A primary central nervous system lymphoma (PCNSL) presenting with massive hemorrhage is a rare occurrence that is difficult to distinguish from a high-grade glioblastoma. Comprehensive descriptions of the imaging characteristics of such tumors have not yet been reported. Herein, we reported a case of a PCNSL with massive hemorrhage by presenting the imaging features of computed tomography (CT) imaging and structural and perfusion magnetic resonance imaging (MRI).
A 48-year-old man presented with headache lasting for 10 d. CT of the brain showed a round, heterogeneous, high-density lesion with surrounding edema in the right temporal lobe. For further diagnosis, a series of MRI examinations of the brain were subsequently performed, and a hemorrhagic lesion with ring-like enhancement was determined. The whole lesion was relatively hypoperfused on arterial spin labeling images. Surgical resection of the lesion and histopathological examination confirmed that the lesion was a diffuse large B-cell lymphoma with massive hemorrhage.
PCNSLs with hemorrhage occur very rarely, and structural and perfusion MRI examinations are requested exceedingly rarely. This case provided insight into some characteristics of a hemorrhagic lymphoma on CT and MRI examinations. Perfusion MRI examination may be useful for the differential diagnosis of PCNSLs and other brain tumors.
Core tip: Primary central nervous system lymphoma (PCNSL) presenting with massive hemorrhage is a rare occurrence that is difficult to distinguish from a high-grade glioblastoma. Little is known about its imaging features, especially multimodal magnetic resonance imaging (MRI) findings. Here, we report on the computed tomography and MRI findings of PCNSL in a 48-year-old man. To the best of our knowledge, this is the first report with detailed computed tomography and MRI findings in hemorrhagic PCNSL and could provide useful information for the preoperative diagnosis.
