Plain-English summary
A 9-year-old Cairn Terrier was brought in because it had been limping on its right front leg for three months, and pain medications weren't helping. Tests showed very high levels of a muscle enzyme, and further examinations ruled out bone or blood vessel issues. Eventually, the vet found that the dog had a muscle infection caused by parasites and fungi. After starting treatment with medications called albendazole and itraconazole, the dog's condition improved significantly, and it was able to move more comfortably.

Abstract
A 9-year-old Cairn Terrier was presented for a right thoracic limb lameness of 3-month duration resistant to anti-inflammatory pain treatment. Blood chemistry revealed a highly elevated creatine kinase activity. An orthopedic or vascular etiology of the lameness was excluded by radiographs, computed tomography, and magnetic resonance imaging. Further workup for a neurologic or muscular etiology by electromyography, nerve conduction velocity measurement, and histology of muscle as well as nerve biopsies identified the cause of the lameness. Histology revealed a pyogranulomatous, necrotizing myositis with parasites of the species. Furthermore different developmental stages of fungi were detected which were identified assp. Treatment with albendazole and itraconazole significantly improved the patient's clinical signs.
