SILICONE PLATE-INDUCED GRANULOMA PRESENTING PITUITARY APOPLEXYLIKE SYMPTOMS - CASE-REPORT

BACKGROUND Granuloma induced by silicone plate is rare. We present a c ase of silicone plate-induced granuloma in the sellar and suprasellar region confirmed by histologic examination at surgery. CASE DESCRIPTIO N A 31-year-old woman suddenly complained of severe headache, polyuria , and visual disturbance 8 years and 9 months after an initial transsp henoidal surgery for pituitary adenoma. At surgery, granuloma and hema toma around the dimethylpolysiloxan (silicone) plate, which had been p laced on the sella floor at the initial surgery, were found. Postopera tive course was uneventful. CONCLUSIONS Our presented case showed one of the disadvantages for silicone placement for repairing the sella fl oor, and the diagnostic possibility of silicone-induced granuloma in t he sellar region.
