Case ReportsFDG PET/CT appearance of multicentric Castleman's disease mimicking lymphoma.
We report a case of a multicentric form of Castleman's disease with multiple lymph nodes showing intense FDG uptake on whole body scan mimicking non-Hodgkin's lymphoma. In this report, the patient had multiple cervical, mediastinal, hilar, retroperitoneal and abnormal lymph nodes in the groin. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography was performed before tissue sampling. (18)F-FDG/PET demonstrated multiple areas of increased uptake in cervical, mediastinal, hilar, retroperitoneal and groin lymph nodes, suggesting a generalized disease of the lymphatic system including non-Hodgkin's lymphoma. ⋯ The histological diagnosis was multicentric plasma cell variant of Castleman's disease. (18)F fluorodeoxyglucose positron emission tomography/computed tomography scan helped to identify the lymph nodes involved throughout the whole body, but did not help to differentiate non-Hodgkin's lymphoma. The clinical conclusions and PET/CT findings are described in this report.

Clinical TrialSentinel lymph node biopsy in patients with operable breast cancer treated with neoadjuvant chemotherapy.
To evaluate the accuracy of sentinel lymph node biopsy (SLNB) in operable breast cancer patients treated with neoadjuvant chemotherapy (NAC). ⋯ SLN biopsy after NAC can predict the axillary status with a high accuracy in patients with breast cancer, avoiding unnecessary ALND.

Is a selective brain (18)F-FDG PET/CT study profitable in patients with small cell lung cancer?
To evaluate the diagnostic yield of a selective brain (18)F-FDG PET/CT in neurologically asymptomatic patients with small cell lung cancer. ⋯ Hypometabolic areas in the cerebral parenchyma are frequently associated to metastatic lesions in patients with small cell lung cancer. The selective brain PET/CT in these patients allows correct staging and early treatment of unsuspected metastasis.
