Intracranial abscesses are rare lesions with an incidence estimated at 1500-2500 cases per year in the United States.

Treatment options include systemic antibiotic therapy, needle aspiration through a burr hole, and open craniotomy for excision.

The recently introduced IRRAflow self-irrigating catheter system has been used to treat subdural hematomas and intraventricular hemorrhages although research into other applications for this technology is still ongoing.
