An unusual presentation of occult spinal dysraphism

Occult spinal dysraphism can lead to irreversible neurological complications, early diagnosis and treatment are necessary. It can be suspected from the presence of any cutaneous abnormality. We report a case with bony spur formation on the top of the 5th lumbar vertebra spinose process covered with skin mimicking a meningocel sac. By the help of this bony spur tethered cord could be diagnosed before any neurological deficit.
