[Syringohydromyelia. Report of a case which resolved spontaneously].

OBJECTIVE To present a boy with syringohydromyelia associated with Chiari I malformation that showed spontaneous remission. CLINICAL CASE A boy with moderate short stature and discrete dysmorphic facial features was studied by cerebral and spinal magnetic resonance (MR). He showed syringohydromyelic cavities in cervical and dorsolumbar regions associated with Chiari I malformation. MR study was performed every year and collapse of both syringohydromyelic cavities was found four years after discovering the picture. CONCLUSION Spontaneous collapse of syringohydromyelia can be observed, though it occurs very seldom.
