BackgroundExtracranial metastasis, mainly a feature of World Health Organization (WHO) grade III meningiomas, is only rarely reported in grade II meningiomas.Case DescriptionWe report a case of a 48-year-old man who was initially diagnosed in 2010 with an occipital convexity meningioma based on computed tomography scan/magnetic resonance imaging (MRI) and treated with surgical therapy and gamma knife. The first operation achieved a macroscopically complete resection. The tumor was histologically classified as an atypical meningioma. The patient had a recurrence in 2014 on the left tentorial leaflet as noted on postcontrast MRI. The patient was asymptomatic, without focal neurologic deficits. In 2016, the patient reported new-onset pain in the neck and left upper extremity. MRI indicated complete replacement of the C7 vertebral marrow, with a soft tissue component extending posteriorly into the epidural space that appeared to be flattening the thecal sac but without evidence of abnormal cord signal. Histopathology of resection confirmed atypical meningioma.ConclusionsThis case represents a rare instance of intraosseous spine as the first site of metastasis of WHO grade II atypical meningioma and is the first reported case of extracranial metastasis of a meningioma to the C7 vertebral body.Copyright © 2018.
