Magnetic resonance imaging of primary orbital Ewing's sarcoma

Pediatr Neurosurg. Jul-Aug 2005;41(4):192-6. doi: 10.1159/000086560.


The authors describe the MRI findings of a primary orbital Ewing's sarcoma in a 5-year-old boy, who underwent an extensive tumour surgery as these findings were mistaken for more chemoresistant sarcomas such as rhabdomyosarcoma. This case illustrates the fact that MR findings of primary orbital Ewing's sarcoma may be different from those of Ewing's sarcoma present elsewhere in the body. An accurate preoperative diagnosis may therefore result in a more conservative approach and prove extremely useful in such tumours.
