Abstract
BACKGROUND: Idiopathic intracranial hypertension (IIH) is a relatively rare syndrome of increased intracranial pressure of unknown etiology. It is characterized by cerebrospinal fluid (CSF) opening pressure more than 250 mmH2O, with normal cranial imaging and CSF content. IIH occurred after spinal surgery is extremely rare. METHODS: We present two IIH cases occurred after spinal surgery and conduct a systematic review of articles reporting IIH occurred after spinal surgery. RESULTS: The first patient underwent a posterior decompression and fixation for cervical fractures. IIH symptoms appeared 3 days postoperatively and gradually resolved with appropriate medication. The second patient underwent posterior spinal fusion with segmental instrumentation for congenital scoliosis. IIH symptoms appeared 5 days postoperatively and the patient died due to the irreversible intracranial hypertension although underwent intensive care and treatment. The literature review revealed that there were only five cases of IIH occurred after spinal surgery reported till date. CONCLUSIONS: IIH occurred after spinal surgery is relatively rare; the diagnosis is based upon exclusion of other diseases. IIH should be kept in mind in patients underwent spinal surgery as it could develop into irreversible intracranial hypertension.
