Chordoid meningiomas are a rare but increasingly recognized subtype of meningioma. Although some cases have been associated with systemic symptoms, in many instances the clinical features are indistinguishable from those associated with other subtypes of meningioma. Given the prognostic significance of the diagnosis of chordoid meningioma, careful consideration should be given to the diagnosis during histological assessment. The authors describe a rare case of chordoid meningioma in the cervical spinal region.

Chordoid Meningioma: The Rarest Subtype of Grade II Meningioma.

Pathology and Laboratory Medicine, Palmetto General Hospital, Hialeah, USA.
Chordoid meningioma, a rare WHO grade II tumor, is known for its aggressive behavior and high recurrence rate. We report a case of a 44-year-old woman with progressive left-sided weakness, where imaging revealed a 3.0 cm lesion in the right sphenoidal wing with significant midline shift and edema.

Meningioma is the most common primary intracranial tumor in adults, with up to 10% manifesting as multiple tumors. Data on the genomic and molecular changes in sporadic multiple meningiomas are scarce, leading to ongoing debates regarding their evolutionary processes. A comprehensive genetic analysis of a large number of lesions, including precursor lesions, is necessary to explore these two possible origins: clonal and independent.

Objectives: To study each atypical feature in atypical meningioma versus other grade 2 meningiomas and its possible relation to recurrence.
Methods: This is a retrospective study of patients with WHO grade 2 meningioma operated in our institution between 01/2008 and 12/2020. The rate of recurrence, reoperation and readmission were recorded during the follow-up period.
68 Ga-DOTATATE and 18 F-FDG PET Imaging of a Rare Chordoid Meningioma With Intracranial Recurrence and Extracranial Metastases.
Clin Nucl Med

From the Department of Radiology, Mayo Clinic Arizona.
Chordoid meningiomas, rare meningioma variants, are characterized by their histopathological features and clinical behavior resembling that of other chondroid/myxoid neoplasms. We present a case of pathology-proven chordoid meningioma imaged with both 68 Ga-DOTATATE and 18 F-FDG PET images during a complicated postoperative course with multiple episodes of local recurrence and, ultimately, extracranial metastasis. This case underscores the aggressive behavior of chordoid meningiomas while highlighting how molecular imaging plays an important role in clinical monitoring and guidance of management.

Background: Chordoid glioma is a rare slow-growing tumor of the central nervous system. Available world experience includes no more than 200 cases (lesion of the third ventricle in absolute majority of cases). Recognition and treatment of chordoid glioma are currently difficult problems due to small incidence of this disease.
