We report a case of hyper vascular metastatic thyroid carcinoma of the jugular fora-men simulating a glomus jugulare tumor. Computed tomography(CT) revealed areas of irregular lytic bony destruction of the left jugular foramen, as well as characteristic in vasion routes of a glomus jugulare tumor. Magnetic resonance(MR) imaging and angiography demonstrated a hypervascular mass similar to a glomus tumor.

Glomus jugulare tumors are usually slow growing, but highly vascularized tumor. The authors report the case of huge glomus jugulare tumor treated by surgical resection with preoperative embolization. A 32-year old male patient presented with a history of right-sided facial palsy and hearing disturbance. Magnetic resonance imaging demonstrated an irregular large mass with multiple signal voids in the right temporal area. Prior to surgical excision of tumor, the patient underwent superselective embolization. Embolization of the tumor and its dominant feeding arteries were achieved. Six days later, the patient underwent an infratemporal fossa approach to remove the tumor. The patient did well postoperatively except CSF leakage that was treated successfully by dura repair. We discuss the usefulness of preoperative embolization and infratemporal approach for the huge glomus jugulare tumor.

Chondrosarcoma of the temporal bone is a rare lesion. Clinically it has been confused with chordoma, glomus jugulare tumor and meningioma, among other conditions, and due to its anatomic location, cranial nerve palsy is frequently observed. We report a case involving a 50-year-old woman with chondrosarcoma of the temporal bone.

Jugulotympanic paragangliomas (JTPs) known as glomus tumors, are neoplasms of variable invasiveness that arise from the paraganglia situated around the jugular bulb or middle ear. We now report a rare case of JTP in an 18-year-old male. Preoperative diagnoses through external auditory canal biopsy and radiologic examination both failed. Even using a frozen section, an informative finding was not obtained because mostly granulation tissue was present along with associated squeezing artifacts. On permanent histologic examination, small cell nests between many ectatic small vessels and fibrotic stroma were seen, and those cells were positive for CD56, synaptophysin and chromogranin. Because JTPs are rare and have rather different histologic findings - higher vascularity, smaller and less uniform tumor cells than other paragangliomas - they are easy to misdiagnose. However, remembering those differences may help the physician avoid missing JTPs.

OBJECTIVETo analysis the effectiveness of preoperative digital subtraction angiography (DSA) on glomus jugularis tumors.

METHODSA retrospective study of 14 cases of glomus jugularis tumors which received preoperative DSA was carried out. Among them, 10 cases were accepted balloon occlusion test and selective embolization of supplied vessels.

RESULTSHypervascular changes was found in all 14 cases and compression of internal carotid artery was found in 5 cases. Ascending pharyngeal artery was the main supplied vessel. Balloon occlusion test was applied in 10 cases, 2 were intolerable and 8 were passed occlusion test. Ten cases were accepted embolizations and tumor blood supply was conspicuous decreased. Neurovascular complications did not occurred after DSA but postoperatively in 2 cases. Intraoperative bleeding was less in embolization patients than that of without embolization.

CONCLUSIONSPreoperative DSA association with balloon occlusion test and embolizations might be a safe option on surgery of glomus jugularis tumors.
