A case report of B lymphoblastic lymphoma with brain metastases

摘要

Introduction:B lymphoblastic lymphoma (B-LBL) is a rare type of lymphoma that originates from precursor lymphocytes. B-BLB in adults with brain metastases is extremely rare as the disease mainly affects children and adults. Therefore, such a seldom-seen case can easily trigger a dispute regarding clinical diagnosis and treatment.This paper reports the case of a 22-year-old man hospitalized for a head injury that resulted from a physical altercation. Upon admission to the hospital, the patient was diagnosed with a diffuse axonal injury (DAI). Accordingly, the patient receiving follow-up treatments, but died 30 days later. After a systematic necropsy, immunohistochemical staining, radiological consultation, and a complete review of the clinical dates, we defined the case as a brain metastasis of B lymphoblastic lymphoma. Imaging results of the intracranial lymphoma were nearly indistinguishable from DAI during the acute phase, which led to misdiagnosis and incorrect treatment for B-LBL.
