Chondrosarcoma of the head and neck region is a rare disease, representing approximately 0.1% of all head and neck neoplasms. We present a case of a 30 year old male who presented with swelling in the right retroauricular region since 4 years. Magnetic resonance imaging and computed tomography showed lesion with its epicentre in the post styloid compartment of right parapharyngeal space with superior extent around the petrous apex. The surgical procedure considered was excision. Surgical excision was challenging in view of difficult surgical access due to close and intricate relation with neurovascular structures of head and neck and an unsual pattern of spread.
头颈部软骨肉瘤是一种罕见疾病，约占所有头颈部肿瘤的0.1%。我们报告一例30岁男性病例，该患者4年来右侧耳后区域一直肿胀。磁共振成像和计算机断层扫描显示病变位于右咽旁间隙茎突后间隙，中心部位在该间隙，向上延伸至岩尖周围。考虑的手术方式为切除。鉴于该病变与头颈部神经血管结构关系密切且复杂，手术入路困难，同时其扩散模式不寻常，手术切除具有挑战性。
