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.

PURPOSE: To measure the magnetization transfer ratio(MTR) of intracranial tumors and to evaluate the difference of the character and the border of tumors on magnetization transfer image. MATERIALS AND METHODS: We prospectively reviewed magnetization transfer imaging(MTI) findings of intracranial tumors of 13 patients. 1.0T MRI machine was used. T1 weighted image(TRITE=700/14) and T1 weighted magnetization transfer image were obtained. The offset and bandwidth of magnetization transfer pulse were 1000 Hz and 250Hz, respectively. Postcontrast images were also obtained. MTR was measured at lesion area. RESULTS: The mean of normal MTR of white matter and gray matter in 7 normal volunteers were 37% and 29%, respectively. The MTR of each tumor was as follows;metastatic tumors(mean 16.3%), meningioma(mean 27.3%), oligodendroglioma(mean 20.2%), glomus jugulare tumor(mean 17.3%), gliomatosis cerebri(mean 27. 0%). The contrast of lesions were better at magnetization transfer image than at T1 weighted image. CONCLUSION: The MTR of the intracranial tumors is lower than normal tissue. Measurement of MTR at muirpie areas within the tumor can be useful for evaluation of indistinct border of the tumor.

Spinal accessory neuropathy is commonly caused by iatrogenic injury or secondary to trauma or infection. Nevertheless, the tumor related palsy is rare. We present a case of an 18-year-old male patient suffering from paralysis of his right trapezius and sternocleidomastoid muscle. An electrophysiologic diagnostic study confirmed the spinal accessory neuropathy of the proximal segment. In addition, magnetic resonance imaging showed the location of tumor on the jugular foramen. However, the type of the tumor was not confirmed through biopsy because the patient refused surgical procedure. Based on the study, it is hypothesized that the tumor located on the jugular foramen should be considered as a cause of the spinal accessory nerve of the proximal segment.

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.

Extra-adrenal paragangliomas are rare tumors of neural crest origin, usually arising from the carotid bodies, the glomus jugulare, or the retroperitoneum. And, though ten percents of cases are presented with malignancy, it`s prognosis is relatively good. In genitourinary area, there are a few reported cases of extra-adrenal paragangliomas of the urinary bladder and the spermatic cord. Herein, we report a case of paraganglioma arising in the scrotum, which is an extremely rare location.
