Extracranial Extension of Intracranial Atypical Meningioma En Plaque with Osteoblastic Change of the Skull
نویسندگان
چکیده
Meningioma is a common primary tumor of central nervous system. However, extracranial extension of the intracranial meningioma is unusual, and mostly accompanied the osteolytic change of the skull. We herein describe an atypical meningioma having extracranial extension with hyperostotic change of the skull. The patient was a 72-year-old woman who presented a large mass in the right frontal scalp and left hemiparesis. Brain magnetic resonance imaging and computed tomography scans revealed an intracranial mass, diffuse meningeal thickening, hyperostotic change of the skull with focal extension into the right frontal scalp. She underwent total removal of extracranial tumor, bifrontal craniectomy, and partial removal of intracranial tumor followed by cranioplasty. Tumor pathology was confirmed as atypical meningioma, and she received adjuvant radiotherapy. In this report, we present and discuss a meningioma en plaque of atypical histopathology having an extracranial extension with diffuse intracranial growth and hyperostotic change of the skull.

PET/CT detection of multiple extracranial localizations in a patient with anaplastic meningioma
We report herein a case of a 65-year-old male with intracranial recurrence of atypical meningioma initially treated with a combination of surgical resection and gamma knife radiotherapy. Afterwards, he underwent a Ga-DOTANOC PET/CT scan in order to evaluate the feasibility of peptide receptor radionuclide therapy (PRRT). The scan identified multiple pulmonary, pleural and lymph node localizatio...
متن کاملAn En Plaque Meningioma of the Temporal Bone, Complicating with a Cholesteatoma, Chronic Otitis Media and an Intracranial Abscess
We describe an initially misdiagnosed case of a meningioma en plaque of the temporal bone. The tumor had obliterated the external ear canal, induced a chronic inflammation and a cholesteatoma of the external and middle ear, and complicated with an external fistula and intracranial abscess formation. Massive bone involvement and scarce soft tissue component of the skull base meningioma en plaque...

The magnetic resonance (MR) appearance of intracranial meningioma typically is of an extraaxial mass that enhances intensely after contrast injection (1–3). However, difficulty in differentiating a meningioma from other processes can occur because of the tumor’s location or other features (1–5). En plaque meningioma can be difficult to image and can simulate other lesions, especially when near ...
متن کاملExtracranial Intraluminal Extension of Atypical Meningioma within the Internal Jugular Vein
Meningiomas represent the most common benign intracranial neoplasms, and may spread by direct extension into nearby venous sinuses, but gross spread to the extracranial venous system is uncommon. We report the case of a patient with extracranial intraluminal spread of meningioma within the internal jugular vein to level III of the neck. Review of the preoperative assessment and management is al...

Extracranial extraspinal meningiomas (less than 1% of all meningiomas) frequently occur in the head and neck. The radiographic findings of extracranial meningioma of the head and neck are not pathognomonic. However, the location of the tumor in the pathway of cranial nerves or adjacent to the skull base, the demonstration of a well circumscribed, solid, enhancing mass by computed tomography, an...
