Insights

This study details two cases of Stomatococcus mucilaginosus meningitis in neutropenic patients. Neuroimaging revealed choroid plexus and ependymal involvement, highlighting rare complications.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Stomatococcus mucilaginosus is a rare cause of meningitis, particularly in immunocompromised individuals.
  • Neutropenia significantly increases the risk of opportunistic infections, including central nervous system involvement.

Observation:

  • Two neutropenic patients presented with meningitis attributed to Stomatococcus mucilaginosus.
  • Neuroimaging (CT and MR) was performed to assess the extent of central nervous system involvement.

Findings:

  • Abnormal enlargement and intense enhancement of the choroid plexus in a lateral ventricle were observed in one patient.
  • Edema in the periventricular white matter adjacent to the affected choroid plexus was noted in one case.
  • Ependymal enhancement was present in both patients, indicating inflammation of the ventricular lining.

Implications:

  • This case series expands the understanding of Stomatococcus mucilaginosus meningitis presentations.
  • Neuroimaging findings underscore the importance of evaluating choroid plexus and ependymal structures in suspected CNS infections.
  • Early recognition and appropriate management are crucial for neutropenic patients with CNS infections.
