Computed tomography of juxtacardiac pheochromocytoma.

The diagnosis of juxtacardiac pheochromocytoma was made with the help of three-dimensional computed tomography, angiography, and radionuclide scintigraphy, and was proved at surgery. If findings on adrenal computed tomography are normal and the clinical and laboratory findings support the diagnosis of pheochromocytoma, the patient should be further investigated by computed tomography or radionuclide-guided computed tomography and angiography to determine the extraadrenal location of this tumor. If the abnormal area is in the mediastinum, it is essential to do either direct coronal computed tomography imaging of the suggestive area or to obtain coronal and sagittal reconstruction images to investigate the relationship of the lesion to the great vessels and cardiac chambers.
