Abstract

Meningiomas are one of the major primary CNS tumors. Most meningiomas are benign, but rarely, these metastasize to distant organs, the lungs being the commonest site of metastasis. 18 F-FDG PET/CT has been used to evaluate metastatic pulmonary meningioma. However, 68 Ga-FAPI PET/CT has not yet been evaluated. The present case highlights the 68 Ga-FAPI uptake in metastatic pulmonary meningioma in a postoperated case of left tentorial meningioma presenting with lung masses. Image-guided biopsy from the lung mass was consistent with metastatic meningioma.
