Nemaline myopathy is a rare pathological process occasionally observed microscopically in a number of myopathic diseases in dogs.
Clinical symptoms in affected dogs include exercise intolerance and muscle weakness. Adult-onset cases often present with lethargy, inappetence, weakness, abdominal distension and generalised muscle atrophy.
Electromyography usually shows mild to moderate diffuse spontaneous activity.
Diagnosis of nemaline rod myopathy requires muscle biopsy, showing the presence of numerous pathognomonic rods within muscle tissue.
There is no known treatment for this condition.
