Diagnosis of Lymphomas in Fever of Unknown Origin Cases

Objective:To improve the diagnosis of lymphamas in FUO cases. Methods:Three patients with lymphomas and FUO confirmed by pathology were presented and the relevant literatures were reviewed.Also,laboratory tests,invasive and non-invasive procedures were analysed. Results:18F-FDG PET imaging appears to be a valuable imaging procedure for screening of lymphoma in FUO cases. Lymph nodes biopsy,bone marrow examination and spleen needle biopsy are helpful to identify the disease. Conclusion:The clinical features of lymphomas in FUO cases are insufficient to characterise a disease,and they may be misdiagnosized. Biopsy may then confirm the diagnosis.
