Abstract:
Magnetic resonance (MR) was conducted for an 8-year-old, intact male Spitz with sneezing, serous discharge and epistaxis from the left nasal cavity. MR imaging showed a nasal cavity-occupied mass of iso-intensity on T1WI , high-intensity on T2WI and markedly enhanced on contrast-enhanced T1WI at parts of rostal to medial ocular angle in the left cavity. After Surgery and intraoperative radiation, the mass was diagnosed intranasal hemangiosarcoma by histopathology. Although the dog showed the finding, which suggested recurrence after the treatment ending, about 30 months later, it maintained good conditions without evidence of metastasis.
Insights
This study details a canine nasal hemangiosarcoma case diagnosed via magnetic resonance imaging (MRI). The dog, treated with surgery and radiation, showed no metastasis 30 months post-treatment.
Area of Science:
- Veterinary Medicine
- Canine Oncology
- Diagnostic Imaging
Background:
- Nasal tumors in dogs can present with varied clinical signs.
- Accurate diagnosis is crucial for effective treatment planning.
- Magnetic resonance imaging (MRI) is a key diagnostic tool for nasal cavity pathologies.
Observation:
- An 8-year-old male Spitz presented with sneezing, serous discharge, and epistaxis.
- MRI revealed a left nasal cavity mass with specific signal characteristics on T1WI, T2WI, and contrast-enhanced T1WI.
- The mass was located rostral to the medial ocular angle.
Findings:
- Histopathology confirmed the mass as intranasal hemangiosarcoma.
- The dog underwent surgery and intraoperative radiation therapy.
- Post-treatment, the dog remained in good condition with no signs of metastasis at 30 months, despite potential recurrence indicators.
Implications:
- This case highlights the utility of MRI in diagnosing canine nasal hemangiosarcoma.
- It demonstrates a positive long-term outcome following multimodal treatment.
- Early detection and intervention are critical for managing canine nasal tumors.
