Pericardial Diaphragmatic Hernia in a 2-year-old FS DLH cat: Our Case Of the Month January 2019
Wait, that's not supposed to be there...
Working in mobile ultrasound, you just NEVER know what you're going to see!
January's Case of the Month had quite an interesting presentation. Imaging was performed by technician Amanda Lacey, SDEP™ Certified Sonographer of Animal Sounds NW in Oregon. Her thoroughness, flexibility and problem-solving skills helped this patient get a quick diagnosis.
When Cardiomegaly is not 'Cardiomegaly' what do you do?
After following the SDEP™ Echo 7pt. protocol, go back to the 'not normal regions' and image from multiple different angles, put color on it, reposition the pet, and when you are still stumped, you phone a friend.
After checking images on the SonoPath clinical search for suspected hernia, Amanda decided to reach out to SonoPath specialist, Dr. Mac Daniel, DVM, DABVP, for some input on the next best step.........an Abdominal Ultrasound.
Taking a look into the abdomen helped put the clinical picture altogether resulting in a diagnosis.
Special thanks to Dr. Yuko Eguchi-Coe of West Hills Animal Hospital, Corvallis, Oregon,for allowing ASNW to be part of this patient’s diagnostic work up.
A 2-year-old MN DLH cat presented for lethargy. CBC/Chem/UA showed BUN of 41, urine specific gravity 1.041, 2+ proteinuria, urine culture (+) for Staphylococcus. Generalized cardiomegaly was noted on radiographs in addition to subnormal renal size.
The spleen was slightly enlarged and mildly irregular measuring 1.44 cm with minor, heterogenous parenchymal changes and scalloping contour. The liver and falciform fat in this patent were displaced cranially as was the stomach. Portions of the liver and falciform fat were herniated through the diaphragm. It appears that mainly fat has entered into the pericardium. However, herniated liver appears to occupy the caudal thorax. The abdominal fat herniated into the pericardium and occupied the heart base. However, it did not enter circumferentially around the pericardium. The herniated tissue appears to measure 5.0 x 4.0 cm. Diaphragmatic hernia was present and measured 2.0 cm. The stomach was displaced. Normal cardiac function.
Currently, the patient is stable and treatment options are being explored.
