Abstract

The contralateral transmaxillary corridor improves access to anterior petrous apex lesions back to the level of the internal auditory canal without the need to mobilize the paraclival internal carotid artery. In this Video 1, we present the case of 31-year-old female patient who presented with new left abducens palsy during pregnancy. Imaging revealed a heterogeneous enhancing extradural mass within the left petrous apex region extending posterior to the horizontal segment of the petrous internal carotid artery, consistent with chondrosarcoma. Chondrosarcomas are the second most common osseous malignancy but only consist of 0.2% of all intracranial tumors.
