Introduction
Traumatic reticuloperitonitis and pericarditis is a frequently seen digestive tract condition in cow and buffaloes, however, rarely encountered in in sheep and goats (Maddy, 1954; Sojka et al., 1990). The condition results mostly following the swallow of small sharp metallic objects (foreign body) along with the feed. These foreign bodies may penetrate the reticulum and then further extends to diaphragm and pericardium (Haque et al., 1976; Brown et al., 2007). If foreign bodies do not cause perforation it can remain in reticulum without causing any harm (Brown et al., 2007). Multiple abscesses both in thoracic and abdominal organs are the sequelae of TRP (Sojka et al., 1990). Due to sever loss of production, affections of ruminants’ forestomach is gaining the currency all over the globe.

Case History
In this report an unfamiliar traumatic reticulo-pericarditis is described in a 2-year old female goat. A crossbred (Teddy) goat in comatose condition was present at the Intensive Care Unit (ICU) of the Department of Clinical Medicine and Surgery, University of Agriculture, Faisalabad (Pakistan). In anamnesis no significant information except the history of in-appetence from last 5 days, along with abducted forelimbs and reluctant to walk. Patient was kept on grazing along with its other heard-mates. Before any diagnosis/treatment started, animal died.

Necropsy Findings
Thoracic and abdominal findings were insignificant and all organs positioned normally. Both pericardium and fluid were devoid of any evidence inflammatory reaction, however, removal of pericardium revealed a 3 mm round necrotic spot on epicardium of left ventricle (Figure 1).

Upon exploring the spot, a 45 mm long quilt needle found fixed in the ventricular septum extended from left ventricle to right atrium (Figure 2).

Figure 2 A 45 mm long quilt needle can be seen fixed in the ventricular septum

The sharp end of the needle found fixed in bicuspid valve. The significant of this necropsy finding was the absence of any other abnormality (pericardial effusions, peritonitis etc.).

Discussion
As cattle do not properly masticate feed before swallowing and also do not discriminate between metal and feed material, so they commonly ingest foreign bodies (Braun et al., 2002). Presence of potentially injurious foreign bodies (sharp) in the feed/grazing is important in the development of the disease.

Perforation of reticulum by sharp penetrating foreign objects results in TRP (Sojka et al., 1990). Ruminal tympany and pregnancy results in increased intra-abdominal pressure, which facilitates the penetration of sharp foreign objects into reticulum and other thoracic/abdominal organs (Akkoç, 2007; Torki et al., 2011). Sharp foreign bodies perforating reticulum in carinoventral direction can cause Reticulo-pericarditis after penetrating from diaphragm (Sojka et al., 1990). Suppurative inflammation characterized by multi-locular abscessation of various organs located in abdominal and thoracic cavity is the complication of TRP (Sojka et al., 1990). Whereas Akkoç, 2007 had also described the presence of pyothorax as a possible complication of TRP along with abscess pouch in pericardial sac. In the present report no inflammation and abcessation was found in abdominal/thoracic cavity. Thickening of epicardium and pericardium are common lesions of TRP but in this case no effusions and thickening of pericardium and epicardium was found. In this report no other macro and microscopic findings related to forestomach diseases was found. Authors think that this report is of special significance, as goats are elegant in their eating habits and TRP is extremely rare condition reported. Despite the rareness of the condition in this species this disease should be given wattage due to related economic losses and poor prognosis (often death) (Çevik et al., 2010).
