Higher values of the ultrasonographic parameters representing vascularity and perfusion of tumors in dogs were determined via PD ultrasonography after administration of contrast medium than via PD or CD ultrasonography without administration of contrast medium.

A nine-month-old golden retriever bitch was presented with exercise intolerance and recurrent nasal discharge. Based on clinical, radiographic and ultrasonographic examination, a diagnosis of rhinitis, situs inversus totalis and tricuspid valve insufficiency was established. The results of video- and electron microscopy studies of the respiratory epithelium were compatible with primary ciliary dyskinesia (PCD). However, no evidence of a primary ultrastructural defect of the cilia was found. The dog was euthanased because of the poor prognosis. At necropsy, a hydrocephalus internus and a subaortic stenosis were additionally diagnosed. PCD, in combination with situs inversus, has been previously reported in golden retrievers, but without a concomitant hydrocephalus internus. Furthermore, concomitant occurrence of internal cardiac malformation and PCD has not previously been reported in the dog.

Background: Boxers are predisposed to subaortic and pulmonic stenosis (SAS, PS). Screening of puppies may be useful in estimating the risk of their developing a defect that potentially compromises life expectancy or exercise tolerance.Hypothesis: Presence of SAS or PS in adult Boxers can be predicted by auscultation and Doppler echocardiography at 9-10 weeks of age.Animals: Eighty-five Boxer puppies examined at 9-10 weeks of age and at 12 months of age. Methods: Prospective, longitudinal observational study. Auscultation by stethoscope and continuous wave-Doppler echocardiography for peak velocities (V max ) in the aorta (Ao) and pulmonary artery (PA).Results: Intensity of heart murmurs in puppies correlated with V max Ao and V max PA in adults. V max Ao and V max PA in puppies correlated with V max Ao and V max PA in adults, respectively. From puppy to adult, V max Ao increased and V max PA remained unchanged. The negative predictive value for absent or only a soft ( II/VI) murmur in puppies being associated with V max Ao and PA 2.4 m/s as an adult was 90% and 3.5 m/s 100%. The negative predictive value of a V max 2.4 m/s as a puppy still being 2.4 m/s as an adult was 94% for Ao and 96% for PA, and of a V max 3.5 m/s, 99% for Ao and 100% for PA.Conclusions and Clinical Importance: Even though V max Ao increases during growth in Boxer puppies, indicating relative narrowing of the aorta, puppies with V max Ao 2.4 m/s do not usually progress to clinically have relevant SAS at 12 months of age.

SummaryThe clinical, ultrasonographic, arthrographic and histopathological aspects of a localized histiocytic sarcoma in the tendon sheath of the biceps brachii muscle in a Flat-Coated Retriever are described. An eight-year-old female Flat-Coated Retriever was referred for evaluation of chronic forelimb lameness. The orthopaedic examination revealed a painful shoulder joint. Ultrasonographic evaluation revealed distention of the tendon sheath of the biceps brachii muscle and the presence of multiple, hyperechoic structures in the distal portion of the sheath. The histological and immunohistochemical diagnosis of a biopsy taken during surgical exploration of the shoulder joint was histiocytic sarcoma. Palliative treatment with corticosteroids was administered but the dog was euthanized at the owner’s request four months following diagnosis due to progressing lameness. Post-mortem examination confirmed the diagnosis of histiocytic sarcoma without any evidence of metastases.
