Rest of the patients with spinal dysraphism had dermoid at conusmedullaris/intraspinaldermoid, low- lying spinal cord, diastometomyelia, tethered spinal cord, lipoma, dermal sinus
and tight filumterminale as the cause of neurogenic bladder (Figures-1-6).
Particularly in the presence of dermal sinus
, meningitis or spinal abscess may develop.
