Pseudohypertrophy : Enlargement of a diseased muscle due to replacement by fat and fibrous tissue. Pseudohypertrophy occurs in some neuromuscular disorders, especially in the dystrophinopathies - Duchenne’s and Becker’s muscular dystrophy. Pseudohypertrophy occurs in other neuromuscular conditions as well, including juvenile proximal spinal muscular atrophy (Kugelberg-Welander disease), Kennedy’s disease, central core disease, centronuclear myopathy, limb girdle dystrophy, acid maltase deficiency, polymyositis, granulomatous myositis, facioscapulohumeral dystrophy, and inclusion body myositis. http://neurosigns.org/wiki/Pseudohypertrophy
