[Clinical study of chondrosarcoma in the jugular foramen].

Objective: To explore the diagnosis and surgical treatment of chondrosarcoma in the jugular foramen (JF). Method: This study lies on the retrospective analysis about 72 patients with secondary hyperparathyroidism who had parathyroid gland resection in our hospital from 2010 to 2017. All of 72 cases are examined by color doppler ultrasound,99mTC-MIBI nuclide imaging and magnetic resonance imaging. According to the gold standard pathological diagnosis after surgery, we compute the sensitivity and the specificity of various imaging examination and analyse these statistics by rate card square test with SPSS 19.0 software. Result: The main complaints in the patients included hearing loss, facial palsy and tinnitus. All patients achieved total removal with IFTA-A as initial treatment. Three cases underwent facial nerve grafting and preoperative cranial nerve dysfunction didn't aggravate in our cases. No recurrence or major complication has been identified till the latest follow up. Conclusion: Chondrosarcoma in the JF is a rare entity. Misdiagnosis frequently occurs in clinical practice. Special attention should be paid to the clinical characteristics and radiological findings when encounters a lesion in the jugular foramen. It is believed that the complete resection of the tumor should be the initial choice for patients with chondrosarcoma in the JF.
