Original publication title: Computed tomographic findings in 44 dogs and 10 cats with grass seed foreign bodies.
Plain-English summary
A group of 44 dogs and 10 cats showed signs of discomfort due to grass seeds stuck in their bodies. Common symptoms included swelling, coughing, sneezing, and discharge, with many pets suffering for weeks or even years before treatment. A CT scan helped locate these grass seeds, which were often found in the chest or nasal cavity, but only a few were visible on the scans. Most pets had additional issues like fluid buildup or abscesses. After the grass seeds were removed, many pets likely felt relief from their symptoms.

Abstract
OBJECTIVE: To supplement recent reports of computed tomographic (CT) findings in dogs and cats with grass seed foreign bodies. METHODS: Retrospective review of cases that had CT scan and subsequent retrieval of a grass seed during the same period of hospitalisation from a site included in the scan. RESULTS: Records of 44 dogs and 10 cats were reviewed. Most were presented in the months July to December. Median duration of clinical signs was 4 weeks (range 2 days to 2 years). The most frequent clinical signs were soft tissue swelling (30% cases), coughing (28%), sneezing (28%) and discharge (26%). Grass seeds were retrieved from the thorax (35% cases), nasal cavity (31%), ear (7%), other sites in the head and neck (22%), sublumbar muscles (2%) and pelvic limb (2%). The grass seed was visible in CT images in 10 (19%) cases. Secondary lesions were visible in CT images of 52 (96%) cases, including collection of exudate (37%), abscess (24%), enlarged lymph nodes (22%) and pulmonary consolidation (20%). CT images appeared normal in 4% animals. CLINICAL SIGNIFICANCE: Grass seeds within the respiratory tract are frequently visible in CT images, but in general CT appears to be more useful for localisation of secondary lesions than as a method of definite diagnosis.
