Extracranial meningiomas are rare, accounting for 1-2% of all meningiomas with just published in the form of a case report or series. They are categorized as primary or secondary tumors. In this paper, we present a case of extracranial meningioma in the scalp skin, which is believed in Vietnam's first case.
A 38 years old male with a history of brain epidural hematoma surgery in 1995 presented a subcutaneous protruding mass, which revealed approximately 3-centimeters from an incision scar in the left frontoparietal scalp. The tumor was firm, mobilized with contrast enhancement on magnetic resonance image. The complete surgical excision of the whole mass was performed, and histological examination revealed a WHO grade I meningioma.
Epidemiology, classification, diagnosis, treatment as well as prognosis of extracranial meningioma were discussed. We also hypothesized the emergence of extracranial meningioma after an epidural hematoma surgery.
Extracranial meningioma is quite rare, but it could be presented after a traumatic brain injury. Neurosurgery was the first choice, safe and effective treatment.
颅外脑膜瘤较为罕见，占所有脑膜瘤的1%-2%，目前仅有病例报告或病例系列的形式发表。它们被分为原发性或继发性肿瘤。在本文中，我们报告了一例发生于头皮的颅外脑膜瘤病例，据信这是越南首例此类病例。
一名38岁男性，有1995年脑硬膜外血肿手术史，其左额顶部头皮切口瘢痕处出现一个皮下突出肿块，大小约3厘米。肿瘤质地坚硬，磁共振成像显示有对比增强。对整个肿块进行了完整的手术切除，组织学检查显示为世界卫生组织I级脑膜瘤。
讨论了颅外脑膜瘤的流行病学、分类、诊断、治疗及预后。我们还推测了硬膜外血肿手术后颅外脑膜瘤的发生情况。
颅外脑膜瘤非常罕见，但可在颅脑外伤后出现。神经外科手术是首选的安全有效的治疗方法。
