Ultrasonographic and colour Doppler features of intrapancreatic splenic tissue in a cat

Abstract

Case summary A 2-year-old female neutered domestic longhair cat was referred for a 3-day history of lethargy and anorexia. Physical examination documented abdominal distension and pain, which, alongside marked electrolyte imbalances on blood biochemistry, was highly suspicious for a gastrointestinal obstruction. This was confirmed on diagnostic imaging, with abdominal ultrasonography also identifying an incidental, well-defined small lobular hypoechoic nodule adjacent to the tail of the spleen, with high vascularity on Doppler interrogation. This was identified as a focal nodule at the tip of the left limb of the pancreas at surgery, and resected via partial pancreatectomy. Histopathological examination confirmed intrapancreatic splenic tissue. Relevance and novel information This case report presents the first available ultrasonographic description and images of intrapancreatic splenic tissue in a cat. It is thought to be a benign lesion of low clinical significance and therefore defining its imaging characteristics may allow for improvement in diagnostic suspicion without resorting to excisional surgery.

Intrapancreatic accessory spleens in African swine fever infection of wild boar (Sus scrofa)

“…The intrapancreatic accessory spleen (IPAS) has being identified as a common congenital splenic anomaly in humans, however, studies in veterinary medicine are scarce (7)(8)(9). Most of these studies do not establish the cause behind the presence of IPAS but describe its accidental finding and misdiagnosis due to its high similarity with other types of lesions (20).…”

“…Thus CD3 (T cells) and CD79 (B cells) were used to characterize the phenotype lymphocytes. To detect the presence of ASFV, a semiquantitative assessment of cells immunolabeled for ASF viral antigen (protein VP72-18BG3) was performed and were evaluated as follows: immunolabeled mononuclear cells were counted in 5 adjacent, non-overlapping fields Scheme of the study design including the three groups (LVI-HVI, HVI and control group), from prime inoculation to the end of the experiment (7,11,15,20,27 and 54 days post-infection). 3 Results…”

“…The description of intrapancreatic accessory spleen (IPAS) is a frequent phenomenon in humans that poses no clinical significance (4,6). However, the occurrence of IPASs in animals is poorly documented in the literature, with only a few cases described in dogs and cats (5,7,8), domestic pigs (9,10), rabbits (3,(11)(12)(13), marine mammals (14)(15)(16)(17) and non-human primates (18).…”
