Cervical split cord malformation (diastematomyelia) with associated Klippel-Feil deformity presenting in adulthood with bimanual synkinesis.
Goacher et al., Eur Spine J 2024

New Information: This case report introduces a rare instance of an adult diagnosis of isolated segmental cervical split cord malformation (SCM) at the C4-C7 level, with the unique presenting symptom of bimanual synkinesis, which is involuntary mirror movements of one hand that mimic voluntary movements of the other hand.
Importance: SCM is typically diagnosed in children, making this adult diagnosis noteworthy. The case emphasizes the need for awareness among healthcare professionals about SCM as a potential diagnosis in adults with spinal issues, despite its rarity.
Contribution to Literature: The report contributes to the existing literature by documenting an uncommon adult presentation of SCM and by describing the associated clinical feature of bimanual synkinesis, which has not been commonly linked to SCM. It also underscores the significance of considering congenital spinal anomalies in differential diagnoses for adults with unexplained spinal symptoms.
