S.B. Ankara Numune Eğitim ve Araştırma Hastanesi, 2. Nöroşirürji Kliniği, Ankara, Türkiye Postoperative abducens paresis was reported after resection of sphenoid wing meningioma or similar tumors with paracavernous extension. The true pathogenesis of this paresis was still unclear. Although long course of abducens nerve is speculated to be the main factor, trochlear nerve which has a longer course than abducens nerve was less commonly involved, hence intracranial pressure changes and other anatomical factors may have a major role. Here we report a 44-year-old woman who was operated for a huge sphenoid wing meningioma and abducens nerve paresis was noted at the postoperative period. This finding was probably associated with the manipulations of tumor during resection or early changes in intracranial flow dynamics since early MR scans helped to rule out ischemic reasons or other possible changes at the tumor lodge.
