Methods: In this retrospective study of 281 cases of lymphomas of various histologies, we illustrate the spectrum of PET/CT features of extranodal lymphoma (ENL) of commonly involved organs and compare our result with the literature. Result: Extranodal appearance in lymphoma is strikingly varied. Diffuse large B cell lymphoma (DLBCL) is the commonest histological subtype and gastrointestinal tract is the commonest anatomical subsite in NHL. Skeletal system is the commonest site for involvement in HD. Conclusion: A broad spectrum of extranodal organs is involved in various subtype of lymphoma which can be depicted in PET-CT in the most appropriate manner. Familiarity with the pattern of involvement is essential for comprehensive management.}, keywords = {Hodgkin's disease,Lymphoma,PET/CT}, url = {https://aojnmb.mums.ac.ir/article_2304.html}, eprint = {https://aojnmb.mums.ac.ir/article_2304_2e580096ed7fa1b2c38f6b6bab30ee9b.pdf} }
