68Ga-FAPI PET/CT in Assessment of Leptomeningeal Metastases in a Patient With Lung Adenocarcinoma

68Ga-FAPI PET/CT in Assessment of Leptomeningeal Metastases in a Patient With Lung Adenocarcinoma Abstract We presented a case of 64-year-old woman with pathologically diagnosed lung adenocarcinoma. Brain metastases were highly suspected due to the appearance of neurological symptoms. However, no abnormal finding in the brain was observed on 18F-FDG PET/CT. Contrast-enhanced MRI showed the presence of leptomeningeal metastases but with a negative cerebrospinal fluid analysis. For this reason, the patient underwent 68Ga-FAPI PET/CT, later fused with MRI scans that showed intense uptake of 68Ga-FAPI in leptomeningeal regions correspondent to the sites of gadolinium enhancement. This case highlights that 68Ga-FAPI would be promising for the identification of leptomeningeal involvement in patients with malignant disease. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Clinical Nuclear Medicine Wolters Kluwer Health

Abstract

Abstract We presented a case of 64-year-old woman with pathologically diagnosed lung adenocarcinoma. Brain metastases were highly suspected due to the appearance of neurological symptoms. However, no abnormal finding in the brain was observed on 18F-FDG PET/CT. Contrast-enhanced MRI showed the presence of leptomeningeal metastases but with a negative cerebrospinal fluid analysis. For this reason, the patient underwent 68Ga-FAPI PET/CT, later fused with MRI scans that showed intense uptake of 68Ga-FAPI in leptomeningeal regions correspondent to the sites of gadolinium enhancement. This case highlights that 68Ga-FAPI would be promising for the identification of leptomeningeal involvement in patients with malignant disease.
