Acute, Nontraumatic Spontaneous Spinal Subdural Hematoma: A Case Report and Systematic Review of the Literature

الملخص EN

Spontaneous spinal subdural hematoma (sSDH) is a rare condition outright.

Moreover, cases that occur spontaneously in the absence of an identifiable etiology are considerably less common and remain poorly understood.

Here, we present the case of a 43-year-old man with spontaneous sSDH presenting with acute onset low back pain and paraplegia.

Urgent magnetic resonance imaging identified a dorsal SDH from T8 to T11 with compression of the spinal cord.

Emergent T8–T10 laminectomies with intradural exploration and hematoma evacuation were performed.

However, despite prompt identification and appropriate action, the patient’s recovery was modest and significant disability remained at discharge.

This unique and unusual case demonstrates that spontaneous sSDH requires prompt surgical treatment to minimize associated morbidity and supports the association between the presence of severe neurological deficits upon initial presentation with less favorable outcomes.

We performed a comprehensive systematic review of spontaneous sSDH of unknown etiology, which demonstrates that emergent surgical intervention is indicated for patients presenting with severe neurological deficits and the presence of these deficits is predictive of poor neurological outcome.

Furthermore, conservative management should be considered in patients presenting with mild neurological deficits as spontaneous resolution followed by favorable neurological outcomes is often observed in these patients.
