Understand basic embryological facet behind etiology of spinal dysraphisms. Review various terminology and classifications of spinal dysraphisms. Pictorial review of commonly encountered cases Pictorial review of split cord malformation with commonly encountered associations
Spinal dysraphism encompasses large spectrum of congenital spinal and vertebral anomalies occurring at different level of embryological development. Schematic diagram correlating with embryogenesis and typical MR imaging appearance helps in better understanding the condition. Majority of patients come with non-specific neurological symptoms.

Findings and procedure details
Spinal dysraphisms refer to congenitalanomalies of the spine and spinal cord.
It is commonly encountered with an approximate incidence of 0.05 to 0.25 per 1000 births . Terminology: OPEN spinal dysraphism: is characterised by exposure of the nervous tissue and/or meninges to the environment through a congenital bony defect. CLOSED spinal dysraphism: There is no exposed neural tissue,
although cutaneous stigmata,
such as a hairy nevus or capillary hemangioma may be present.
Some are not...
Spinal dysraphisms are routinely encountered in day-to-day clinical practice in this era of increased cross sectional imaging. Basic knowledge of normal embryology is a must to understand pathogenesis of spinal dysraphisms. Thorough idea of terminologies,
classification and associated anomalies of spinal dysraphism is must know for all radiologists. Most of the anomalies are surgically correctable with significant neurological improvement,
so early diagnosis of the condition with associated...
