Benign extracranial meningioma with pulmonary metastasis: a case report and review of literature

Abstract

Abstract Background Meningiomas are common central nervous system tumors, predominantly intracranial, they rarely develop extracranially. Moreover, benign meningiomas seldom metastasize. Case presentation This article presents a case report of a 55-year-old Chinese male patient with a primary World Health Organization grade 1 meningioma originating from the petrous apex of the temporal bone, accompanied by pulmonary metastasis. Following two incomplete resections of the primary tumor, the patient underwent radiotherapy and has since maintained a stable condition. Conclusion The case report highlights the rare occurrence of pulmonary metastasis in a benign World Health Organization grade 1 meningioma originating from an extracranial site. It also illustrates the important role of radiotherapy in treating patients with meningioma. Additionally, a review of related literature is provided to gain insights for the diagnosis and treatment of the disease.
