Intestinal vascular anomaly
From Chapter 8 – Gastrointestinal tract
Figure 8.74. Intestinal vascular anomaly in a 9 month old Labrador dog with vomiting and diarrhea. A and B: Transverse sonograms of one fluid filled colonic segment with a thickened, nodular-like wall made of intramural enlarged varices (arrows in A), as confirmed using color flow Doppler (in B). A large network of numerous anomalous small vessels was seen throughout the abdomen, especially in the mesentery and near the main portal vein. C: Transverse post-contrast CT image of the caudal abdomen showing the intramural colonic vessels (arrow). D: Reconstructed CT dorsal image illustrating the numerous anomalous enlarged and tortuous vessels supportive of portal hypertension and acquired portosystemic shunts. Note the intramural colonic vessels (arrows). The left side of the liver is nearly absent. Because of the guarded prognosis, the dog was euthanatized and the final diagnosis is arteriovenous malformation with marked arteriolar proliferation and hypertrophy, venous ectasia, lobular atrophy and fibrosis.

Atlas 2.0 is finally being printed!
What a long journey this was… and we’re happy our job is over… well nearly over. A few videos remain to be produced, but the good news is that the book is now in line to be printed and assembled before it is delivered to your door step ;-).
Making sure all new figures print out as expected was the tricky part, and this explains, at least in part, the long delay. Realistically, the book should be shipped to Europe and North America late August/early September, but the electronic version might be available in July. The format of this electronic version remains to be determined (eBook, Kindle, etc.), but regardless, it will allow access to our video collection (nearly 160!).
Stay put as we may have a couple of more giveaways for you ;-).
Testicular cryptorchidism in a dog
From Chapter 14 – Male Reproductive Tract
Figure 14.44. Testicular atrophy in an 1.5-year-old, right sided cryptorchid Shi Tzu. The right testicle is found in the abdominal cavity (A), adjacent to intestinal loops. It is small (1.4 cm long) while the left scrotal testicle (B, between cursors) is normal in size (2.2 cm long).

Fragmentation of the medial coronoid process
From Chapter 17 – Musculoskeletal System
Figure 17.23. Fragmentation of the medial coronoid process. A: Medial view of the elbow of a 12 month-old Labrador retriever dog produced with computed tomographic (CT) volume-rendering, on which the fragmentation of the medial coronoid process (FMCP) is well visualized. B: This longitudinal sonographic image was obtained with the probe placed medially on the joint, the marker oriented proximally. The joint capsule is distended and thickened (arrowhead) and a gap (arrow) is present at the distal aspect of the medial coronoid process (MCP). The humeral condyle (HC) is mildly irregular. C and D: Corresponding transverse CT (C) and sonographic (D) images in which a fissure (arrows) extends through the MCP. The joint capsule is distended (arrowhead). R, radial head. U, ulna.

Caudal vena cava thrombosis in two dogs
From Chapter 15 – Abdominal Cavity, Lymph Nodes & Great Vessels
Figure 15.26. Thrombosis of the caudal vena cava. A-B: In this dog with renal adenocarcinoma, there is an echogenic thrombus filling most of the venous (CVC) lumen in transverse (A) and longitudinal (B) planes. More caudally, it extends into the right renal vein that is markedly distorted by the malignant thrombus (T). K, right kidney; RA, right adrenal gland; Ao, aorta. C-E: In this other dog with adrenal adenocarcinoma, a thrombus (between cursors) is detected in the CVC. This thrombus is associated with contrast enhancement in dorsal SPGR MR image (D) and extends into an abnormal left adrenal (Ad). The transverse T2w MR image (E) shows the connection between the malignant thrombus (T) and the left adrenal (Ad) through the phrenicoabdominal vein, just ventral to the aorta (Ao).

Esophageal mass
From Chapter 4 – Thorax
Figure 4.27. Esophageal mass in a 14-year-old Welsh Corgi. A and B: Thoracic radiographs reveal a homogeneous, soft-tissue opacity (M, arrows) associated with the caudal mediastinum, in the caudal region of the esophagus (E), silhouetting with the diaphragm. The position of the ultrasound transducer is shown in B. C and D: Ultrasonographic and enhanced labeled images obtained with a ventral transhepatic approach (sagittal plane). At the level of the esophageal hiatus, the mass (M, arrows) is associated with the esophagus (E). Liver and stomach (S) are visible in the near field, and the lung-diaphragm interface (D) manifests as a curvilinear, strongly hyperechoic structure bordering the esophageal mass.
