Feeding artery of a recurrent pheochromocytoma from the left internal thoracic artery demonstrated by multislice computed tomography

A 53-year-old female presented to our hospital because of an abnormal shadow on chest X-ray. She had previously undergone surgical removal of a pheochromocytoma. Enhanced multislice CT was performed and three-dimensional volume rendered images revealed two tumors in the thorax and neck, suggesting pheochromocytoma. There was an aberrant artery originating from the left internal thoracic artery (ITA) leading to the tumor, which we identified as the feeding artery of the pheochromocytoma. We planned to eliminate the tumors surgically, and based on the multislice CT findings, we also planned to simultaneously eliminate the feeding artery from the left ITA.
