Summary
This study clarifies computed tomography (CT) features of canine prostatic carcinoma (PC). Key findings include prostatic heterogeneity, capsular distortion, and lymph node enlargement, aiding diagnosis.
Area of Science:
- Veterinary Radiology
- Canine Oncology
Background:
- Canine prostatic carcinoma (PC) diagnosis is challenging due to poorly defined computed tomography (CT) features.
- Accurate staging requires understanding prostatic, regional, and distant findings.
Purpose of the Study:
- To assess and define the characteristic CT findings of canine prostatic carcinoma.
- To provide guidance for diagnosing PC in dogs using CT imaging.
Main Methods:
- Multicenter retrospective case series involving 30 dogs with confirmed PC.
- Analysis of prostatic, regional lymph node, and distant metastatic findings on CT scans.
Main Results:
- Consistent prostatic CT features: postcontrast heterogeneity, capsular distortion, urethral involvement, and mineralization.
- Common extraprostatic findings: medial and internal iliac lymphadenopathy, periprostatic fat changes.
- Less frequent findings: lymph node mineralization, bladder/ductus deferens invasion, hypertrophic osteopathy, and vertebral metastases.
Conclusions:
- CT imaging reveals consistent patterns in canine prostatic carcinoma.
- These findings improve the characterization and staging of canine PC on CT.
