Question: is a congenital myopathy possible w/ a normal muscle and skin biopsy? my two year old had an EMG indicative of a myopathy, reduced reflexes, and very lax joints (mostly ankles. weakness is greater in legs and then shoulders, with some mild in trunk. )The surgeon performing the biopsy said she had much less muscle mass than he would have expected. She has been in PT for 16 mo and just started walking 2 mo ago. She has normal CK levels and we have done extensive blood work. Her biopsy just returned as normal, and I am wondering if it is possible to have a myopathy w/ a normal biopsy? I can't talk to her doc until august,and would love any thoughts on this.

Answer: Not an expert on this stuff, but I'll tell you what I know. It's possible that during the biopsy, they got a sample that--just by bad luck--didn't have any affected tissue. If your doctor's clinical suspicion is high, he may ask to repeat the biopsy. It's also possible that the myopathy is so mild that there would only be minimal findings on biopsy that might get missed. In medicine it's an unfortunate fact that there are exceptions to nearly every rule. Although biopsies are generally pretty solid as diagnostic tools, there's no such thing as a test that is 100% perfect. That's why we still need doctors to look at the whole patient and weigh all the findings together.
