“…This case also had evidence of a large‐volume pleural effusion. Considering the low attenuation (4 HU) on CT and the serosanguinous nature, it likely represented a transudate 34 35. Pleural effusion has been previously reported in two dogs with LLT 1 13.…”

“…Total bilirubin was within normal limits (5.0 μmol/l; RI: <5). A coagulation profile revealed mildly prolonged prothrombin time (PT) of 15 seconds (RI: 7-12), but normal activated partial thromboplastin time of 21.6 seconds (RI: [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Fibrinogen was reduced (0.77 g/l; RI: 1-5) and D-dimers were severely increased (3.518 µg/ml; RI: <0.25).…”

A 9.5-year-old, neutered male, large crossbreed dog presented with unspecific clinical signs of lethargy, vomiting, anorexia and polydipsia. CT and blood analyses were consistent with liver lobe torsion with secondary disseminated intravascular coagulation causing renal and myocardial infarction and pulmonary thromboembolism. To the authors’ knowledge, this is the first case of a suspected liver lobe torsion displaying a ‘whirl sign’ and also the first CT description of a presumed myocardial infarction in a dog.

“…In comparison to radiography, computed tomography would yield a more detailed assessment of underlying parenchymal and pleural abnormalities, avoid the superimposition of images, provide details with regard to severity and provide an opportunity for the assessment of mediastinal, sternal and tracheobronchial lymph node enlargement [ 9 ]. A previous study reported that computed tomographic attenuation values can be a possible predictor of the type of pleural fluid [ 33 , 34 ]. Nevertheless, this method might not be feasible and can be inconsistent in sensitivity due to the technological and technical difference of the respective computed tomography scanner used.…”

This retrospective study aimed to determine the etiological, clinicopathological, and radiographic features and outcome of feline pyothorax cases. Medical records from twenty-eight cats with pyothorax aged from 4 months to 10 years (median 10 months) diagnosed between 2013 and 2020 were reviewed. Dyspnoea (75.0%), abnormal lung sounds (75.0%) and open-mouth breathing (64.3%) were the predominant respiratory signs. Leucocytosis (61.5%), particularly monocytosis (68.0%), and hyperglobulinaemia (65.4%) were among the most prominent findings in blood analysis. Bilateral pleural effusion was found in 67.9% of the thoracic radiographs. A total of 47.4% of the cytological samples revealed the presence of bacteria, while all had positive bacterial growth. Pasteurella multocida, E. coli, Streptococcus spp., and Staphylococcus spp. were the predominant aerobic bacteria isolated from pleural effusion samples. A chest tube was placed in 64.3% of the cats and 66.7% of cats with chest tubes survived. In total, 46.4% of cats with pyothorax recovered. Amoxicillin–clavulanate was the antimicrobial of choice against aerobic bacteria found in this study and should be given in combination with antimicrobials that cover anaerobic bacteria. Chest tube placement is crucial for treatment success. Cytological results and bacterial culture may not be consistent; thus, bacterial culture should be performed for every case.

Objective This retrospective case series describes the clinical presentation and CT findings of dogs with presumed mediastinal haemorrhage with no apparent identifiable underlying cause. Materials and Methods Medical records were searched for dogs with presumed or suspected mediastinal haemorrhage of non‐thymic origin. For all dogs, data on signalment, history, physical examination, treatment and outcome were collected by reviewing the medical records. Follow‐up information was collected by telephone interviews with the owners and/or their primary‐care veterinarians. Results Four dogs were included. All survived to discharge with apparent resolution of the mediastinal haemorrhage (based on repeat imaging and/or clinical signs) with supportive treatment alone. Follow‐up information was available from 2 months to 5 years following discharge, and none of the patients showed a recurrence of clinical signs during this period. Clinical Significance This case series highlights that presumed haemorrhage into the mediastinum can occur in dogs without an obviously identifiable cause and, whilst rare, should be considered as a cause of dorsal mediastinal masses and may be successfully managed with supportive care alone.
