I have to confess that this dog caught me out initially. A 12 m.o. Springer Spaniel; relatively well in herself but presenting with abdominal distention due to progressive ascites (of the modified transudate variety). No loud murmur. This is the liver: That’s not normal. The parenchyma is heterogeneous: specifically, the centres … Continue reading
Just a little image of interest…to show how closely the pancreas is associated with the transverse and descending left colon in the dog. And how the colon is enveloped within the resulting swamp of inflamed fat when the pancreas is poorly. And a still image of the very inflamed-looking ileo-caeco-colic junction from the … Continue reading
Pulmonary oedema in cats and dogs is typically characterised by increased ‘B lines’ (also known as ultrasound lung rockets or comet-tail artefacts). This is a feature of oedema in the broadest sense and is not specific to aetiology. Differential diagnosis of this phenomenon includes trauma, electrocution, acute respiratory distress syndrome/acute lung injury, overhydration, asthma, near-downing … Continue reading
This patient is a five-month-old DSH with a history of ill-thrift and presumed hepatic encephalopathy (episodic hypersalivation, ataxia, blindness, seizures). Interestingly, her fasting bile acids were unremarkable. However, on abdominal ultrasonography there are all kinds of shenanigans: First off, the left side of the liver contains a bizarre, aneurysmal dilation of the vasculature which communicates … Continue reading
Gastric and duodenal ulceration is probably relatively common in dogs: usually secondary to NSAID and/or glucocorticoid treatment, liver disease, hypoadrenocorticism, mast cell tumours or gastrinoma. However, perforation and subsequent septic peritonitis is less frequent. In fact there are few published cases. Hinton L. E., McLoughlin M. A., Johnson S. E. & Weisbrode S. E. … Continue reading
Not rocket science but I’ve not seen a published image of this. Transverse view of the distal part of the gracilis muscle in a Greyhound with recurrent lameness, bruising and swelling on the inner aspect of the proximal tibia. In comparison to the unaffected side: There is convincing disruption of the … Continue reading
FIP is frequently included in differential diagnosis lists for feline pancreatitis. However, there seems to be a lack of specific case descriptions other than in post-mortem histopathological surveys. There’s only one paper that I’m aware of looking at sonographic features of FIP: Abdominal ultrasonographic findings associated with feline infectious peritonitis: a retrospective review of … Continue reading
Just a nice image from today: a pup with 2 month history of persistent haematochezia and diarrhoea. Unresponsive to dietary manipulations, beta-lactams or antihelminthics. …but faecal microscopy positive for Isospora. Normally I have a healthy scepticism for the significance of faecal ‘pathogens’ but in this case it does seem a plausible explanation for … Continue reading
This is just a snippet but maybe worth including because I’m not aware of any published images of the pancreas in cats with EPI. For example, there is no mention of imaging in this recent case series: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5115185/ J Vet Intern Med. 2016 Nov-Dec; 30(6): 1790–1797. Feline Exocrine Pancreatic Insufficiency: A Retrospective Study of 150 … Continue reading
This is something I’ve long been interested in. A friend of mine, half joking I think, suggested to me that our aim should be to suppress the development of other budding sonographers in the practices which we visit. I tried to defend myself that this is not the case. I strongly believe it’s a win-win. … Continue reading
