An unusual case of 4 level spinal dysraphism: Multiple composite type 1 and type 2 split cord malformation, dorsal myelocystocele and hydrocephalous.

The authors here have reported a rare case of a child with a complex spina bifida with two different levels of split cord malformation (SCM) type 1 and single level type 2, a non terminal myelocystocele, coccygeal dermal sinus, bifid fatty filum and hydrocephalus, which substantiates the neuroenteric canal theory and have further tried to highlight the importance of complete Magnetic resonance imaging (MRI) screening of the whole spine and brain with SCM to rule out other associated conditions. The patient was admitted with a leaking myelocystocele with bilateral lower limb weakness. MRI of whole spine with screening of brain was done. Patient underwent 5 operations in the same sitting- (According to classification given by Mahapatra et al.) removal of SCM type 1a at D7-8; removal of SCM type1c at L2-3; removal of SCM type 2 at D10; repair of non terminal myelocystocele at D6-D10; low pressure ventriculoperitoneal shunt on right side with excision of dermal coccygeal sinus; and, excision of bifid fatty filum. The clinicoradiological findings in our patient further substantiate the multiple accessory neuroenteric canal theory in the development of composite type of SCM. The physical and neurological signs of SCM and nonterminal myelocystocele should prompt the neurosurgeon to consider performing the screening MRI of whole spine with brain to rule out other composite types of SCM and hydrocephalus.
