Fine Needle Aspirates and Ultrasound Guided Biopsy and Aspirates often provide a diagnosis without having to send a patient to surgery. Or help us learn more about the problem prior to surgery to maximize the success of a surgical procedure.

Dr. Treadwell assess samples the same day, allowing quick screening for infections, cancers and immune disease.


 Mast Cell Tumor


Small mass on the skin of a dog.  Fine Needle Aspirate of the mass showing round cells producing purple granules.  This is a Mast Cell Tumor.

Sampling this mass allowed a diagnosis made prior to surgical removal.  MCT must have a large amount of tissue removed to increase the chance of a cure - this is good to know before going to surgery.


The image on the left is an ultrasound image of a dog's thick section of intestine.  A Fine Needle Aspirate of the area shows large number of these round cells.  This is a cancer called lymphosarcoma.  LSA is not surgically correctable.  So this dog did not have to undergo an unnecessary surgery to obtain a diagnosis.



This sweet Cocker Spaniel's joints hurt - she could barely walk.   A joint tap of 2-3 joints showed large numbers of inflammatory cells (white blood cells).  She has a joint disease similar to Reheumatoid Arthritis in people.  The joint tap samples are the best way to determine if a disease like this is causing multiple joints to hurt and swell.   She has responded very well to treatment.
