Idiopathic cervical spinal subdural haematoma: a case report and literature review

Abstract

This report describes a case of idiopathic cervical spinal subdural haematoma (SSDH) in which the haematoma was spontaneously absorbed without any treatment. A 68-year-old male patient presented with persistent neck pain and no obvious cause. Magnetic resonance imaging (MRI) revealed a space-occupying lesion at the C4–T1 levels. The lesion was initially misdiagnosed as a tumour. An operation was arranged to remove the tumour, but a preoperative computed tomography scan showed no obvious abnormal soft tissue density in the cervical spinal canal. Repeat enhanced MRI showed degeneration of the cervical vertebrae, but no obvious abnormal soft tissue density and no obvious enhanced signals in the cervical spinal canal. Spontaneous resolution of an idiopathic cervical SSDH was considered. Idiopathic cervical SSDH without obvious neurological symptoms are difficult to diagnose, so suspected cases should be carefully monitored. If the neurological symptoms grow progressively more debilitating with time, emergency surgery might need to be considered. To avoid unnecessary surgery, conservative management should be an option for patients with minimal neurological deficits and re-examination with MRI could be the best way to observe the dynamic changes taking place in the idiopathic cervical SSDH.
