Cartilaginous tumors of the mid-face and the skull base are rare.
For the first time, a case report of a chondroma of the base of the ear in a 56-year-old woman is presented. In 1974 the patient developed a facial nerve paralysis while she was pregnant. Twenty-two years later the patient developed persistent headache and CT studies of the head were obtained, which showed an extensive tumorous lesion located at the base of the ear. A tumor was resected through an otoneurosurgical approach. The histological examination showed a chondroma.
Even the rare diagnosis of a chondroma should be considered for a differential diagnosis of skull base tumors.
中面部和颅底的软骨肿瘤较为罕见。
首次报告了一名56岁女性耳部基底软骨瘤的病例。1974年，该患者在怀孕期间出现面神经麻痹。22年后，患者出现持续性头痛，并进行了头部CT检查，结果显示耳部基底有广泛的肿瘤性病变。通过耳神经外科手术方法切除了肿瘤。组织学检查显示为软骨瘤。
即使是软骨瘤这种罕见的诊断，在颅底肿瘤的鉴别诊断中也应予以考虑。
