Clinically, the animal exhibited poor general condition characterized by weakness and dyspnea. At necropsy; ascites and local fibrinous peritonitis were observed. There were severe adhesions between thoracal cavity, diaphragma and reticulum in which antero-ventral region corroded needle of 5 cm length. In thoracal cavity, there were fibrinopurulent exudate and fibrinous adhesions between pericardium and left apical lobe of the lung. In the pericardial sac, cardiac tamponade resulting from excessive clotting was observed. Furthermore, several abscesses were determined in the reticular wall and thoracal cavity Histopathologically, fibrinopurulent inflammatory reaction was detected in the wall of the reticulum, pericard, epicard and lung. Keywords: Goat, pathology, traumatic reticulopericarditis. Bir Keçide Traumatik Retikuloperikarditis Bu çalışmada bir keçide rastlanan traumatik retikuloperikarditis olgusu tanımlandı. Olguda, klinik olarak genel sağlık durumunda kötüleşme ve solunum güçlüğü, makroskobik olarak, karın boşluğunda sıvı birikimi ve lokal fibrinli peritonitis gözlendi. Retikulumun anteroventral bölgesi ile diyafram arasında şiddetli fibröz yapışmalarla birlikte 5 cm uzunluğunda paslı bir iğne vardı. Gögüs boşluğunda purulent bir eksudat, akciğerin sol apikal lobu ile perikard arasında da fibröz yapışmalar belirlendi. Perikard boşluğunda aşırı kanamaya bağlı kalp tamponadı tablosu gözlendi. Gögüs ve karın boşluğunda ayrıca çok sayıda apselere rastlandı. Histopatolojik olarak, retikulum, perikard, epikard ve akciğerlerde fibrinopurulent yangısal bir reaksiyon gözlendi. Anahtar kelimeler: Keçi, patoloji, traumatik retiküloperikarditis. Introduction Traumatic reticulopericarditis results from injury or perforation of the reticulum and pericardium by sharp foreign bodies (1, 2). Foreign bodies such as nail, piece of wire, or needle are ingested with feed and reach the reticulum. The objects causing no perforation might remain in the reticulum for some time without causing harm (2). However, objects which pass through the reticulum can cause bleeding, abscess and adhesion in surrounding tissues and organs (3, 4). Objects which proceed in a cranioventral direction may cause reticulopericarditis by perforating the diaphragm or the pericardium (1, 5). Although reticulopericarditis is known to occur in cattle, it is rarely observed in small ruminants (6-8). The present study identified a case of reticulopericarditis in a goat with macroscopic and microscopic findings. Case History In this study, an 19-month-old female goat was observed to have deteriorated in general condition, with excessive weight loss and dyspnea, and the necropsy was performed. The tissue samples from visceral organs such as heart, lungs, liver, reticulum, peritoneum were fixed in 10% neutral buffered formalin, embedded in paraffin, tissue sections were stained with hematoxylin and eosin (HE). Macroscopically, 200 ml of yellowish ascitic fluid with fibrin clots was observed in the abdominal cavity. The reticulum, liver, diaphragm and peritoneum contained numerous fibrous adhesions. A rusty needle, 5 cm in length, which reached to the pericardium, was found (Figure 1). There were also many abscess foci in adhesion areas. Approximately 1000 ml fibrinopurulent exudate was observed in the thoracic cavity. The left apical lobe of the lung was found to be hepatized (Figure 2). Between the pleura and pericardium, there were greenish to yellow fibrous adhesions and abscess foci. Cardiac dilatation, pericardial thickening and cardiac tamponade resulting from excessive clotting in the pericardial sac were observed (Figure 3). Furthermore, there was petechial hemorrhage of the endocardium. Microscopically, neutrophil leukocytes, macrophages, a few lymphocytes, fibrin fibriles and a proliferation of connective tissue were found in the pleura, epicardium and pericardium. The inflammatory reaction was more severe in the pericardium. Variably sized abscesses surrounded by a wide zone of fibrous capsule were seen in the affected * IV.
