Plain-English summary
A dog with a soft tissue tumor was examined using ultrasound to better understand its characteristics. The ultrasound helped identify features like the tumor's size, shape, and blood flow, which can provide clues about the type of tumor, such as mast cell tumors or soft tissue sarcomas. While the ultrasound showed promise in distinguishing between different types of tumors, it cannot replace the need for a biopsy to confirm the diagnosis. This study highlights the potential of ultrasound as a helpful tool in veterinary diagnostics.

Abstract
OBJECTIVE: To identify and describe the ultrasonographic features of soft tissue tumours in dogs. PROCEDURE: Superficial soft tissue tumours of various histological types, including mast cell tumours (MCTs) and soft tissue sarcomas (STSs), were evaluated. Ultrasound was used to visualise internal characteristics of the tumour, including vascularity. Tumours were categorised according to size, shape, margin definition, tissue plane mobility, echogenicity, echotexture, acoustic shadowing or enhancement and vessel distribution. Objective measurements of intratumoural blood flow included velocities and maximal perfused cross-sectional area (fractional area). Logistic regression models incorporating a variety of data were used in an attempt to predict the histopathological type of tumours. RESULTS: The logistic regression model defined by the parameters echotexture, margin definition and presence of subcapsular vessels was highly predictive of MCTs (> 73%; P = 0.024). Several other trends, including a larger size for STSs and less vascularity for both MCTs and STSs, were observed, but did not reach statistical significance. CONCLUSION: This preliminary study has shown the potential diagnostic value of ultrasound in differentiating soft tissue tumours. However, at present, ultrasound cannot replace biopsy and histopathological evaluation for tumour diagnosis.
