A 32-year-old female has a slowly progressive difficulty
in climbing stairs and getting up from the seated position. On examination
there is evidence of proximal muscular weakness affecting the pelvic girdle
more than the shoulder girdle. She undergoes many investigations and
ultimately a muscle biopsy is performed and this shows large vacuoles, which
stain positive for periodic acid-Schiff stain.
This patient has:
a)
Becker muscular dystrophy
b)
Duchenne muscular dystrophy
c)
Polymyositis
d)
Polymyalgia rheumatica
e)
Acid maltase deficiency
