Extracranial meningiomas are uncommon tumors and represent an unusual manifestation of a typically intracranial disease. While most are intracranial, primary extracranial presentations may arise independently or represent extensions of intracranial disease. Radiation exposure is a recognized but uncommon risk factor. We present a case of a 66-year-old male patient who developed a painless, preauricular mass more than a decade after cranial radiotherapy for acromegaly. Imaging revealed a well-circumscribed, enhancing lesion centered in the infratemporal fossa, with bony remodeling but no intracranial extension. Surgical excision was performed using a modified Blair approach, preserving the facial nerve. Histology confirmed a WHO Grade I meningioma. This case highlights the importance of long-term follow-up in irradiated patients and the value of multidisciplinary planning for complex skull base tumors.
颅外脑膜瘤是罕见肿瘤，是典型颅内疾病的一种不寻常表现。虽然大多数脑膜瘤位于颅内，但原发性颅外表现可能独立出现，也可能是颅内疾病的延伸。辐射暴露是一个已被认识但不常见的危险因素。我们报告一例66岁男性患者，该患者在因肢端肥大症接受颅脑放疗十多年后出现了一个无痛的耳前肿块。影像学检查显示颞下窝有一个边界清晰、强化的病变，伴有骨质重塑但无颅内延伸。采用改良的布莱尔入路进行手术切除，保留面神经。组织学检查证实为世界卫生组织一级脑膜瘤。该病例强调了对接受放疗患者进行长期随访的重要性以及对复杂颅底肿瘤进行多学科规划的价值。
