Abstract:
A 13-year-old woman with a history of left malignant carotid body paraganglioma status postsurgical resection underwent 123I-MIBG scan for staging. The images demonstrated no definite evidence of MIBG-avid disease. However, there was asymmetric activity in the region of the brain with relatively less activity on the left compared with the contralateral right side on the head images, which was related to prior infarct revealed from the patient's history. This asymmetric MIBG activity persisted 8 years later.
