Introduction:
Chondrosarcoma is a tumour with a cartilaginous matrix frequently encountered in long bones and the pelvis with rare sinonasal location.
Patient And Methods:
We report the case of a 25-year-old patient who was referred to us for an extension work-up for sinonasal chondrosarcoma confirmed by anatomopathological examination.
Results:
Facial magnetic resonance imaging (MRI) confirmed by a CT scan showed an osteolytic tumour process of the hard palate and walls of the left maxillary sinus that was locally advanced.
Conclusion:
The sinonasal location of a chondrosarcoma is rare. Characterized by cross-sectional imaging, confirmation was provided by histological assessment.
Learning Points:
The sinonasal location of a chondrosarcoma is rare.A slow-growing tumour with a cartilage matrix in adults, it is revealed mainly by neurosensorial signs and mass effect in its sinonasal location.Radiological characterization includes areas with a weak signal on T1- and T2-weighted images in MRI, not enhanced by gadolinium, corresponding to the cartilage matrix.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
