[Value of radiological examination in patients with pheochromocytoma. Results in four cases (author's transl)].

The authors report 4 cases of pheochromocytoma and analyse the interest of the different x ray examinations. The authors show the interest of angiography, particularly selective angiography, for small tumors, ectopic and multiple abdominal localisations, and metastases. The benign or malignant nature of the tumor, in the absence of metastases, is difficult to assess by x ray examinations alone.
