A 51-year-old female who presented with a chief complaint of dysphagia and was found to have a neck mass abutting the carotid sheath. The patient underwent resection and final pathology results revealed a WHO grade 2 chordoid meningioma.

Lessons: This case report demonstrates an atypical case of an extracranial chordoid meningioma adjacent to the carotid sheath. To the authors' knowledge, this is the first reported case of a chordoid meningioma occurring within the soft tissue of the neck

A 44-year-old woman with chordoid meningioma not associated with CS. The patient presented with epilepsy and right hemiparesis (Todd's palsy) on admission. The radiological findings revealed an extraaxial mass lesion in the premotor cortex. They were compatible with a preoperative diagnosis of meningioma. No physical abnormalities related to CS were detected. A left frontal craniotomy was performed. The tumor surface was gelatinous, and it was totally resected with the attached dura mater (Simpson grade I). The patient had an uneventful recovery, and her seizures subsided. The pathological findings of the specimens revealed nests and cords of spindle and epithelioid cells with abundant myxoid matrix, mimicking the features of chordoma. On the basis of radiological, immunohistochemical, and electron microscopic findings, chordoid meningioma was verified
