Pelvis X-ray:
1. Hypogenesis and deformity of sacrococcygeal spine with right
   side curvilineal deviation (red line in fig.01), in favor of
   caudal regression syndrome (mild form).

MRI of pelvis and spine:

1. Marked short T1 signal along thick filum terminale with slight
   downward displacement of conus medullaris to the level of
   L2/3, suggesting fibrolipoma of the filum terminale with
   tethered cord (fig.02).
2. Mild dilatation of central canal of spine along T10-L1,
   in favor of hydromyelia (fig.03).
3. Saddle-shaped thickening of the fundus of uterus with normal
   fundal external contour and with mild increased transverse
   diameter of uterine cavity, in favor of arcuate uterus (fig.04).

Impression:
1. Fibrolipoma of the filum terminale with tethered cord
   and hydromyelia.
2. Caudal regression syndrome with hypogenesis and deformity of
   sacrococcygeal spine.
3. Arcuate uterus.

Chromosome analysis: Terminal deletion of the chromosome 7q36 (not showed).
