Multiple idiopathic fibrotic myopathies, including the tensor facia lata muscle, in a cat

: To describe the clinical features and treatment of a cat that was initially presented with fibrotic myopathy affecting the left tensor fascia lata. Approximately 5 months later, the cat was presented again with multiple idiopathic fibrotic myopathies, affecting the ipsilateral rectus femoris and the contralateral semitendinosus muscles. These were each separate lesions and occurred without known history of trauma. Surgical resection of the fibrotic portion of the affected muscles resulted in immediate, but not long-term, resolution of clinical signs.
