A 2-year old female domestic shorthair cat was referred with intermittent vomiting. Laboratory analyses revealed only an elevated alanine aminotransferase activity. Plain thoracic radiographs showed a right-sided transdiaphragm protrusion of a liver lobe into the thoracic cavity. On abdominal ultrasound the diaphragm and liver parenchyma also presented a bulge towards the thoracic cavity. By cranial median laparotomy herniation of the quadrate liver lobe through the right aspect of the diaphragm into the thoracic cavity was confirmed. The protruding quadrate liver lobe was covered by intact parietal peritoneum. Following relocation of the liver lobe the defect was closed. Postoperatively the intermittent vomiting stopped. The purpose of this case report was to present plain radiography and abdominal ultrasonography as effective tools in the diagnosis of this rare and usually asymptomatic true herniation case along with its operative treatment.

The subject of hip dysplasia in dogs is still current and preoccupies both animal owners and veterinarians. Major factors affecting the development of the disorder are hip laxity and incongruent joints. Many studies on etiology, pathogenesis, and early diagnosis have been performed to reduce prevalence and select healthy dogs for breeding. The purpose of the present study was to investigate a possible relationship between dysplasia and femoral head area (FHA), femoral coverage by the acetabulum (CFH) and cranio-caudal distance of the dorsal acetabular rim (CrCdAR). Radiographs of a total of 264 skeletally mature dogs with similar physical characteristics (German wirehaired pointers (GWP), German shepherd dogs (GSD) and Labrador retrievers (LAB)) presented for routine hip dysplasia screening were recruited for the study. FHA, CFH and CrCdAR were measured and related to dysplasia status. Evaluations of FHA (p = 0.011), CFH (p < 0.001) and CrCdAR length (p = 0.003) measurements revealed significant interactions between breed, sex and FCI scores, so they had to be assessed separately. The results revealed that FHA tends to decrease as the hip dysplasia score worsens. There was no significant relationship between FHA and dysplasia assessment. FHA is breed-specific and is larger in normal and near-normal male (p = 0.001, p = 0.020) and female (p = 0.001, p = 0.013) GWP compared to GSD, respectively. FHA is greater in normal male GWP (p = 0.011) and GSD (p = 0.040) compared to females. There was a significant and strong positive correlation between FHA and CrCdAR in all breeds and sexes. Additionally, FCI scoring had a medium (GWP, GSD) to strong (LAB) negative correlation with CFH.
