Multiple Primary Osseous B-Lymphoblastic Lymphoma/Leukemia Shown on Bone Scintigraphy.

Primary osseous B-lymphoblastic lymphoma/leukemia is very rare, especially multiple bones involved. Herein, we reported the bone scintigraphy findings in a 16-year-old adolescent boy with a 20-day history of right thigh pain caused by B-lymphoblastic lymphoma/leukemia. Multiple abnormal MDP-avid foci were noted on 99mTc-MDP bone scintigraphy. Interestingly, the CT images of corresponding lesions were unrevealing. Finally, the B-lymphoblastic lymphoma/leukemia was confirmed by pathology and immunohistochemistry.
