Imaging Diagnosis—positive Contrast Peritoneographic Features of True Diaphragmatic Hernia

Abstract

A true diaphragmatic hernia is a congenital diaphragmatic malformation that can appear identical to a peritoneopericardial diaphragmatic hernia (PPDH). True diaphragmatic hernias are rare in dogs. Herein we describe the use of positive contrast peritoneography for diagnosis of a true diaphragmatic hernia in two dogs.

Congenital peritoneopericardial diaphragmatic hernia in a family of Persian cats

“…9 Over 100 cases have been reported in domestic pet cats, 1,2,10 with as many as 50% of these found incidentally, 2 and with a higher rate of incidental diagnosis occurring in mature and geriatric cats. 1,[11][12][13] Although not statistically significant, PPDH has been reported at a higher prevalence in males (55-63%). 1,2 Overall prevalence of PPDH in domestic cat populations has been reported to be 0.062-0.59%.…”

The impact of surgical timing and intervention on outcome in traumatized dogs and cats

“…Results of a PubMed search reveal that over the last 13 years, 22 articles pertaining to DH in dogs and cats have been published. Of these, 3 were specifically related to chronic DH, 6 are primarily imaging studies, and 3 are related to specific treatment modalities . Of the remaining 10 reports, 7 are case reports, 1 is a case series with 3 cats, and 2 are retrospective studies .…”

Radiographic and computed tomographic features of caval foramen hernias of the liver in 7 dogs: mimicking lung nodules

“…There have been many reports about congenital diaphragmatic disease including diaphragmatic eventration in dogs [4, 6, 10]. Unlikely in other diseases, diaphragmatic eventration is considered as the first differential to caval foramen hernia in terms of small diaphragmatic bulging on lateral radiographs, small breeds are predisposed, and the abdominal organ did not tend to prolapse into the thoracic cavity [4].…”

“…Unlikely in other diseases, diaphragmatic eventration is considered as the first differential to caval foramen hernia in terms of small diaphragmatic bulging on lateral radiographs, small breeds are predisposed, and the abdominal organ did not tend to prolapse into the thoracic cavity [4]. However, it has been known as a condition where the diaphragmatic muscle is malpositioned with subtotal diaphragmatic tears that do not occur at the central tendon or in the pericaval area because the fibrous tissue is stronger than the muscular portion of the diaphragm [4]. In addition, on radiographs, diaphragmatic eventration seems not to have a pericaval pattern, but rather a caudoventral mediastinal mass pattern [3] or entire hemidiaphragm displacement [17] that definitely differs from caval foramen hernia.…”
