Abstrakt: Abducens nerve schwannomas are incredibly rare, with very few cases being reported previously. Our patient is the first to have been treated through use of an endoscopic endonasal approach. A 61-year-old woman presented with diplopia over a 1-year period. Magnetic resonance imaging identified a 2.8-cm lesion expanding into her right sphenoid sinus. She underwent an endoscopic endonasal approach for histological diagnosis and clearance of the lesion. Intraoperative exploration found the lesion to be originating from Dorello canal. Histological analysis confirmed a benign schwannoma. Following a multidisciplinary case review, we have followed a conservative approach and she remains well on radiological surveillance. In patients presenting with a sixth nerve palsy/paresis and a concomitant sphenoid lesion, clinicians should consider an abducens schwannoma as a possible diagnosis.
