Split cord malformation type 1 with two hemicord lesions.

Split cord malformations are rare entities which may present in an occult manner or in association with other lesions or congenital anomalies. Rarely, these cases may have associated hemicord lesions. We report an unusual case, the first of its kind, a type 1 split cord malformation with two pathologically different lesions (lipoma and dermoid) on one hemicord.
