ABSTRACT
BACKGROUND:
Extracranial metastasis, mainly a feature of World Health Organization (WHO) grade III meningiomas, is only rarely reported in grade II meningiomas. CASE DESCRIPTION We 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.CONCLUSIONS:
This 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.Palavras-chave
