Closed spinal dysraphism

Definition

A rare group of spinal dysraphisms, also referred to as spina bifida occulta, with a high variability in terms of severity,characterized by the absence of exposed neural tissue. The skin overlying the abnormality remains intact although the skin itself may be abnormal with features such as hairy patch of skin, crater or haemangioma. These skin features are known as the cutaneous stigmata of spinal dysraphism.
