68 Ga-DOTATATE and 18 F-FDG PET Imaging of a Rare Chordoid Meningioma With Intracranial Recurrence and Extracranial Metastases

Clin Nucl Med. 2024 Jul 1;49(7):e354-e356. doi: 10.1097/RLU.0000000000005237. Epub 2024 Apr 5.

Abstract

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.
