[Occult intrasacral meningocele: case report]. / Meningocele intra-sacral oculta: relato de caso.

Intrasacral meningoceles are rare conditions that can cause symptoms of nerve root compression. We report a case of a 18-year-old female, who presented with urinary incontinence. The neurological and urological evaluation revealed lack of detrusor muscle reflex. This finding supported the hypothesis of spinal disraphism. Magnetic resonance image revealed an intrasacral meningocele. The patient was submitted to surgical excision of the lesion without postoperative complications. In the present paper, the pathogenesis, clinical picture, neuroradiological findings and surgical treatment are discussed.
