Sciatic nerve sheath fibrosarcoma in a dog
From Chapter 18 – Spine and Nerves
Figure 18.24. Sciatic nerve sheath fibrosarcoma in a dog. A: Transverse sonographic image of a 2.15cm thick hypoechoic mass located dorsal to the acetabular bone (Ac) and femoral head (FH). B: Transverse post-contrast T1-weighted MR sequence with fat saturation, highlighting the contrast-enhancing mass (arrowheads). The adjacent muscles are atrophied and hyperintense. T, tail; P, pubis.

Echogenic peritoneal effusions in dogs and cats
From Chapter 15 – Abdominal Cavity, Lymph Nodes, and Great Vessels
Figure 15.6. Echogenic peritoneal effusions in dogs and cats. A: Longitudinal image of a dog with abdominal distension and pain. A large volume of particulate, echogenic, peritoneal effusion (*) is seen around the spleen (Sp). These features are suggestive of a cellular effusion, such as exudate or hemorrhage. A diagnosis of septic peritonitis was made based on fluid aspiration. B: In this cat with pancreatic adenocarcinoma and carcinomatosis, there is marked peritoneal effusion (*) that presents hyperechoic speckles. A hypoechoic nodule (arrow) is detected in the omentum C: Chylous effusion (*) is typically of moderate to high echogenicity as in this dog. BL, bladder. D: Longitudinal image of the caudal abdomen of a cat diagnosed with multifocal biliary carcinomas. Floating, echogenic structures (*), not attached to any structure and consistent with blood clots, were identified cranial to the bladder (BL).

[VIDEO] Image Formation and other principles
From the video collection of Chapter 1 – Practical Physics and Artifacts, here is the first tutorial on the basics of ultrasound image formation and other physical principles that influence image quality. Got get your popcorn and select 720pHD under parameters (once the clip starts) for an optimised experience. 🙂
Transitional cell carcinoma (TCC) in dogs
From Chapter 11 – Bladder and Urethra 
Figure 11.16. Transitional cell carcinoma (TCC) in dogs. A: Longitudinal sonogram of an extensive TCC affecting the ventral and dorsal bladder wall, in a 10 year old Lhapsa Apso. B: In the same dog as A. the TCC extends caudally into the bladder neck and urethra (U). C: A cauliflower shaped nodule arising from the craniodorsal wall was found incidentally in a dog presented for urinary obstruction secondary to a urethral calculus. It was confirmed as papillary non infiltrating TCC after surgical removal. D: Longitudinal sonogram of a broad-based hyperechoic mass associated with the craniodorsal bladder wall, consistent with transitional cell carcinoma. E: Longitudinal sonogram in another dog without urinary clinical signs in which focal irregular thickening of the dorsal bladder wall was detected incidentally. Color Doppler signal (arrow) confirmed that this lesion was attached to the bladder wall, as opposed to a blood clot. F: Two separate transitional cell carcinoma masses (M1 and M2) in another dog with mineralization causing acoustic shadowing (*). The arrowheads delineate the apical bladder wall.

Color tabs, an easier way to find your chapter
With nearly 600 pages of text and figures, it will be easier this time to find the chapter you’re looking for. 🙂
Intestinal mucosal hyperechoic striations
From Chapter 8 – Gastrointestinal Tract
Figure 8.31. Mucosal hyperechoic striations. Longitudinal (A) and transverse (B) sonograms of thickened jejunal segments with hyperechoic linear striations within the mucosal layer of a 5 year old French Bulldog. The striations represent dilated lacteals. This dog had a long history of inflammatory bowel disease. Peritoneal effusion is present (*). C and D: Similar but more severe findings are present in this 9 year old Jack Russell terrier presented with protein losing enteropathy. Note the thickened and hyperechoic adjacent fat (F), often present in these cases.

Snowfall in a bladder
It’s Friday. We may work hard as veterinarians but it doesn’t mean we can’t have fun and enjoy what we see. For those of you that miss winter – or have never seen it – feel free to get rid of your fake fireplace video and use this instead. 🙂 (this animation may take a little time to show up depending on your connection).
