F-18 Fdg PET/CT Findings of a Patient with Takayasu Arteritis Before and After Therapy.

Unlabelled: Vasculitis is defined as inflammation and necrosis with leukocytic infiltration of the blood vessel wall. Takayasu arteritis is a chronic inflammatory arteritis that primarily involves the aorta and its main branches. A 64-year-old female patient with a 2-month history of fever of unknown origin was presented to our clinic for F-18 FDG PET/CT imaging.

Bilateral breast involvement of Hodgkin lymphoma revealed by FDG PET/CT.

The involvement of breast tissue with Hodgkin's lymphoma (HL) has been reported in very few cases up to date. We report a 33-year-old woman who had been treated and followed up with nodular sclerosing HL for 7 years, and admitted with recurrent disease. The fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) images revealed disseminated disease with the involvement of bilateral breast tissues showing FDG uptake.

The value of FDG PET/CT in the initial staging and bone marrow involvement of patients with multiple myeloma.

Objective: The aim of this study was to describe the role of positron emission tomography/computed tomography (PET/CT) with fluorine-18 fluorodeoxyglucose (FDG) in the detection of skeletal and visceral involvement in patients with MM (multiple myeloma) at the initial diagnosis and to evaluate the relation between maximum standardized uptake values (SUVmax) of FDG with bone marrow cellularity and plasma cell ratios.

Materials And Methods: The study population consisted of 42 patients (15 F, 28 M; mean ± SD age; 47 ± 12 years). Thirty-two patients were referred for initial diagnosis and ten patients were referred for assessment of therapy response.
