A Single Hepatic Metastasis of Cranial Meningioma on [¹⁸F]FDG PET/CT 16 Years After Initial Surgery

Abstract

Hepatic metastases of cranial meningiomas are rare, particularly when they present as a delayed, solitary metastasis, which poses a challenge for imaging-based diagnosis. [¹⁸F]FDG PET/CT facilitates diagnosis and posttreatment restaging, whereas somatostatin receptor–targeted PET demonstrates high sensitivity and specificity in the diagnosis of meningiomas and may potentially evaluate the viability of theranostics approaches, particularly for treatment-resistant meningiomas.
