Device-associated Central Nervous System Infection Caused by Candida parapsilosis.

Meningitis is a common and life-threatening infection of the central nervous system (CNS) in infants with long-term and disabling sequelae like hydrocephalus. Hydrocephalus is treated by diverting cerebrospinal fluid (CSF) either to another body cavity (via CSF shunt) or externally (via CSF drain) which are prone to infection. Though rare, () is a known pathogen in device-associated CNS infections and has been reported in both, infants and adults. A six-month-old male infant was brought to the hospital with disproportionate head enlargement of three months duration. Magnetic resonance imaging (MRI) was suggestive of gross asymmetrical hydrocephalus. An external ventricular drain (EVD) was placed, and vancomycin and meropenem were started. Four weeks later, he developed a fever with a blocked EVD. Repeat MRI revealed gross asymmetric dilatation of left lateral ventricle along with pneumocephalus in the right periventricular region. A right temporoparietal craniotomy with drainage of a multiloculated abscess was done along with the removal of right EVD and placement of left EVD. CSF showed pan-susceptible and fluconazole was started. Despite treatment, CSF continued to grow through day 10. The EVD was removed, and an Ommaya reservoir along with the ventricular catheter was placed for better interventricular antibiotic administration. After day 13 CSF became sterile. Ommaya reservoir was removed, fluconazole was continued for three weeks, and a ventriculoperitoneal shunt was placed five weeks later. The device-associated CNS infections are insidious with nonspecific manifestations making diagnosis difficult. has been increasing in prevalence, especially in immunocompromised hosts, infants, and in patients with indwelling catheters. Amphotericin B or fluconazole is the usual treatment with excellent outcomes and no mortality. This case underscores the need for suspicion of as a cause of device-associated CNS infections.
