[Computed tomography and scintigraphy in malignant pheochromocytoma].

Two patients with malignant metastasising phaeochromocytomas are described. Special attention is paid to the findings on computed tomography and scintigraphy with meta-I-benzylguanidine. The scintigraphic findings are not uniform. A review of the literature has shown that the sensitivity of scintigraphy is less for malignant phaeochromocytomas than it is for benign tumours.
