Demonstration of thyroidal metastasis from lung cancer by F-18 FDG PET scan.

A case is presented of detection of a secondary thyroid cancer arising from a pulmonary adenocarcinoma by fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET). The need to investigate thyroidal hypermetabolic foci detected incidentally on PET scans is well established so as not to miss a primary thyroid cancer. However, as our case illustrates, the possibility of metastatic thyroid cancer, even though less common, should be considered.

Early failure of unicompartmental knee arthroplasty.

We are reporting the relatively poor results obtained in patients receiving a unicompartmental knee arthroplasty (UKA). Thirty-six patients underwent 39 UKAs from December 2002 to June 2004. All received a DePuy Preservation design (DePuy, Warsaw, In) with an all-poly tibial component.
