AI Article Synopsis

  • A 10-year-old Labrador Retriever with a history of flank tumors presented with a painful left eye, leading to diagnosis of secondary glaucoma and blindness.
  • Diagnostic surgery revealed that the eye problem was due to a metastatic spindle cell sarcoma, originating from the previously treated flank mass.
  • The dog's condition worsened rapidly post-surgery, resulting in euthanasia just a month later; this case is the first to document such intraocular metastasis in veterinary medicine.

Article Abstract

A 10-year-old Labrador Retriever who had been undergoing therapy for a recurrent hemangiopericytoma of the right flank presented to the Kansas State University Ophthalmology service for evaluation of a painful left eye. Examination revealed secondary glaucoma and irreversible blindness of the affected eye and multifocal chorioretinal lesions in the fellow eye. Therapeutic and diagnostic enucleation of the left eye was performed and histopathologic examination demonstrated the presence of a presumed metastatic spindle cell sarcoma. Further immunohistochemical staining confirmed the intraocular neoplasia to be metastatic spread from the previously removed flank mass. Rapid progression in size and number of chorioretinal lesions in the right eye was noted in the post-operative period until the patient was euthanized one month after surgery. This case report is the first to document intraocular metastasis of hemangiopericytoma in a veterinary patient.
