Listeria monocytogenes encephalitis mimicking Herpes Simplex virus encephalitis: The differential diagnostic importance of cerebrospinal fluid lactic acid levels

“…Pending bacteriologic and virologic laboratory confirmation, an elevated CSF lactic acid is the single key early determinate that should prompt the clinician to begin empiric anti-L. monocytogenes therapy, which is demonstrated by this case. 18,19 The last clinical teaching point is that L. monocytogenes encephalitis may continue for many days before responding to antimicrobial therapy. 3,6,20 The family had given up hope for the patient's recovery early in the course of his illness.…”

Systemic lupus erythematosus (SLE) cerebritis versus Listeria monocytogenes meningoencephalitis in a patient with systemic lupus erythematosus on chronic corticosteroid therapy: The diagnostic importance of cerebrospinal fluid (CSF) of lactic acid levels

“…14 In meningoencephalitis, among patients with no red blood cells in the CSF, L. monocytogenes may mimic hepatic encephalopathy, Legionnaire's disease, or West Nile encephalitis. [15][16][17][18] Levels of lactic acid in the CSF provide a key diagnostic test for the early differentiation of ABM from nonbacterial meningitis. Patients with ABM manifest levels of lactic acid in the CSF at greater than or equal to 6 mmol/L, whereas those with aseptic or viral meningitis manifest levels of lactic acid in the CSF at less than 3 mmol/L.…”

Headache and Tremor: Co-occurrences and Possible Associations

“…In bacterial meningitis headache is almost uniformly present but tremor is uncommon, with the possible exception of Listeria infections of the central nervous system 24,25. Lorber24 reports that movement disorders including tremor are present in 15–20% of patients.…”
