Ventriculitis is inflammation of the ependymal lining of the ventricular system. Ventriculitis is a serious condition characterized by inflammation and infection of the ventricles, which are fluid-filled cavities within the brain.
It is a rare but serious intracranial infection.
Uncommonly, ventriculitis is a complication of meningitis or occurs spontaneously in immunocompromised patients 1).
Healthcare-associated ventriculitis.
Klebsiella pneumoniae ventriculitis.
The clinical course of ventriculitis is typically indolent and non-specific, and early diagnosis and treatment are important to improve prognosis.
The cure rate was 73.3%. Of note, the mean period to sterilize the CSF after appropriate IVT antibiotic treatment was 6.6 days. There were no incidents of seizure or chemical ventriculitis during this IVT therapy.
The findings of this study suggest that IVT antibiotic therapy is a useful option in the treatment of post neurosurgical GNBM or ventriculitis, especially for those with a treatment-refractory state 2).
A 53-year-old previously well man who presented with a collapse after a 4-day history of severe non-specific headache and vomiting. His initial Glasgow Coma Score (GCS) was 7/15 (E1V1M5), temperature was 38.2 °C, and he was intubated. Empirical ceftriaxone and acyclovir were commenced for suspected encephalitis. Cranial CT revealed intraventricular hyperdense areas in bilateral occipital horns and hydrocephalus, suggestive of spontaneous hemorrhage (39–48 Hounsfield units) (Fig. 1). He was transferred to our Neurosurgery Unit. CT angiogram excluded intracranial vascular abnormalities. Blood tests showed neutrophilia (26.5 × 109 /l) and raised C-reactive protein (260.5 mg/l). Following extubation 4 h later, the patient’s GCS improved to E4V1M6. Cerebrospinal fluid (CSF) from a lumbar puncture was turbid; opening pressure was low; glucose was 2.2 mmol (serum glucose 5.9 mmol); microscopy showed pleocytosis (4105 × 106 /l, polymorphs 92 %), and presence of Gram-negative diplococci. Nuclei acid test and polymerase chain reaction test confirmed Neisseria meningitides serogroup B. In retrospect, the intraventricular materials were suppurative substance. On day 2, the patient’s GCS returned to 15. Tests for immunodeficiency, including HIV test, were negative. He completed a 10-day course of ceftriaxone. On day 10, a repeat scan showed complete resolution of the intraventricular purulent material. On day 12, his inflammatory markers normalized, and he was discharged with a full neurological recovery and returned to work 6 weeks later 3).
