目的 :探讨胼胝体出血的临床表现、病因及影像学特点。方法 :回顾性分析了 5例经头颅CT及MRI扫描证实的胼胝体出血的临床及影像学资料。结果 :胼胝体出血占同期脑出血住院病人的 1 2 % ,病因多为动脉瘤或血管畸形。结论 :胼胝体出血极易破入蛛网膜下腔和脑室 ,临床上若诊断为蛛网膜下腔出血的患者 ,应尽可能行头颅CT及MRI检查 ,并尽可能行脑血管造影检查 ,以明确病因 ,对症治疗。
Objective: To investigate the clinical manifestations, etiology and imaging features of corpus callosum hemorrhage. Methods: Clinical and imaging data of 5 cases of corpus callosum hemorrhage confirmed by skull CT scan and MRI scan were retrospectively analyzed. Results: The corpus callosum hemorrhage accounted for 12% of hospitalized patients with cerebral hemorrhage during the same period. The causes were mostly aneurysms or vascular malformations. Conclusion: The corpus callosum hemorrhage easily ruptured into the subarachnoid space and ventricle. If the diagnosis of patients with subarachnoid hemorrhage in clinical practice, CT and MRI should be performed as far as possible and cerebral angiography as possible to clear the cause ,Symptomatic treatment.
