[Value of neuromuscular biopsy in the child. Clinical, electrophysiologic and histopathologic correlations in 97 cases].
The authors tried to test the diagnostic yield of muscle and nerve biopsies in children and studied the relationships between clinical, electrophysiological and histopathological findings in 97 cases seen over a 3-year period. Specific histopathological lesions were described in 17.9% of muscle biopsies and 27.2% of nerve biopsies. In 65% of the cases, the biopsy revealed or confirmed the diagnosis, or specified the process (neurogenic or myogenic). Histopathology was concordant with clinical and electrophysiological findings in 83.5% of the cases.
