摘要

BACKGROUND Grade II and III meningiomas[World Health Organization(WHO)classification]rarely have extracranial metastases via the blood circulation;however,we experienced a case with a metaplastic atypical meningioma and local dedifferentiation that metastasized to the jugular vein,carotid artery and subclavian artery at the cervicothoracic junction.Such cases have seldom been reported before.CASE SUMMARY The patient was a 30-year-old man who developed right neck masses with dysphagia,labored breathing,dizziness,and occasional earaches.Eight months earlier the patient was diagnosed with a right parietal lobe neoplasm and hemorrhage at a local hospital due to the sudden onset of headaches and left limb weakness,and the post-operative pathology was a metaplastic atypical meningioma(WHO grade II)with local de-differentiation(WHO III).Magnetic resonance imaging revealed a calcified mass at the root of the neck on the right and a large cystic mass in the right parapharyngeal space.Head and neck angiography showed that the right common carotid artery was compressed and completely occluded,and the jugular vein was enveloped by the tumor and occluded.A balloon occlusion test showed no perfusion in the right common carotid artery.Tumor resection,carotid artery ligation,and subclavian artery reconstruction were performed.The tumor was a malignant meningioma.Postoperatively,the patient had Horner's syndrome and hoarseness.CONCLUSION This case highlights the importance of the link between a large cervical mass and a primary intracranial tumor.Malignant meningioma should not be considered merely as an intracranial metastasis spread through cerebrospinal fluid,it can also be transferred through the circulation to the parapharyngeal space and the cervical great vessels.
