Dog With Persistent Nasal Bleeding — Veterinary Endoscopy Revealed a Hidden Nasal Tumor

Chronic nasal bleeding in dogs is often mistaken for simple rhinitis or infection. However, persistent unilateral nosebleeds may indicate serious underlying diseases, including nasal tumors, foreign bodies, fungal infections, or severe inflammatory lesions.

This case demonstrates how veterinary endoscopy enabled direct visualization of a hidden nasal lesion that could not be accurately evaluated through routine examination alone.

Case Background

• Species: Dog
• Gender: Male

Chief Complaint

• Recurrent unilateral nasal bleeding
• Frequent sneezing
• Mild breathing difficulty
• Reduced appetite

The symptoms had persisted for several weeks despite routine symptomatic treatment.

Clinical Challenge

Nasal diseases are difficult to diagnose because:

• ▪️The nasal cavity is narrow and deep
• ▪️Routine examination provides limited visibility
• ▪️X-ray imaging may miss early lesions
• ▪️Blind treatment often delays accurate diagnosis

Possible differential diagnoses included:

• ▪️Nasal foreign body
• ▪️Severe rhinitis
• ▪️Fungal infection
• ▪️Nasal polyp
• ▪️Nasal tumor

▪️Direct visualization was required for accurate diagnosis.

Endoscopic Nasal Examination

The veterinary team performed rhinoscopy using the JeetVet RAE-109 portable veterinary endoscope.

• ▪️General anesthesia administered
• ▪️Endoscope inserted through the nasal cavity
• ▪️Continuous insufflation for improved visualization
• ▪️Sequential examination of the nasal passage
• ▪️Identification of abnormal proliferative tissue

Key Findings

• Irregular proliferative tissue observed inside the nasal cavity
• Localized bleeding and mucosal inflammation
• Partial airway obstruction

The lesion was highly suspicious for a nasal tumor.

Biopsy samples were collected under direct visualization for pathological analysis.

Why Veterinary Endoscopy Was Critical

1. Direct Visualization

The endoscope enabled clear observation of:

• Tumor margins
• Bleeding points
• Mucosal condition

This significantly improved diagnostic accuracy.

2. Minimally Invasive Diagnosis

Traditional exploratory surgery was avoided.

• Reduced patient trauma
• Lower complication risk
• Faster postoperative recovery

3. Accurate Biopsy Collection

Under endoscopic guidance, tissue samples were collected precisely from abnormal regions, improving pathology reliability.

Veterinary Rhinoscopy vs Traditional Examination

Comparison	Veterinary Endoscopy	Traditional Examination
Visualization	Direct high-definition visualization	Limited external observation
Diagnostic Accuracy	High	Often inconclusive
Biopsy Capability	Precise targeted biopsy	Difficult or blind sampling
Trauma	Minimally invasive	May require surgical exploration
Recovery	Fast	Longer recovery time

How JeetVet Endoscope Helped

The JeetVet RAE-109 portable veterinary endoscope provided several advantages during the procedure:

• ▪️Slim insertion tube for narrow nasal passages
• ▪️High-definition imaging for lesion identification
• ▪️Flexible maneuverability inside complex anatomy
• ▪️Portable connection to phone and computer
• ▪️Working channel for biopsy and treatment instruments

Especially suitable for:

• ▪️Rhinoscopy
• ▪️Nasal foreign body removal
• ▪️Biopsy procedures
• ▪️Upper respiratory examination

Treatment Outcome

• Nasal bleeding significantly improved
• Breathing became more stable
• Earlier treatment planning became possible
• Recovery monitoring was continued

Early endoscopic diagnosis allowed faster clinical intervention and improved prognosis.

Clinical Value of Veterinary Endoscopy

Compared with traditional methods, veterinary endoscopy offers:

• ▪️Earlier diagnosis
• ▪️More accurate lesion localization
• ▪️Better treatment planning
• ▪️Reduced patient trauma

Minimally invasive respiratory endoscopy significantly improves veterinary diagnostic capability and clinical efficiency.

Conclusion

Persistent nasal bleeding in dogs should never be ignored.

Veterinary endoscopy provides a safe and highly effective method for diagnosing hidden nasal diseases, enabling:

• ▪️Accurate visualization
• ▪️Precise biopsy collection
• ▪️Minimally invasive intervention
• ▪️Faster clinical decision-making

Modern veterinary rhinoscopy is becoming an essential tool for advanced respiratory diagnostics in companion animals.
