190 Possible Causes for Lymphocytic Infiltration of the Brain

  • Middle Cerebral Artery Occlusion

    Evidence suggests that brain infiltration of lymphocytes contributes to acute neural injury after cerebral ischemia.[ncbi.nlm.nih.gov] In addition, brain-infiltrating lymphocytes were observed in post-mortem brain sections from patients during the late stage of ischemic stroke.[ncbi.nlm.nih.gov] However, the spatio-temporal dynamics of brain-infiltrating lymphocytes during the late stage after cerebral ischemia remains unclear.[ncbi.nlm.nih.gov]

  • Encephalopathy

    Histopathology, reported in three, showed perivascular predominantly CD8 lymphocytic infiltrates in the brain.[ncbi.nlm.nih.gov] […] showed: raised CSF protein; pleocytosis; raised CSF:peripheral blood mononuclear cell HTLV-1 proviral load ratio; and MRI either normal or showing white matter changes in brain[ncbi.nlm.nih.gov]

  • Encephalitis

    Histopathology, reported in three, showed perivascular predominantly CD8 lymphocytic infiltrates in the brain.[ncbi.nlm.nih.gov] These cells infiltrate the arachnoid membrane and the brain diffusely but are more concentrated around blood vessels.[neuropathology-web.org] […] showed: raised CSF protein; pleocytosis; raised CSF:peripheral blood mononuclear cell HTLV-1 proviral load ratio; and MRI either normal or showing white matter changes in brain[ncbi.nlm.nih.gov]

  • Cerebral Hemorrhage

    The autopsy revealed atypical lymphocytes infiltrating the brain and meninges, which were positive for B-cell-associated antigens and EBV-encoded RNA, and thus EBV-associated[ncbi.nlm.nih.gov]

  • Bartonella Henselae

    Autopsy revealed perivascular lymphocytic infiltrates and microglial nodules in the brain.[ncbi.nlm.nih.gov]

  • Meningitis

    Microscopic examination of these sites revealed extensive fibrotic tissue with a chronic inflammatory infiltrate containing small lymphocytes, plasma cells and rare eosinophils[path.upmc.edu] The cervical spine and thoracic cord are more commonly involved, and intracranially, it's typically seen along the base of the brain.[path.upmc.edu]

  • Idiopathic CD4 Lymphocytopenia

    At autopsy, inflammatory cells, CD8( ) lymphocytes and abundant macrophages but not CD4( ) lymphocytes were infiltrating the meninges at the base of the brain.[ncbi.nlm.nih.gov]

  • Epstein Barr Virus

    […] brachium, and diffuse white matter in magnetic resonance imaging (MRI), together with CD3 T-lymphocytic inflammatory infiltration in perivascular and parenchymal area revealed[ncbi.nlm.nih.gov] Brain biopsy showed perivascular lymphocytic infiltration in the parenchyma and meninx with EBV-encoded small RNA (EBER).[ncbi.nlm.nih.gov] […] by bilateral parietal lobe brain biopsy.[ncbi.nlm.nih.gov]

  • Cryptococcal Meningitis

    At autopsy, inflammatory cells, CD8( ) lymphocytes and abundant macrophages but not CD4( ) lymphocytes were infiltrating the meninges at the base of the brain.[ncbi.nlm.nih.gov] A postmortem examination of the brain revealed degenerative lesions, especially at the cerebral white matter and cortex adjacent to the leptomeninges abundantly infiltrated[ncbi.nlm.nih.gov] In the affected cerebral deep white matter, perivascular infiltration of lymphocytes was prominent in coexistence with reactive astrocytes and vascular proliferation, but[ncbi.nlm.nih.gov]

  • Cytarabine

    No infiltration of leukemia cells was seen. After 2 months, brain MRI findings were normal.[ncbi.nlm.nih.gov] Cerebrospinal fluid (CSF) examination revealed an increase in the number of cells to 31 mm(-3); the majority were lymphocytes.[ncbi.nlm.nih.gov] Magnetic resonance imaging (MRI) of the brain revealed widespread areas of white matter edema.[ncbi.nlm.nih.gov]
