Background:
Granuloma induced by silicone plate is rare. We present a case of silicone plate-induced granuloma in the sellar and suprasellar region confirmed by histologic examination at surgery.
Case Description:
A 31-year-old woman suddenly complained of severe headache, polyuria, and visual disturbance 8 years and 9 months after an initial transsphenoidal surgery for pituitary adenoma. At surgery, granuloma and hematoma around the dimethylpolysiloxan (silicone) plate, which had been placed on the sella floor at the initial surgery, were found. Postoperative course was uneventful.
Conclusions:
Our presented case showed one of the disadvantages for silicone placement for repairing the sella floor, and the diagnostic possibility of silicone-induced granuloma in the sellar region.
