18F-Choline PET Detected the Third Ventricle Craniopharyngioma.
Craniopharyngiomas are rare tumors of low histological malignancy (World Health Organization grade I) in the sellar and suprasellar region of the brain. We report a case of the third ventricular craniopharyngioma detected using 18F-choline PET/CT in a 43-year-old man. MRI of the brain revealed an intense gadolinium enhancement focus in the same area. Histology revealed characteristics of papillary craniopharyngioma. Our findings suggest that craniopharyngioma should be included in the differential diagnosis of 18F-choline-avid brain lesions.

Pituitary Non-Functioning Adenoma Disclosed at 18F-Choline PET/CT to Investigate a Prostate Cancer Relapse.
We report the incidental finding of a pituitary macroadenoma on an F-choline PET/CT in a patient with recurrent prostate cancer. The pituitary gland was clearly enlarged and intensely FDG avid (SUVmax, 6.6). The diagnosis was confirmed by a subsequent contrast-enhanced MR evaluation, and the macroadenoma was classified as nonfunctioning on the basis of normality of the specific serum hormonal profile. A follow-up F-choline PET/CT scan performed after 6 months revealed stable dimension, and uptake of the pituitary macroadenoma patient deceased 1 month later. At autopsy, intracytoplasmic vesicles containing growth and prolactin hormones were observed at immunohistochemistry.
