Listeria monocytogenes meningitis appears to have increased in incidence. Although most reported cases of listeriosis involve the central nervous system, brain computed tomography is usually normal. Hydrocephalus is a common complication of tuberculous meningitis, which has a high prevalence in Taiwan. However, patients with L. monocytogenes meningitis rarely develop the complication of symptomatic hydrocephalus. We report a patient with L. monocytogenes meningitis who presented with persistent alteration of consciousness after appropriate antimicrobial therapy. Follow-up brain computed tomography revealed acute hydrocephalus. An Ommaya reservoir was implanted, and daily drainage of the cerebrospinal fluid was performed. The patient improved gradually and his mental status recovered completely 4 days later. This case should remind physicians to be aware of the possible occurrence of hydrocephalus in L. monocytogenes meningitis and that prompt cerebrospinal fluid drainage may achieve a good outcome.



Key words:
