Ultrasonographic findings may be useful for differentiating interdigital abscesses secondary to migrating grass awns and interdigital furunculosis in dogs. Vet Radiol Ultrasound 2023; 64:920-929.

Abstract
Grass awn migration and furunculosis are common diseases in dogs that can lead to interdigital subcutaneous lesions with a similar clinical presentation, and occasionally similar ultrasonographic images, but different treatments are required. This retrospective, multicentric, analytical study aimed to determine whether epidemiological, clinical, and ultrasonographic features could be used to differentiate interdigital furunculosis and abscesses secondary to migrating grass awns. Fifty-nine dogs that underwent interdigital ultrasonography were included (interdigital furunculosis [IDF], n = 27; interdigital abscess secondary to a migrating grass awn [IAGA], n = 32). Ultrasonographic images were reviewed by two observers blinded to the diagnosis, who graded nine qualitative and four quantitative parameters for each patient. In both groups, pruritus/licking (IDF 74%, IAGA 70%), a discharging interdigital wound (63% for each group), and thoracic limb involvement (IDF 88%, IAGA 75%) were common features. On ultrasound, a subcutaneous multilinear hyperechoic main element was identified in most dogs (IDF 85%, IAGA 100%). The ability to display this element in a single plane (P < 0.01), the absence of additional hyperechoic linear elements in different planes (P < 0.01), and a surrounding hypoechoic halo (P < 0.05) were significantly more common in dogs with interdigital abscesses secondary to migrating grass awns. A cut-off value of 0.83 cm for the length of the main multilinear element provided a sensitivity of 91% and a specificity of 87% in the diagnosis of a migrating grass awn. Findings supported prioritizing a differential diagnosis of interdigital abscesses secondary to grass awns in dogs with these ultrasonographic characteristics.

Abstract
Migrating grass awns are an important cause of disease in dogs and cats. Plant awns can migrate into several body tissues and cavities because of their fusiform shape and backward-pointing barbs. Their migration causes inflammatory tissue reaction and clinical signs depend upon their localization. Ultrasound has been described as a useful, noninvasive, and readily available tool to identify and guide vegetal foreign bodies removal in animals. The aim of this systematic review was to summarize current knowledge on the application of ultrasonography in the identification and removal of grass awns from various anatomic locations in dogs and cats. We selected and analyzed 46 papers on the application of ultrasonography in dogs and cats affected by migrating grass awns. The ultrasonographic appearance of grass awns is characteristic, although their size and location can influence the visualization and the attempt of removal. In some cases, migrating grass awns are not directly visualized by ultrasonography, but the lesions caused by their migration can be easily seen. Ultrasonography can be considered a useful diagnostic tool to localize and remove migrating grass awns; however, when the migration occurs in less accessible locations or discrete foreign bodies are present, this diagnostic tool should be considered as a part of a multidisciplinary approach with advanced diagnostic imaging modalities.

Abstract
Objectives To describe the clinical presentation, management, and outcome of cases treated for septic peritonitis secondary to intra-peritoneal grass awn migration. Animals Six client-owned dogs and 1 client-owned cat. Procedures Clinical data of dogs and cats treated surgically for septic peritonitis secondary to an intra-peritoneal grass awn identified during surgery between January 2014 and December 2021 were retrospectively reviewed. Data included signalment, clinical presentation, blood test results, diagnostic imaging findings, surgical procedure, postoperative complications, and outcome. Telephone interviews were conducted for long-term follow-up. Results Six dogs and 1 cat met the inclusion criteria. The most common reported clinical signs were lethargy (n = 7), anorexia/dysorexia (n = 4), and pyrexia (n = 4). The vegetal foreign body was not identified in any case with ultrasound (0/5) and only suspected for one case with a computed tomography scanner (1/4). A grass awn was identified within an omental abscess for each case during surgery. Abscess resection for each case resulted in partial pancreatectomy and a splenectomy for 1 case, and partial gastrectomy for another case. All cases survived to discharge. Only one minor post-operative complication was identified, and no other complication was reported at the long-term telephone interview. Conclusion and clinical significance Septic peritonitis secondary to omental grass awn foreign body is an uncommon condition that has a good to excellent prognosis after surgical treatment. Identification of omental grass awn with ultrasound and computed tomography is rare. Therefore, particular care should be given to omental exploration during surgery for septic peritonitis with no underlying cause identified.

Abstract
Background: Intramural bladder foreign bodies resulting from migration of grass awns have rarely been described in the veterinary literature. Surgical removal should be considered the treatment of choice for symptomatic lesions. Case Description: A clinical case of a miniature poodle with increased urination and progressive hypoechoic mural nodules on repeat bladder ultrasound is described. An exploratory bladder surgery with excision of the two lesions was performed, allowing the extraction of a plant foreign body from the bladder wall. Conclusion: This is among the first cases in the veterinary literature in which a grass awn has been surgically extracted from the wall of the bladder in a dog. Differential diagnosis of intramural bladder lesions in dogs should include lesions caused by migratory plant awn foreign bodies.
