Abstract: listeria monocytogenes infections can involve the central nervous system in the form of a rhomboencephalitis. three possible cases of rhomboencephalitis by listeria monocytogenes are reported (2 females, aged 44 and 49 and a man of 36 years old). the three cases were preceded by an unspecific prodrome of headache, vertigo and fever in absence of a meningeal syndrome. the neurological stage was defined by the unilateral involvement of cranial nerves and the cerebellum and a clear inflammatory cerebrospinal fluid (csf) with the presence of polymorphonuclear leukocytes, and normal glucose and protein levels. a magnetic nuclear resonance (mri) showed the appearance of characteristic images, present in the bulboprotuberancial region. these images are one of the most constant features of this disease, reported in the literature. the early diagnosis of rhomboencephalitis was based on the clinical picture, the study of the csf and the mri, allowing the use of antimicrobials, prior to microbiological identification. therefore, the risk of brain stem and cardiac complications of the disease is reduced (rev méd chile 2003; 131: 921-8)

Abstract: Hyponatremia is common in patients with severe neurological diseases and is often secondary to a syndrome of inappropriate antidiuretic hormone secretion (SIADH). However, in some patients, hyponatremia is due to cerebral salt wasting syndrome (CSWS). SIADH and CSWS treatments are opposite and misdiagnosis can lead to increased morbidity and mortality. We report a 52 years old female with a rhom-boencephalitis caused by Listeria Monocytogenes (LM), ventriculitis and abscesses in cerebellum and brainstem. It was associated with hyponatremia, hypotension, increased natriuresis, hypouricemia, and low creatinine and blood urea nitrogen levels. Large amounts ofsodium were needed and the condition persisted after hospital discharge. Hyponatremia is common in central nervous system involvement by LM, however we are not aware of CSWS reports of this condition.

Abstract: An unusual number of cases of rhomb encephalitis have occurred in Chile because of the increased frequency of infections caused by Listeria monocytogenes. We report three females aged 36, 40 and 55 years, with the disease. All presented with a prodrome characterized by headache, nausea, vomiting and fever, followed by ataxia and unilateral palsies of the third, seventh and twelfth cranial nerves. One patient presented also a hemi-hypoesthesia. Magnetic resonance showed lesions in the posterior aspect of the brain stem, specifically in relation to the floor of the fourth ventricle. Blood cultures were positive for Listeria monocytogenes.

Abstract: Las manifestaciones en el sistema nervioso central por Listeria monocytogenes son variadas, e incluyen desde la meningitis hasta las presentaciones más infrecuentes como los abscesos cerebrales. éstos son clínicamente indistinguibles de otros tipos de abscesos y sugieren una alteración de la inmunidad celular. Se describe el caso de una mujer seropositiva para el virus de la inmunodeficiencia humana (VIH) que consultó al servicio de urgencias con un síndrome convulsivo tónico-clónico generalizado de un mes de evolución y deterioro progresivo de su estado de conciencia. En el estudio del líquido cefalorraquídeo se encontró pleocitosis linfocitaria, con elevación de las proteínas e hipoglucorraquia. En el estudio del sistema nervioso central por resonancia magnética se observaron múltiples lesiones hipodensas que se realzaban con el medio contraste. Se aisló L. monocytogenes en el cultivo del líquido cefalorraquídeo. Después de un esquema de tratamiento antibiótico específico asociado a esteroides, los síntomas neurológicos mejoraron y, concomitantemente, se observó una disminución progresiva hasta la desaparición de las lesiones en el seguimiento imaginológico del sistema nervioso central. L. monocytogenes es causa de abscesos cerebrales en pacientes inmunosuprimidos, en especial, con VIH sin terapia antirretroviral o sin profilaxis con trimetoprim-sulfametoxazol. The manifestations of Listeria monocytogenes central nervous system infection are wide, ranging from meningitis to cerebral abscesses. Those are clinically indistinguishable from other forms of cerebral abscesses. We are describing a HIV positive woman who presented with generalized tonicclonic seizures, progressive alter mental status, evidence of lymphocytic pleocytosis and multiple hypodense lesions that enhanced with contrastae on imaging studies (CT and MRI) Listeria monocytogenes was isolated of cefaloraquid liquid cultures. After a specific antibiotic treatment regimen associated with steroids, improved neurological symptoms and concomitant documented a progressive decrease until disappearance of the lesions in the CNS imaging follow. Listeria monocytogenes is a cause of brain abscesses in immunosuppressed patients especially HIV patients without antiretroviral therapy and without prophylaxis with trimethoprim / sulfamethoxazole.

Abstract: infections caused by listeria monocytogenes are usually found in cattle and occasionally appear in humans, particularly pregnant women and immunocompromised individuals. peritonitis by listeria monocytogenes is a rare but dangerous condition that must be recognized early, since it requires a specific treatment. we report a 31 year-old male with alcoholic cirrhosis that developed ascites with abdominal pain and fever. the peritoneal fluid culture yielded listeria monocytogenes. the patients was initially treated with cefotaxim and later with ampicillin and levofloxacin. the patient voluntarily abandoned treatment and died at home two weeks later

Revista médica de Chile , 2008, DOI: 10.4067/S0034-98872008001100012
Abstract: ascitic and pleural fluids infection by listeria monocytogenes is uncommon. the association of spontaneous bacterial peritonitis and empyema caused by this microorganism has been seldom reported. a 61 year-old male with an alcoholic cirrhosis and an upper right ?obectomy for a lung cáncer, consulted because of an exacerbation of dyspnea, abdominal pain and fever. listeria monocytogenes was isolated from ascitic and pleural fluids and from blood cultures. he was successfully treated with ampicillin and a chest tube for drainage.

Abstract: l. monocytogenes infections are infrequent. sepsis in pregnant women and newborns and central nervous system infections in the elderly are the most common clinical manifestations. we report a 61 years old woman with diabetes mellitus and a child b hepatic cirrhosis, admitted for persistent fever. blood cultures were positive for listeria monocytogenes. cerebrospinal fluid was normal and sterile. she was treated with ampicillin and amikacin with a good response. control blood cultures were negative. she was discharged 14 days after in good conditions
