No full textThe diagnostic strategy in patients with fever or inflammation of unknown origin remains a major clinical challenge. The aim of this study was to evaluate the role of F-18-FDG-PET/CT in patients with unexplained elevated C-reactive protein with or without fever. Contribution of F-18-FDG-PET/CT to the final diagnosis was evaluated. In addition we determined whether a differentiation between patients with or without fever is clinically reasonable. Patients, methods: We retrospectively analysed 72 consecutive patients with unexplained elevated C-reactive protein levels (above 8mg/l) that underwent F-18-FDG-PET/ CT in our facility between 10/2009 and 11/2012. 18F-FDG-PET/CT was considered a so-called diagnostic scan when results decisively led to a final diagnosis and adequate therapy with a response of symptoms was initiated due to the PET/CT result. Results: In 60/72 patients (83%) a final diagnosis was established. Diagnoses included infections (58%), non-infectious inflammatory diseases (29%) and malignancies (8%). F-18-FDG-PET/CT was true positive in 47 cases (65%) and the diagnostic scan in 29 patients (40%). Sensitivity of 18F-FDG-PET/CT was 81% and specificity was 86%. Diagnostics, final diagnoses, F-18-FDG-PET/CT results, SUVmax, C-reactive protein levels and the diagnostic scan did not differ significantly between patients with fever and patients without fever. Conclusion: F-18-FDG-PET/CT is a useful method in the diagnostic workup of patients with inflammation of unknown origin. In our series there was no significant difference between patients with or without fever. Regarding F-18-FDG-PET/CTimaging inflammation of unknown origin and unexplained fever can be joined to one entity
Patients with autoimmune thyroiditis Prevalence of benign lymphadenopathy
No full textThe prevalence of cervical lymphadenopathy in autoimmune thyroiditis (AIT) patients is actually unknown. The aim of the study was the detailed retrospective evaluation of 6 index-patients with lymphadenopathy in Robbins level VI and a prospective study with high resolution ultrasound of lymphadenopathy in All patients compared with controls in all compartments of the neck, accessible to sonographic evaluation. Patients, methods: The retrospective study comprises six patients with AIT, evaluated for enlarged Robbins level VI-LN. We report the findings of fine-needle aspiration Cytology, clonal analysis, histology, and serological testing. The prospective study evaluated the prevalence of lymphadenopathy in 49 consecutive patients with AIT (group 1) and 49 consecutive patients with normal thyroids or nontoxic goiter (group2). Results: In the retrospective study, cytology of paratracheal LN revealed reactive lymphoid hyperplasia in 5/6 of the cases and a centroblastic lymphoma in one patient. The presence of monoclonal lymphatic cells was excluded in 5/6 patients and proven in 1/6 patients. Actual viral-infections were ruled out. In the prospective study All-patients showed significantly more enlarged LN in Robbins level II-IV and VI compared to controls. We found no correlation between lymphadenopathy, age, thyroid volume and nodularity, or autoantibody levels. During follow-up in 34 group 1-patients, lymphadenopathy remained stable in 28 patients, and decreased in 6 patients. Conclusion: Lymphadenopathy in Robbins level II-IV and VI is common in AIT-patients and most probably related to the autoimmune process
