Transient immunologic defect in a case of Listeria rhombencephalitis

We report a case of Listeria rhombencephalitis in a previously healthy 60-year-old man. Listeria rhombencephalitis is a rare but well-defined clinical syndrome of lower brain-stem involvement caused by Listeria monocytogenes. Contrary to other listerioses, rhombencephalitis has been mainly observed in patients without predisposing conditions. In our case, however, findings of a detailed immunologic study, performed three months and one year, respectively, after clinical onset of Listeria rhombencephalitis manifestations, showed a transient cellular immunity defect, not associated with any other apparent disease.
