Role of ¹⁸F-fluorodeoxyglucose (FDG) and ¹⁸F-2-fluorodeoxy sorbitol (FDS) in autoimmune hypophysitis: a case report.

ABSTRACT:

Background

Autoimmune hypophysitis is a rare disease characterized by the infiltration of lymphocytic cells into the pituitary gland. ¹⁸F-fluorodeoxyglucose (FDG) and ¹⁸F-2-fluorodeoxy sorbitol (FDS) positron emission tomography (PET) are well-established and emerging techniques, respectively, which may aid in the diagnosis and classification of autoimmune hypophysitis.

Case presentation

Here, we report a 40-year-old female diagnosed with central diabetes insipidus and multiple pituitary hormone deficiencies, and MRI revealed homogeneous signals in the pituitary gland as well as thickened in the pituitary stalk. FDG PET localized the pituitary and pituitary stalk lesions and displayed an SUVmax of 5.5. FDS, a sensitive radiotracer for bacterial infectio
