    Abstract:
    Localization tests including TC-scans, scintigraphy with 131I-radiolabelled metaiodobenzylguanidine and ultrasound have been performed in 68 patients with diagnosed pheochromocytoma. Diagnosis was based on clinical symptoms and increased catecholamines and/or their metabolites excretion with the urine. Proper diagnosis with CT-scans was 97%, scintigraphy--92%, and ultrasound--93%; false negative results in scintigraphy amounted to 8% (3 patients) and 5% (3 patients) in case of ultrasound. CT-scans were free of such errors. False positive diagnosis was made in 2 (3%) patients with CT-scans and in 1 (2%) patient tested with ultrasound. These results suggest that pheochromocytoma may be precisely localized with non-invasive techniques, especially CT-scans.
