Meningioma associated with abscess formation--a case report

Area of Science:

• Neurology
• Neurosurgery
• Infectious Disease

Background:

• Meningiomas are typically benign tumors arising from the meninges.
• Intracranial infections, such as abscesses, present significant diagnostic and therapeutic challenges.
• The simultaneous occurrence of meningioma and abscess is exceptionally rare.

Observation:

• A 38-year-old male presented with symptoms indicative of elevated intracranial pressure and intracranial infection.
• Imaging revealed a right temporal pole mass lesion.
• The patient underwent surgical removal of the mass.

Findings:

• Histopathological examination confirmed the mass as a meningioma.
• Cultures from the tumor and surrounding white matter yielded Group B Streptococcus and Peptostreptococcus.
• The likely etiology was hematogenous spread of bacteria secondary to recent dental procedures.

Implications:

• This case highlights the importance of considering infectious etiologies in the differential diagnosis of brain tumors.
• Prompt diagnosis and surgical intervention are crucial for managing such complex cases.
• Understanding potential routes of infection, like dental work, is vital for preventing complications.
