The Clinic, Image And Therapy Of Glomus Jugular Tumor

Objective: To discuss the clinical characters, image figures and therapeutic ways of Glomus Jugular tumor(GJT).Method: 4 cases of GJT finally diagnosed by DSA in clinic were analyzed; and combining with relative literature, the clinic characters, image figures, diagnosis and differential diagnosis, therapy and prognosis of GJT were concluded and summarized.Result: Most of patients with GJT are elderly, generally above 40 years old, most frequently between 60-75. This disease has some heritability. GJT progresses slowly, so the course is long, generally for 4 years, exceptionally for 10 years. The main clinical manifestations are caused by auricular nerve and other cranial nerves injury. If the size of tumor is big enough, the symptoms about cerebellum brainstem and intracranial hypertension may appear . CT, MRI and DSA can all help to diagnose GJT. MRI is especially valuable to the diagnosis,the serpiginous appearance of signal void in tumor and the "salt & pepper" sign were the characteristic MRI appearances . DSA can provide the evidence to the final diagnosis of this disease, which can display definitely the location, the size and the infringing range of tumor. The therapeutic ways of GJT include surgical excision , tumor-blood vessel embolization and radiation.Conclusion: GJT occurs infrequent in clinic, and onsets hidingly. The anatomic structures around it are intricate. Thus it may be easily misdiagnosed. Typical clinical manifestations combined with image examination contribute to its diagnosis. DSA can give the final diagnosis and provide help to surgery therapy. Surgical resection is the most valuable way to cure it. Preoperative embolization is essential to reduce blood.loss during operation. The earlier the operation, the better the prognosis.
