“…Frequently reported in human pathology, CDH can be a part of a more complex congenital malformation involving other systems such as cardiovascular, genitourinary, neuronal and urogenital systems. In horses, CDH are rarely associated with concurrent skeletal malformation (as scoliosis, arthrogryposis and hypoplasia of the pelvic limb bones) [ 17 , 18 ] or malformation affecting the urogenital system (uterus unicornis, unilateral renal and ureteral agenesis) as recently reported by Silva et al [ 18 ]. Less frequently, CDH can be associated with cardiac defects.…”

BackgroundIn veterinary medicine congenital abnormalities of the diaphragm and pericardium are rare, idiopathic malformations, being reported mainly in dogs. This report documents an unusual case of developmental defects in a foal consisting of diaphragmatic hernia concurrent with pericardial aplasia.Case presentationFollowing a normal delivery, a full term, female Friesian stillborn foal with the placenta was presented for necropsy. External morphological examination indicated a normally developed foal. At necropsy, a large oval defect (approximately 20 × 15 cm in size) was observed in the left-dorsal side of the diaphragm (left lumbocostal triangle). This defect allowed the intestinal loops, spleen and partially the liver to translocate into the thorax. The loops of the left ascending colon, including the pelvic flexure and partially the small intestine covered the cranial and dorsal posterior parts of the heart due to the complete absence of the left pericardium. The remaining pericardium presented as a white, semi-transparent strip, partially covering the right side of the heart. The left lung and the main bronchus were severely hypoplastic to approximately one-fifth the size of their right homologue. The intermediate part of the liver, containing mainly the enlarged quadrate lobe was translocated in the thorax, severely enlarged and showed marked fibrosis. Histologically in the herniated lobes we diagnosed hepatic chronic passive congestion, telangiectasia and medial hypertrophy of blood vessels.ConclusionConcomitant malformation involving diaphragmatic hernia and pericardial aplasia in horses have not been previously reported. Moreover, this is the first case describing pericardial aplasia in horse.

“…When patellar abnormalities are suspected, lateromedial, caudoproximalcraniodistal oblique and craniodistal-cranioproximal (skyline) oblique radiographic views are commonly used to assess the stifle joint and position of the patella (O'meara & Lischer, 2009). Surgical repair of congenital patellar luxation carries a good prognosis in miniature horses and foals; however, most foals affected with congenital limb malformations such as ectopia, hypoplasia, aplasia, haemimelia or agenesis have a poor to grave prognosis, depending on the affected structures (Bertone & Aanes, 1984;Busschers 2009;DeBowes & Leipold, 1984;Finocchio & Guffy, 1970;Leipold & Macdonald, 1971;Modransky et al, 1987;Robbe et al, 2012;Silva et al, 2014;Van Pelt et al, 1971). In man, congenital patellar aplasia or hypoplasia is a rare autosomal dominant disorder, occurring in only a few families, and often does not cause major dysfunction (Sferopoulos, 2018).…”

A 2-day-old Cleveland Bay colt was referred to the Equine Emergency Service of the Farm Animal and Equine Veterinary Medical Center at North Carolina State University's College of Veterinary Medicine for evaluation of decreased nursing behaviour and right hindlimb lameness of 2 days' duration. When assisted to stand, the foal was unable to extend either hindlimb or bear weight on the hindlimbs, the right patella was luxated laterally and unable to be reduced, and the foal assumed a crouched position.Stifle radiographs revealed minimal, heterogeneous, ill-defined ossification of both patellae. Due to the severity of the musculoskeletal defects, humane euthanasia was elected. Post-mortem examination identified a congenital malformation of both patella bones with failure of ossification and cardiac changes suggestive of right atrioventricular valve dysplasia. Histology of the patellae showed no evidence of osteoid deposition or ossification. To our knowledge, bilateral congenital patellar aplasia has not been previously described in foals.
