Radiographic pattern of extra-nodal non-Hodgkin's lymphoma.

Diffuse large B-cell lymphoma is a Non-Hodgkin's lymphoma (NHL), which has diverse manifestations. Extra-nodal NHL is extremely rare entity. Diagnosis, staging and treatment plan of the patient depends on the clinical findings and radiographic investigations. Positron emission tomography computed tomography (PET CT) scan helps in localization of the lesion and also for posttreatment restaging. Here we are presenting a case report of a 21-year-old patient with diffuse large B-cell lymphoma. This case report highlights the importance of imaging for localization of the lesion and posttreatment evaluation of the lesion. [ABSTRACT FROM AUTHOR]
