One patient with NMDA antibody positivity was finally diagnosed with anti-NMDA receptor encephalitis; while another patient with characteristic MRI findings, CSF pathology findings, and concomitant lung carcinoma was diagnosed with carcinomatous meningitis
with leptomeningeal metastasis, and another with PCR positivity for Brucella DNA was diagnosed with Brucella encephalitis.
Transitional cell carcinomatous meningitis
after M-VAC (methotrexate, vinblastine, doxorubicin, and cisplatin) chemotherapy.
1,2) Neuroradiological findings of metastatic lesions include lepto men ingeal involvement and carcinomatous meningitis
,3 miliary cerebral metastases, (4) and larger single or multiple densities, some with central necrosis, with or without hemorrhagic transformation.
Bacterial, fungal, or carcinomatous meningitis
would be determined by CSF analysis.
A case of aseptic meningitis was defined as an illness with onset from June 1 to September 30, 2001; cerebrospinal fluid (CST) cell count of >5 leukocytes per milliliter; negative CSF bacterial cultures; and no physician or laboratory documentation of bacterial, fungal, or parasitic central nervous system (CNS) disease, cerebral hemorrhage, carcinomatous meningitis
, or cerebral vasculitis.
