Magnetic resonance imaging showed an enhancing lobulated lesion subjacent to a right frontal burr hole, surrounded by vasogenic edema with mass effect and midline shift. Nine years earlier, she had had a triple bolt inserted to monitor intracranial pressure after sustaining a traumatic brain injury. Surgicel was used to control bleeding during insertion. Colocation of the lesion with the position of triple bolt 9 years earlier raised suspicion for gossypiboma. However, the minor nature of the surgery and the length of time since surgery to presentation placed this case well outside the range of cases reported in the literature. The lesion was resected en bloc with no recurrence 18 months later. Histological examination revealed the presence of foreign material. However, given its minute size, confirming its nature was not possible.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Lessons<\/jats:title>\n                    <jats:p>The authors show that gossypibomas can occur following a relatively minor procedure and remain clinically and radiologically silent for much longer than previously reported.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case21479","type":"journal-article","created":{"date-parts":[[2022,2,21]],"date-time":"2022-02-21T02:07:03Z","timestamp":1645409223000},"source":"Crossref","is-referenced-by-count":5,"title":["Intracranial gossypiboma 9 years after intracranial pressure bolt insertion: illustrative case"],"prefix":"10.3171","volume":"3","author":[{"given":"Ryan T.
