Abstract

Abstract : Lymph nodal cyst‐like lesions are occasionally identified during abdominal ultrasound in dogs. However, a study evaluating their prevalence and clinical significance is lacking. The aim of this observational cross‐sectional study was to evaluate prevalence, most common location and concurrent diseases of cyst‐like lymph nodes detected during abdominal ultrasound. Affected lymph nodes, patient signalment and concurrent diseases of dogs with cyst‐like lymph nodal lesions having undergone abdominal ultrasound over a one‐year period were recorded. Twenty‐three affected lymph nodes were observed in 17/553 dogs (prevalence=3 per cent). The most commonly affected was the lumbar lymphocenter (7/23), followed by the coeliac (6/23), the cranial mesenteric (5/23) and the iliosacral (5/23). Twenty‐three concurrent diseases were diagnosed in 17 dogs, among which 16/23 were non‐neoplastic (70 per cent). The most common concurrent disease was renal insufficiency (8/23), followed by neoplasia (7/23), gastroenteropathy (3/23), benign prostatic disease (2/23), pancreatitis (1/23), peritonitis (1/23) and neurological disease (1/23). No statistical correlation existed between cyst‐like lymph nodal lesion and a specific neoplastic or non‐neoplastic disease. In conclusion, in the present study, cyst‐like lymph nodal lesions have a low prevalence, involve different lymphocenters and were found in dogs affected by different diseases, including both non‐neoplastic and neoplastic aetiologies.
