A 79-year-old male presented with recurrent maxillary ameloblastoma with intracranial invasion into the left orbit, previously histologically diagnosed as benign ameloblastoma. Skull x-ray films and computed tomography showed the multicystic mass had destroyed the skull base. The tumor was nearly completely removed. However, microscopic examination revealed residual tumor cells around the left optic nerve. Histological examination found no malignant transformation in the tumor specimen. Aggressive complete removal of maxillary ameloblastoma should be attempted even in cases of intracranial invasion.
一名79岁男性因复发性上颌成釉细胞瘤伴颅内侵犯至左侧眼眶就诊，此前组织学诊断为良性成釉细胞瘤。颅骨X线片和计算机断层扫描显示多囊性肿块已破坏颅底。肿瘤几乎被完全切除。然而，显微镜检查发现左侧视神经周围有残留肿瘤细胞。组织学检查未发现肿瘤标本中有恶性转化。即使在颅内侵犯的情况下，也应尝试积极彻底切除上颌成釉细胞瘤。
