身感觉和肌力减退等症状。既往检查中CT承脑干出血2例,蛛网膜下出血1例。因上述症状反复发作加重而入院。CT示四脑室底、桥脑被盖部为高密度区。MRI表现为典型的网状核和黑色边缘。血管造影均未见异常。诊断为脑干海绵状血管瘤,行后颅凹开颅血管瘤切除术,术后病理证实。术后恢复尚好出院。本病特 Cerebral cavernous hemangioma (CVM) is rare, clinical manifestations are not typical, and surgical indications are not well understood. Brain stem CVM reports with few pons in the predilection site. This article reports 5 cases of brain stem CVM surgically resected and pathologically diagnosed, and 19 cases of literature are discussed. This article 5 cases of 4 males and 1 female, aged 39-51 years old, with varying degrees of headache vomiting, facial nerve palsy, abducens nerve palsy, sudden vertigo, cerebellar symptoms, half-body sensation and decreased muscle strength in previous medical history. Other symptoms. In the previous examination, CT brain stem bleeding was found in 2 cases and subarachnoid hemorrhage in 1 case. Repeated attacks due to the above symptoms were admitted to hospital. CT showed a high density area at the base of the fourth ventricle and pons. MRI presents a typical reticular nucleus and black margin. No abnormal angiography. The brain stem cavernous hemangioma was diagnosed and the posterior cranial fossa craniotomy was performed. Pathologically confirmed. Postoperative recovery is still good. This disease special
