“…[1] Furthermore, it is a sensitive modality for early detection of relapse in asymptomatic patients making surveillance 18 F-FDG PET/CT clinically important. [2] Splenic uptake on 18 F-FDG PET can be due to a wide variety of causes such as lymphoma, anemia, granulocyte colony stimulating factor treatment, beta-thalassemia, inflammation and infections. [345678] Splenic uptake, greater than hepatic uptake, is a relatively reliable indicator of lymphomatous involvement of the spleen, in the absence of recent cytokine administration.…”

Malaria masquerading as relapse of Hodgkin′s lymphoma on contrast enhanced ¹⁸ F-fluorodeoxyglucose positron emission tomography/computed tomography: A diagnostic dilemma

18Flurodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) is nowadays routinely used in management of lymphoma patients. We here present a case of Hodgkin's lymphoma which showed 18F-FDG avid splenomegaly on PET/CT done for clinically suspected relapse. Further evaluation by peripheral smear examination revealed malaria. The patient was then started on anti-malarial medications and follow-up PET/CT revealed resolution of hypermetabolic splenomegaly. This report highlights that in endemic regions malaria can cause 18F-FDG avid splenomegaly and might mimic relapse of lymphoma.

Fluoro-deoxy-glucose positron emission tomography/computed tomography in lymphoma: A pictorial essay

et al. 2013

F-18 fluoro-deoxy-glucose (FDG) positron emission tomography/computed tomography (PET/CT) has emerged as a powerful imaging modality in the field of oncology. F-18 FDG PET/CT is now an established tool in the management of lymphoma. This has been shown to be useful in staging, detection of bone marrow involvement (BMI), early response assessment and end of therapy response assessment in lymphoma. Interpretation of F-18 FDG PET/CT in lymphoma is carried out by various qualitative response assessment criteria. London criteria are used for interpretation of interim PET/CT and International Harmonization Project (IHP) criteria are used to interpret PET/CT done after the end of chemotherapy. Quantitative analysis is also found to be useful in assessment of response early after two cycles of chemotherapy in patients with diffuse large B cell lymphoma (DLBCL). This pictorial essay provides few images describing the FDG avidity of lymphoma, patterns of bone marrow uptake and their relevance in predicting BMI, role of staging PET/CT, quantitative analysis in response assessment, example images of response according to London criteria and IHP criteria. Few pitfalls in imaging of lymphoma with PET/CT are also discussed in the images legend.
