Summary
Desmoid-type fibromatosis (DTF) is a rare locally aggressive soft tissue neoplasm without metastatic potential. Here, we report a very rare sporadic case of an intracranial supratentorial extradural DTF measuring 82 mm in a 1-year-old girl, that recurred twice following surgery over the course of 16 months, requiring two other surgeries. In three surgeries, we resected a huge tumor with the dura which was thought to be tumor origin and removed this tumor infiltrated the frontal skull base by drilling widely. Furthermore, we treated the tumor invading the bone flap using liquid nitrogen for 20 minutes, and subsequently used it to perform a cranioplasty. This tumor has not recurred for past 8 months. DTF invading the skull base is prone to recurrence, and liquid nitrogen treatment is considered to be effective in pediatric patients, who need cranioplasty with tumor-infiltrating autologous bone flaps.
