RESUMEN
OBJECTIVE: Brain abscesses are life-threatening and sometimes difficult to detect. A brain abscess after placement, manipulation of a bone anchored hearing aid, or a periauricular implant for fixation of an ear prosthesis has never been reported in the literature. PATIENT: A 42-year-old man suffered from a right-sided temporodorsal brain abscess after change of a bone anchored hearing aid abutment. The fixture itself had been inserted 8 years before without any complications in the peri- or postoperative period. A CT-guided puncture of the abscess could be performed via the screw-hole in the temporal bone after removal of the fixture, and the patient was treated with antibiotics. RESULTS: The outcome of the procedure was good without neurologic deficits for the patient. CONCLUSION: The insertion of periauricular screw implants bears the risk of meningeal lesions as well as a small risk of purulent intracranial and intracerebral complications perioperatively or in the context of later manipulations. Minimally invasive therapy of such brain abscesses can be performed by removal of the foreign body, CT-guided puncture, and antibiotic medication.
