A two-year-old female neutered Whippet was referred for evaluation of progressive right pelvic limb lameness. Clinical examination revealed a fibrous band palpable along the cranial aspect of the quadriceps muscle group, and signs of discomfort on extension of the right hip. Computed tomography and ultrasonographic examination revealed mineralization of the tensor fascia lata muscle with enthesophytosis of its origin. Surgical exploration confirmed a fibrous band affecting the cranial border of the tensor fascia lata muscle. Resection of the band resulted in complete resolution of clinical signs. Histopathology was consistent with a fibrotic myopathy. To the authors' knowledge, this is the first case of a fibrotic myopathy affecting the tensor fascia lata muscle in the dog.
