A 70-year-old man was admitted with a swelling on the left parietal region, which had grown progressively but slowly for three years. During the last six months the swelling increased in size relatively faster. The lesion was excised totally and sent for pathological examination. The histologic diagnosis was classical meningothelial meningioma. The specimen included some fragments of the skull, however, there was no evidence of an intracranial origin of the tumor. Eighteen months after surgery there was no evidence of recurrence or neurological deficit. Even though primary extracranial meningioma is a rare neoplasm, it should be included in the differential diagnosis of soft tissue tumors above all in the head and neck region.

Rationale: Neuroendocrine tumors (NETs) originate from neuroendocrine cells and they are depicted with both nerve cells as well as hormone-producing cells. These tumors were initially discovered in extracranial locations and central nervous system involvement is often a result of metastasis. Herein, we present a very rare case of primary intracranial neuroendocrine tumor (PINET) that masqueraded as meningioma at the sphenoid ridge with metastasis to the spinal cord in a patient without a known history of extracranial NET at the time of diagnosis.
