“…It was, however, not performed in all of the cases, mainly because we, as described by other authors, were sometimes thinking of other diagnoses such as lymphadenitis, lymphoma, hemangioma, schwannoma, etc. As a 2.25%, complication rate has been reported with contrast angiography by retrograde femoral approach, other diagnostic methods (safer and possibly as reliable) including radionuclide angiography and dynamic computed tomography have been proposed [13][14][15]. Other noninvasive techniques such as static gray-scale ultrasound and magnetic resonance imaging have also been proposed as eventually helpful in diagnosis [16,17].…”

Carotid body tumors at high altitudes: Quito, Ecuador, 1987

et al. 1988

Carotid body tumors seem to be encountered more frequently in people living at high altitudes. Twenty lesions operated in 19 patients at a general hospital in Quito, Ecuador over a period of only 5 years are reported. All patients lived in the highlands of the Andean region. There was no operative mortality, and morbidity was comparable to other series. No malignant cases were found. A higher degree of suspicion to recognize tumors and to operate at an earlier stage of development and thereby diminish operative morbidity is recommended. The great reliability of contrast angiogram and the development of other noninvasive diagnostic techniques is stressed. A study of the incidence of this lesion in the entire country should be made in the future.

“…The radiological evaluation includes angiography, computed tomography and MRI examination. High resolution CT with contrast medium injection shows bone destruction very well and the intracranial extension of the tumour (Duncan et al, 1979;Shugar and Mafee, 1982). MRI examination demonstrates the characteristic pattern of the 'salt and pepper' appearance on T 2 W, images described by Olsen et al (1987) for tumours more than 2 cm in diameter.…”

MRI features in a malignant glomus jugulare tumour

et al. 1993

Magnetic resonance imaging (MRI) features in a case of malignant glomus jugulare tumour are reported. Chemodectomas are benign in 95 per cent of cases and malignant in five per cent. Only one case report of CT findings in this unusual CP angle tumour with pulmonary metastases has been cited in the literature.It is concluded that MRI can provide useful information about the nature of chemodectomas although it cannot dislinguish between benign and malignant tumours, except when regional lymph nodes are involved or when distant metastases exist.
