摘　　要：回顾性分析1例垂体母细胞瘤误诊为颅烟管瘤病例的临床、影像、病理及治疗经过,以提高鞍区病变的鉴别诊断能力。本例患者年龄为2岁,以右侧下肢无力2周,右侧上肢无力3天为主诉入院,无明显诱因出现走路不稳,无哭闹、跌倒,无发热、头痛、呕吐,无抽搐、惊厥。右侧膝、跟腱反射稍减弱,右侧Babinski's征可疑阳性。功能评价提示中枢性尿崩症和垂体前叶功能低下。磁共振表现为鞍内及鞍上囊实性占位,诊断为颅烟管瘤。经手术切除后病理诊断为垂体母细胞瘤。对于年龄较小,鞍内及鞍上占位,疑诊为颅烟管瘤或垂体瘤的患者,应尽早活检或手术以明确诊断。To improve the ability of differential diagnose of sellar region lesions,a case of pituitary blastoma misdiagnosed as craniopharyngioma was retrospectively,from clinical,imaging,pathological and the course of diagnosis and treatment.The patient is two years old,the main complaints were right lower limb weakness for two weeks and right upper limb weakness for three days,there were no obvious causes of walking instability,no crying,no fever,no headache,no vomiting,no convulsions,no convulsions.The right knee and achilles tendon reflexes were slightly weakened,and the right Babinski’s sign was suspiciously positive.Functional evaluation showed central diabetes insipidus and hypofunction of anterior pituitary.MRI showed solid and cystic space-occupying in sellar and suprasellar region,which was diagnosed as craniopharyngioma.The pathological diagnosis was pituitary blastoma after operation.For the younger,sellar and suprasellar space-occupying,suspected of craniopharyngioma or pituitary tumor patients,should be timely biopsy or surgery to make a definite diagnosis.
