The differential diagnosis of scapuloperoneal amyotrophy.
This report deals with a scapuloperoneal syndrome which developed simultanously with pain and distal paresthesias. In addition there was a slight sensory disturbance of glove and stocking type distribution. Motor conduction velocity was within normal limits and all distal latencies of response were normal; only the sensory conduction velocity of the left median nerve was found to be decreased (42.1 m/s). Electromyographic investigations revealed only signs of myopathy. Histological findings (m. deltoideus, m. tibialis anterior) favoured a primary myopathic process. Biopsy of the n. suralis revealed no certain pathological changes. The affection appears to have an autosomal dominant mode of inheritance. The sensory disturbance and decreased reflexes indicate an involvement of the nervous system, but the question of relationship to the scapuloperoneal muscular atrophy cannot yet be answered.
