    Journal: Brain Tumor Pathol; 2008; 25(2):91-5. PubMed ID: 18987835.
    Abstract:
    We report a rare case of chordoid meningioma arising in the pineal region, which presented in a 22-year-old woman. Her only complaint was headache, and neurological examination revealed no deficits. She had suffered from prolonged fever a few weeks earlier, and her hematological findings included hypochromic microcytic anemia and a high serum level of C-reactive protein (CRP). Cranial magnetic resonance (MR) images demonstrated a 25 x 30 mm mass in the pineal region, which showed iso-to low intensity on T1-weighted images (T1WI), high to low intensity on T2-weighted images (T2WI), and homogeneous enhancement with gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA). We performed subtotal removal of the tumor with an occipital transtentorial approach (OTA), and all her preoperative symptoms completely abated. Histological examination of this tumor specimen showed the typical pattern of chordoid meningioma. Chordoid meningioma has been known to correspond with Castleman's disease, and pineal meningiomas are extremely rare among intracranial meningiomas. The details of this case are presented with a review of the literature.
