In recent years, 68Ga-FAP inhibitor has emerged as a possible substitute radiotracer to FDG for imaging of most of the tumors. Here, we report a 7-year-old girl diagnosed with recurrent papillary tumor of the pineal gland, presenting with complaints of headache and vomiting. 18F-FDG PET/CT revealed an FDG-avid enhancing lesion in the posterior part of the third ventricle.

Aging-induced hepatic dysfunction can impair cholesterol metabolism, reducing the availability of cholic acid (CA, bile-acid) in brain. CA is reported to have neuroprotective characteristics in preclinical investigations of Alzheimer's disease (AD). Our aim is to probe the causal-connectivity between the players: amyloid, cholic acid and cerebral-blood-flow, and thereby explore therapeutic applicability in AD.

Methods: This retrospective study was conducted in a tertiary care center, which included 20 patients who failed atlanto-axial surgery from January 2013 to June December 2021. They were evaluated using X-ray, computed tomography, and magnetic resonance imaging examinations, and their clinical data were accessed from the hospital's medical records department and the picture archiving and communication system.
