[The differential diagnosis of syringomyelia from pseudosyringomyelitic ulcero-mutilating acropathy].

The authors describe some differential diagnostic criteria of atypical syringomyelia and pseudosyringomyelitic acropathy. It was found that trophic disorders in the skin, metatarsal bones were in atypical syringomyelia usually associated with sensibility disorders of the dissociated type in the zone of corresponding segments. In pseudosyringomyelitic acropathy trophic and skin changes precede sensibility disorders and do not always correspond to innervation zones of the lower extremities. Dysraphic state is of importance for the diagnosis of syringomyelia.
