Recurrent Primary Extracranial Meningioma: A Case Report and Literature Review of a Rare Scalp Tumor

Year: 2026

Type: article

Abstract: Extracranial meningiomas are rare tumors that arise outside the cranial cavity and can clinically mimic benign soft tissue lesions. Due to their slow growth and nonspecific appearance, they are often misdiagnosed. Complete surgical excision remains the mainstay of treatment. A 35-year-old female presented with a three-year history of a painless, slowly growing left frontal scalp swelling. On examination, the lesion measured approximately 3-4 cm in diameter, was firm, had normal overlying skin, was very sensitive to touch, and showed no neurological deficits. Surgical excision was performed under general anesthesia. A well-defined lesion was identified and completely excised. At follow-up, the patient developed a recurrent small tumor after seven months and was closely observed. Primary extracranial meningiomas (PEMs) are rare tumors that may involve the scalp. The origin and pathogenesis of PEMs remain theoretical; awareness of their imaging and pathological characteristics is essential for accurate diagnosis. Surgical excision is the primary treatment modality, with outcomes depending on tumor characteristics and completeness of resection.
