Abstract

Chondrosarcomas are a heterogeneous group of malignant bone tumours that share the production of the chondroid matrix in common. At the base of the skull, they are most commonly found in the region of the various synchondroses with an affinity for the petroclival fissure, they are locally invasive tumours, with little capacity to perform metastasis. The age group affected is variable, however, they frequently occur in middle-aged adults. Its clinical manifestation depends on the location and local extent; headache or paralysis of cranial nerves, particularly of the VI nerve is a frequent sign. As the petrous apex cannot be viewed directly, imaging studies such as computed tomography and magnetic resonance imaging play an important role in the evaluation of injuries. We present a case of a 36-year-old patient with chondrosarcoma of petroclival syndromes without visual changes. For the identification of this pathology, a battery of imaging tests was used and the diagnosis was made assertively, preserving the best choices for the treatment of the patient.
