During their childhood, this patient underwent some kind of surgery in the lumbosacral region  (probably myelocoele), but he didn't present any documents about that intervention.

Now he has urinary incontinence, intermittent weakness of lower extremities and lower back pain, so he underwent MRI of endocranium which was unremarkable, as well as LS spine MRI which shows spinal cord extending to the level of S3 and was attached to a heterogeneous mass, which probably presents with a mixture of fat and scar tissue.
