Abstract
INTRODUCTION AND IMPORTANCE: 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. CASE PRESENTATION: 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. CLINICAL DISCUSSION: 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. CONCLUSION: Extracranial meningioma is quite rare, but it could be presented after a traumatic brain injury. Neurosurgery was the first choice, safe and effective treatment.
