Spontaneous resolution of Chiari I malformation and associated syringomyelia following parturition.

摘要

Spontaneous resolution of Chiari malformation and syrin-gomyelia following normal delivery has not been reported to date. We are reporting one such rare case and discuss the putative mechanisms of this event.Case report: A 24-year-old woman presented in March 2009 with a 3-month history of headache and 2-month history of hoarseness of voice. On examination, her higher functions were normal. The gag reflex was decreased on the left side and there was left vocal cord palsy. There was no other neurological deficit. MRI revealed Chiari I malformation with peg-shaped tonsils herniating up to C 2 {arrows in Fig. la, b) with associated syringomyelia extending from C 3 to T 4.
