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.
引言
软骨肉瘤是一种具有软骨基质的肿瘤，常见于长骨和骨盆，鼻窦部位罕见。
患者与方法
我们报告一例25岁患者，因鼻窦软骨肉瘤接受进一步检查，经解剖病理学检查确诊。
结果
面部磁共振成像（MRI）经CT扫描证实，显示硬腭和左上颌窦壁有溶骨性肿瘤病变，局部进展。
结论
鼻窦部位的软骨肉瘤罕见。通过横断面成像进行特征描述，并经组织学评估得以确诊。
学习要点
鼻窦部位的软骨肉瘤罕见。在成人中，它是一种生长缓慢、具有软骨基质的肿瘤，主要表现为鼻窦部位的神经感觉症状和占位效应。放射学特征包括在MRI的T1加权和T2加权图像上信号较弱的区域，钆增强扫描无强化，对应软骨基质。
