Summary
A rare brain tumor complication occurred when a meningioma developed a bacterial abscess. This case highlights Proteus mirabilis as a cause of intratumoral abscess in an immunocompetent patient.
Area of Science:
- Neurology
- Neurosurgery
- Infectious Diseases
Background:
- Meningiomas are typically benign tumors of the meninges.
- Intratumoral abscesses within meningiomas are exceedingly rare.
Observation:
- A 78-year-old immunocompetent woman presented with right lower-extremity paralysis following a focal seizure.
- Neuroradiological imaging identified a parasagittal meningioma.
Findings:
- Surgical resection revealed a bacterial abscess within the meningioma, caused by Proteus mirabilis.
- This represents the second reported instance of an intratumoral abscess in a meningioma.
Implications:
- This case expands the known spectrum of meningioma complications.
- It underscores the importance of considering infectious etiologies even in immunocompetent individuals presenting with neurological deficits and brain tumors.
