(See "Aseptic meningitis in adults".) <span>For patients who present with symptoms of rhombencephalitis (focal involvement of the brainstem), Listeria is the most common infectious cause; however, noninfectious causes can also result in a similar clinical presentation. In one series of 97 patients with rhombencephalitis, most cases (n = 31) were of unknown etiology, and multiple sclerosis (n = 28) was the most common identified cause overall [31].

Other noninfectious conditions that can cause brainstem and/or cerebellar lesions include sarcoidosis, systemic rheumatic diseases (Behçet syndrome, systemic lupus erythematosus, relapsing polychondritis), lymphoma, and paraneoplastic syndromes and should be considered if infectious etiologies, including Listeria have been ruled out or considered unlikely.

Other infectious etiologies of encephalitis that may involve the brainstem and/or cerebellum include herpes simplex virus [32], Lyme disease, Epstein-Barr virus, and Brucella. In patients with an immunocompromising condition, additional considerations include toxoplasmosis, cryptococcosis, and reactivation of John Cunningham virus. Tuberculosis is also a possible cause of rhombencephalitis in patients with relevant epidemiologic risk. The distinction is usually made based on culture or molecular testing of CSF. In some cases, empiric treatment for some of these other etiologies is warranted pending microbiologic results.

Pregnant patients — The incidence of listeriosis associated with pregnancy is approximately 10 times higher than in the general population [15,41-43].

Clinical manifestations — Listerial syndromes in pregnancy include febrile gastroenteritis and bacteremia. They are diagnosed most commonly during the third trimester.

Maternal infection may present as a nonspecific, flu-like illness with fever, myalgia, abdominal or back pain, nausea, vomiting, or diarrhea [44]. Listeria infection may be mild and resolve without therapy, and the diagnosis missed if blood cultures are not obtained [5,14]. Among pregnant women with listeria bacteremia, CNS involvement is relatively uncommon [22].

Outcomes for pregnant women with Listeria are typically good; however, fetal and neonatal infections can be severe, leading to fetal loss, preterm labor, neonatal sepsis, meningitis, and death.

Central nervous system involvement of L. monocytogenes most commonly manifests with meningoencephalitis, which ranges from a mild illness with fever and mental status changes to a fulminant course with coma. Many patients do not have signs of meningeal irritation. Less common manifestations include cerebritis (which infrequently progresses to brain abscess) and rhombencephalitis.
