  • Abstract
  • Look Inside

A 73-year-old male had received, 35 years ago, enucleation, tumor resection and radiation for chondrosar-coma in his right orbit. He was referred to us for unstable prosthesis. Biopsy of the orbital content showed class V car-tilate matrix. Computerized tomography (CT) showed a moderate-constrast lesion including multiple high-contrast spots in the right orbit. Findings were present suggestive of bone erosion due to invasion of the tumor. Magnetic reso-nance imaging (MRI) showed low intensity on T1-weighted images and mixture of high and low intensity on T2-weighted images. The whole orbital content showed enhancement by MRI with Gd-DTPA. The findings did not rule out recurrence of chondrosarcoma. Resection of the tumor led to the histopathological diagnosis of benign pleomorphic adenoma. There has been no recurrence during 28 months of follow up.
