Abstract:
We report two neutropenic patients with Stomatococcus mucilaginosus meningitis and choroid plexus involvement on neuroimaging studies. CT and MR showed abnormal enlargement of the choroid plexus in one lateral ventricle and intense enhancement. In one patient there was edema in the periventricular white matter adjacent to the involved choroid plexus; in both patients there was enhancement of the ependyma.
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.
