Small Rounded B-cell Lymphoma of Bone Presented by Limp, With a Positive Multifocal 99 mTc MDP Bone Scintigraphy Pattern and a Negative 99 mTc HMPAO-labeled Leukocytes StudyPerez, Ruben Hernandez MD; Alonso Farto, Juan Carlos MD, PhD; Arias, Isabel Almoguera MD; Regi, Amanda Rotger MD; Perez Vazquez, Jose Manuel MD, PhDJournal of Pediatric Hematology/Oncology: June 2008 - Volume 30 - Issue 6 - p 443-446 doi: 10.1097/MPH.0b013e318169169a Original Articles Abstract Author Information In this article, we present a rare case of B-cell bone lymphoma in a child with multifocal asymptomatic lesions detected by bone scintigraphy and a chronic clinical history characterized by limping and fever episodes for over a year. Initially, multifocal osteomyelitis was suspected and antibiotic therapy was administered with no clinical improvement. The biopsy of the main lesion in the left distal femur along with bone marrow cytology established the final diagnosis. This rare case illustrates the utility of routinely low cost-effective nuclear medicine studies like whole body bone scan and 99 mTc hexamethylpropyleneamine oxime-labeled leukocytes to orientate similar cases to a correct diagnosis.
