title: Primary lumbosacral Wilms tumor associated with diastematomyelia and occult spinal dysraphism. A report of a rare case and a short review of literature.
abstract: BACKGROUND
  The occurrence of an extrarenal Wilms tumor in the lumbosacral region is an extremely uncommon condition.
  
  
  METHODS
  We report a case of Wilms tumor in the lumbosacral region that was associated with diastematomyelia and occult spina bifida. An 18-month-old girl presented with a swelling over the lower back with a tuft of hair on it, which she had had since birth. Imaging of the spine revealed spina bifida, bony diastematomyelia, and tethered cord. Excision of the bony spur and detethering of the cord was done. After a year, she had recurrence of swelling at the same site, weakness of both lower limbs, and incontinence of bladder and bowel. Excision of the mass and bony spur and detethering of the spinal cord were done. Histopathological examination showed features of a Wilms tumor.
