The Clinical Application of Dynamic Contrast-Enhanced MRI in Canine Masses of Mesenchymal and Epithelial Origin: A Preliminary Case Series.

Vet Sci

November 2024

Department of Veterinary Medical Imaging, College of Veterinary Medicine, Konkuk University, Seoul 05029, Republic of Korea.

Evaluating masses of mesenchymal and epithelial origin accurately using computed tomography (CT) has several limitations in dogs. This study aimed to present dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters to aid in improving the diagnostic accuracy for masses of mesenchymal and epithelial origin in veterinary medicine. Four dogs diagnosed with benign and malignant soft tissue sarcoma (STS), cholesteatoma, or squamous cell carcinoma underwent CT, conventional MRI, and DCE-MRI.

Ciliary body myxoid epithelioid sarcoma in a cat: a case report.

BMC Vet Res

October 2024

Western College of Veterinary Medicine, University of Saskatchewan, Saskatoon, SK, Canada.

Article Synopsis
  • A rare myxoid intraocular neoplasm originating from the ciliary body was discovered in a 14-year-old female cat, characterized by a bubble-shaped mass that led to secondary glaucoma and necessitated enucleation.
  • Histological and immunohistochemical analysis revealed a multinodular hypocellular neoplasm with strong cytokeratin and vimentin reactivity, suggesting an epithelioid myxosarcoma diagnosis.
  • The case highlights the need to consider epithelioid myxosarcoma in differential diagnoses for feline intraocular tumors and stresses the importance of early surgical intervention to prevent further complications.
