rombencephalitis

BACKGROUND: Listeria monocytogenes (LM) is a gram-positive intracellular bacillus that in immunodeficient patients, children, geriatric patients, pregnant women, and even in healthy individuals can cause central nervous system infection, bacteremia, and other clinical manifestations, becoming a relevant pathogen. MATERIALS AND METHODS: From the Microbiology Service data of 'Gregorio Marañón' Hospital, we selected all positive biological sample cultures for LM from inflammatory bowel disease (IBD) patients, from January 1986 until January 2011...

Rhombencephalitis due to Listeria is a serious and infrequent infection of the brainstem. It principally affects subjects who were previously healthy. It shows itself clinically in two phases: the first with unspecific symptoms, which could last one week, and the second with the appearance of focal neurologic signs at the level of the brainstem. We present the case of a patient with rhombencephalitis due to Listeria that began initially with headache, nauseas and fever and after ten days the patient showed an asymmetrical affection of cranial nerves, cerebellar signs and sensory deficits in the left hemibody...

INTRODUCTION: Infection of the central nervous system by Listeria monocytogenes appears in most cases as acute meningitis which is indistinguishable from other types of acute meningitis. Rombencephalitis is a rare form of neurolisteriosis, localized to the brainstem. The initial non specific symptoms may make early diagnosis difficult. CASE REPORT: We describe the clinical case of a previously healthy woman who had L. monocytogenes infection localized to the brainstem...
