Cranioplasty following decompressive craniectomy is regarded as a relatively simple and safe procedure to protect the brain and improve neurological function. However, some serious complications, such as infection, hematoma, bone resorption, seizure, and epidural or subdural fluid collection may develop after cranioplasty. Among these complications, epidural fluid collection after cranioplasty is not well described and with limited reports on the same. Here, we report recurrent epidural fluid collection after cranioplasty, eventually necessitating the removal of the bone flap. This study discusses the possible pathological mechanisms of this undesirable complication with a review of the literature.
