We present a case of wide-necked giant aneurysm located at the P1-P2 segment of the posterior cerebral artery. The initial goal for treatment of the aneurysm was hemodynamic flow redirection with subsequent thrombosis so the procedure and involved stent placement to the neck of the aneurysm without any filling material. During follow up, significant in-stent stenosis due to intimal hyperplasia was found at the 6th month on digital subtraction angiography. Regression of in-stent neointimal stenosis at the 18th month and a total disappearance at the 76th month were observed on follow-up angiograms. Illustrating the reversibility of neointimal hyperplasia during a long follow up period was the main goal of this case report. Keywords : Intracranial stent, Aneurysm, Neo-intimal hyperplasia
