Autoimmune cerebellar hypermetabolism: Report of three cases and literature overview.

We report three cases of vermian cerebellar hypermetabolism in patients with autoimmune encephalitis. One of our patients was positive for anti-Ma2 antibodies and one for anti-Zic4 antibodies while the remaining patient did not present any known antibodies. The seronegative patient deteriorated after immune checkpoint inhibitor treatment for a pulmonary adenocarcinoma and improved with immunosuppressive drugs, which is in favour of an underlying autoimmune mechanism.

Diagnostic value of combining ¹¹C-choline and ¹⁸F-FDG PET/CT in hepatocellular carcinoma.

Purpose: In this prospective study, our goal was to emphasize the diagnostic value of combining (11)C-choline and (18)F-FDG PET/CT for hepatocellular carcinoma (HCC) in patients with chronic liver disease.

Methods: Thirty-three consecutive patients were enrolled. All patients were suspected to have HCC based on CT and/or MRI imaging.

(18)F-FDG PET/CT in tuberculosis: an early non-invasive marker of therapeutic response.

Objective: To evaluate the potential of (18)F-fluoro-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for early therapeutic intervention in patients with probable or confirmed tuberculosis (TB).

Methods: Twenty-one consecutive human immunodeficiency virus negative patients were prospectively included. All patients underwent (18)F-FDG PET/CT before and after 1 month of anti-tuberculosis treatment.
