Simultaneous occurrence of histologically different primary brain tumours is rare, and its preoperative diagnosis is still challenging. The explanations for the simultaneous occurrence of different primary intracranial tumours in the absence of phacomatoses or prior radiation exposure are at present hypothetical, and these tumours could be simply coincidental. Herein, we report a case of a boy presenting with features of raised intracranial pressure and right-sided sensorineural hearing loss. Brain MRI revealed two different neoplastic pathologies at different sites: an intrasellar and suprasellar craniopharyngioma and a right cerebello-pontine angle epidermoid. To the best of our knowledge, this is the first report in literature of a craniopharyngioma coexisting with an epidermoid, in the same individual.
组织学上不同的原发性脑肿瘤同时出现的情况很少见，其术前诊断仍然具有挑战性。在没有错构瘤或既往放疗史的情况下，不同原发性颅内肿瘤同时出现的原因目前只是推测，这些肿瘤可能仅仅是巧合。在此，我们报告一例男孩，表现为颅内压升高和右侧感音神经性听力丧失。脑部磁共振成像（MRI）显示在不同部位有两种不同的肿瘤病变：鞍内和鞍上颅咽管瘤以及右侧桥小脑角表皮样囊肿。据我们所知，这是文献中首例同一患者中颅咽管瘤与表皮样囊肿共存的报告。
