Summary
This study assessed a new stereotactic CT-guided brain biopsy (SCTGBB) device for diagnosing brain lesions in dogs. The SCTGBB device proved accurate, enabling diagnoses in most cases with manageable complications.
Area of Science:
- Veterinary Neurology
- Neurosurgery
- Diagnostic Imaging
Background:
- Brain lesions in dogs present diagnostic challenges.
- Accurate tissue sampling is crucial for definitive diagnosis and treatment planning.
Purpose of the Study:
- To evaluate the accuracy and safety of a novel stereotactic CT-guided brain biopsy (SCTGBB) device.
- To determine the diagnostic yield of SCTGBB in canine brain lesions.
Main Methods:
- The study involved 23 client-owned dogs with suspected brain lesions.
- Stereotactic CT-guided brain biopsy (SCTGBB) was performed.
- Cytological and histological evaluations were used for diagnosis.
Main Results:
- Biopsy of the target lesion was successful in 95% of cases.
- A diagnosis was achieved in 16 dogs via cytology and 21 dogs via histology.
- Complications occurred in six dogs, including two fatalities with brainstem tumors.
Conclusions:
- Stereotactic CT-guided brain biopsy (SCTGBB) is an accurate and effective method for diagnosing brain lesions in dogs.
- The diagnostic yield is high, supporting its use in veterinary neuro-oncology.
