A large abscess was detected on Apr. 1 and was treated immediately with systemic antibiotics. A subsequent scan 10 days later demonstrated that the antibiotic treatment was ineffective, as the abscess volume increased. Following the second scan, an emergency surgery was performed, in which the abscess was drained and the implant completely removed. Subsequent scanning demonstrated a complete clearing of the intracranial infection, with scar tissue visible at the previous site of the abscess.
