Background:
Spinal subdural hematomas (SSH) are a rare cause of spinal cord compression. SSH following clipping of an aneurysm has only been reported once. We now report such a case and discuss the mechanism of SSH development after aneurysmal neck clipping.
Case Description:
A 32-year-old man complained of lumbago 7 days after craniotomy for the clipping of an aneurysm. Neurologic examination revealed no abnormality, but magnetic resonance imaging (MRI) demonstrated a lumbosacral spinal subdural hematoma. He received conservative management and his lumbago showed improvement. An MRI taken 19 days after surgery revealed a residual hematoma.
Conclusion:
The downward movement of blood from the cranial subdural compartment under the influence of gravity is the most appropriate explanation for SSH following craniotomy.
