【摘要】 颅内碰撞瘤临床少见,术前诊断困难,诊断主要依靠术后病理确诊。本文报道的2例颅内碰撞瘤分别位于小脑和鞍区,分别采用后正中入路和翼点入路行开颅手术治疗。其中小脑碰撞瘤肿瘤完整切除,病理结果为转移瘤与脑膜瘤碰撞,术后14个月随访患者因全身多发转移多脏器衰竭死亡;鞍区碰撞瘤次全切除,病理结果为脑膜瘤与垂体瘤碰撞,术后左眼睑上抬困难,左眼视力下降,术后3个月随访左眼睑上抬困难症状缓解,术后1年随访未见肿瘤复发。更多还原

【Abstract】 Intracranial collision tumors are rare in clinic. Preoperative diagnosis is difficult. Diagnosis is mainly based on postoperative pathological results. Two cases of intracranial collision tumors located in cerebellum and sellar region were treated by posterior median approach and pterional approach respectively. The cerebellar collision tumor was completely resected, and the pathological result was the collision of metastatic tumor and meningioma. The patient died of multiple metastatic multiple organ failure 14 months after operation. The sellar region tumor was subtotal resected. The pathological result was a collision of meningioma and pituitary adenoma. Symptoms of upper eyelid lifting were alleviated, and no recurrence was found after 1 year follow-up.更多还原
