ABSTRACT
BACKGROUND:
Only ten cases of the rare occurrence of a malignant peripheral nerve-sheath tumor (MPNST) arising in a ganglioneuroma either de novo or at a site of previous irradiation have been reported. PATIENTS ANDMETHODS:
We present two children who at the age of 19 months and 6 months were diagnosed with a cervicothoracic ganglioneuroblastoma and a retroperitoneal neuroblastoma, respectively. They both received radiation therapy as part of the treatment of their disease.RESULTS:
Following a 12-year interval, MPNST arose inside a benign ganglioneuroma in both patients. We illustrate the imaging findings in these two cases and review the cases reported in the literature to increase awareness of this association among radiologists.
