[18F-FDG PET/CT diagnosis of liver cyst infection in a patient with autosomal dominant polycystic kidney disease and fever of unknown origin].

The diagnosis, localization and treatment of infected cysts in the kidney or liver of patients with autosomal dominant polycystic kidney disease (ADPKD) remain a clinical challenge. We report the findings of (18)F-FDG PET-CT in an ADPKD diagnosed patient who required renal transplantation five years before and in his follow up presented repeated episodes of bacteriemia without known focus on radiological tests performed. The (18)F-FDG PET-CT scan showed numerous hypermetabolic images with focal or ring-shaped morphology related to the content and the wall of some hepatic cysts.

[Papillary thyroid carcinoma synchronous with breast cancer: an incidental finding in an (18)F-FDG PET-CT study carried out in a search for occult breast cancer].

The most common cause of metastatic involvement of axillary lymph nodes in women is ipsilateral breast cancer. The definition of occult breast malignancy has changed over time. Nowadays, it is considered to exist when it coincides with an isolated metastatic axillary abnormal lymph node in the absence of a palpable tumor in the ipsilateral breast, non-diagnostic breast tumor mammography and no detection of other malignancies outside the breast which could potentially affect the axillary nodes.
