Methods: In past ten years (1975–1985) there were 90 patients with unilateral acoustic tumors were treated by surgery. Among them (4 cases of HAT and 86 cases of nonhypervascular acoustic tumors, NHATs) were retrospectively reviewed and clinical characteristics, radiological and surgical finding were compared. Results: HATs presented at a younger age than NHATs (28±10 vs. 54±17 years old) (P<0.01). MRI showed that HATs was solid, without tumor cyst, and larger than NHATs significantly (P<0.05). The surface of HATs consistently showed multiple flow voids representing large draining veins. The characteristic angiographical findings of HATs were extensive tumor vessels, tumor stains and early filling of draining veins; Vertebrobasilar arteries supplied HATs. The authors preferred the control hypotension anaesthesia to remove HATs and got total resection of 4 cases of HATs successfully. No patients has needed transfusion or suffered any other complications after operation. Conclusion: HATs was a solid tumor presented at young. Angiographical findings may provide characteristic manifestation, and could be managed by control hyper- tension in one-stage surgical approach.展开更多

The patient was a 55-year-old man with hepatitis B virus-related HCC. He presented to our department with a three-month history of increasing left otalgia,and hearing loss with recent fresh aural bleeding. Histopathologic examination indicated that the tumor was secondary to HCC. Although external irradiation was not effective,the tumor was treated with surgical debulking and high dose rate 192 Ir remote afterloading system (RALS) for postoperative intracavitary irradiation. A review of the literature revealed only five other cases of HCC metastasis to the temporal bone,all of which mainly metastasized in the internal acoustic meatus. The present case is the first report of HCC metastasis to the EAC.展开更多
