Acute Pancreatitis Associated With Peritoneal Migration of Grass Awn in Two Dogs

Abstract

A 12 year old male Fox Terrier (case 1) and a one year old female Poodle (case 2) were presented with a history of dysorexia and vomiting, and case 2 also with distress associated with eating. Both dogs were diagnosed with acute pancreatitis based on clinical signs, blood analysis and ultrasonography which revealed the presence of a vegetable foreign body in the proximity of the pancreatic right lobe. Laparatomy enabled the gramineae awns to be removed which led to full resolution of clinical signs. We believe that these are the fi rst reported cases of acute pancreatitis due to grass awns.

Clinical and clinicopathological characteristics, treatment, and outcome for dogs and cats with confirmed foxtail foreign body lesions: 791 cases (2009–2018)

“…Therefore, the finding of pneumothorax or pyothorax in small animals in a geographic area with a high rate of foxtail‐associated disease should prompt consideration of this etiology. Additionally, intrathoracic foreign material has been reported to migrate through the diaphragm into the abdominal cavity, and concurrent evaluation of the abdomen is recommended in patients with foxtail‐associated intrathoracic disease 11,14,34 …”

Sublumbar grass awns in two cats: ultrasonographic features and ultrasound-guided retrieval

“…1 Because most affected dogs show aspecific clinical signs, grass awn migration should be always considered as a differential diagnosis in patients living in areas where the disease is present. 1,2,4-7, [14][15][16][17][18][19][20][21][22] Both cases presented in this report showed thoracoabdominal wall abscesses as the presenting complaint, but no previous clinical signs reported by the owners were suggestive of sublumbar grass awn migration as the inciting cause.…”

“…Grass awns can be differentiated from wooden foreign bodies because of their linear spindle shape and multiple parallel, hyperechoic linear interfaces. 2,5,7,14,17,20,21,23 Distal acoustic shadowing is a constant ultrasonographic feature of wooden foreign bodies, but it is not always present in plant awns (depending on their composition/thickness and on the angle of insonation); it is most likely to be seen in transverse views rather than in longitudinal views. 24 Once diagnosis was established, ultrasonography proved to be useful in therapeutic planning by allowing assessment of the feasibility of non-surgical retrieval.…”

Ocular and oral lesions caused by Tacinga inamoena in sheep and goats in Northeast Brazil

“…Thus, it would appear that these foreign bodies caused chronic inflammation only at those sites at which there was direct contact. In this regard, however, the findings of several studies have indicated that subsequent to chewing, the migration of plant stems can cause lesions, such as arteritis, meningoencephalitis, and uveitis (Sorden & Radostits 1996); abscesses in the central nervous system (Linon et al 2014); suppurative parotitis (Sinopidis et al 2011); and pancreatitis and peritonitis (Citi et al 2017).…”
