Original publication title: Acoustic radiation force Impulse elastography to aid diagnosis of two canine malignant peripheral nerve sheath tumors

Plain-English summary
Two dogs with lameness in their front legs were brought to the vet after not improving with other treatments. During the exams, one dog showed muscle wasting in its leg, and ultrasound revealed irregular lumps in both dogs. A special imaging technique called ARFI elastography indicated that these lumps were likely cancerous. Both dogs underwent amputation of the affected limbs, and tests confirmed they had malignant peripheral nerve sheath tumors. The imaging techniques helped the vets diagnose the issue and decide on the best treatment.

Abstract
ABSTRACT: This report described the use of acoustic radiation force impulse (ARFI) elastography in the diagnosis of two cases of canine malignant peripheral nerve sheath tumors. Both patients presented with lameness in the thoracic limb and no response to previous clinical treatment or trauma history. Physical examination revealed muscular atrophy in one of the thoracic limbs, in both dogs. B-mode axillary ultrasound showed the presence of a predominantly hypoechogenic, heterogeneous, irregular, nonencapsulated nodule with adjacent reactivity, measuring approximately 20.1 mm x 15.4 mm in the first case and 18.3 mm x 10.7 mm in the second. ARFI elastography was performed, showing areas of significant stiffness, with an average shear wave velocity of 4.12 m/s (case 1) and 4.35 m/s (case 2), suggesting malignancy. In both cases, the affected limb was amputated, and the tumors sent for histopathological analysis, which were; subsequently, diagnosed as malignant tumors of the peripheral nerve sheath. The ultrasonographic methods used were essential in the diagnosis and therapeutic conduct.
