A 75-year-old man was admitted because of a spontaneous rhinorrhoea without
a previous history of head injury. Computed tomography showed bone rarefac
tion of the floor of the middle cranial fossa and magnetic resonance imagin
g demonstrated a right temporal encephalocele. This was treated via extradu
ral approach, and the bone defects were plugged with temporalis fascia, mus
cle and the fibrin glue. No recurrence of rhinorrhoea was observed at the f
ollow-up (1 year).
