Ectopic splenic nodules in the olive baboon (Papio cynocephalus anubis)

Abstract

Post-mortem evaluation of a female sub-adult olive baboon (Papio cynocephalus anubis) revealed a case of ectopic spleen anomaly. Three spherical masses characterized the spleen anomaly. The splenic nodules were located on the left upper quadrant of the stomach, at the distal end of the pancreas. The anterior nodule measures 1.2 cm, the middle nodule 1.9 cm and the posterior nodule 1.3 cm in diameter. Normal spleen was not observed in this case. All the three ectopic splenic nodules showed normal histological architecture. A case of ectopic splenic nodules in baboon is important in that the spleen malformation can readily be mistaken for a pathological process.

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

“…Intrapancreatic splenic tissue (IPST) is sporadically reported in veterinary species, including dogs, 1 cats, 1,2 rabbits, 3,4 pigs, 5,6 cetaceans 7 and non-human primates. 8,9 IPST can have two possible origins, indistinguishable on histopathology: splenosis, which consists in autotransplantation of splenic tissue in a patient (ie, following trauma); or accessory spleen, which consists of aberrantly located splenic masses of congenital origin. 10…”

Intrapancreatic accessory spleen in a harbor porpoise (<i>Phocoena phocoena</i>)

“…Intrapancreatic accessory spleens (IPAS) are typically incidental findings during surgery for other conditions but can pose a clinical challenge via multiple imaging techniques, mimicking hypervascular and neuroendocrine tumours [ 17 ]. While IPAS are not uncommon in humans [ 15 ], they are seldom described in the veterinary literature, including only a few cases in nonhuman primates [ 8 , 12 ], pigs [ 10 , 16 ], rabbits [ 1 , 6 ], and dogs and cats [ 13 ].…”
