Bilateral subdural hematomas after dural puncture: delayed diagnosis after false negative computed tomography scan without contrast.

Abstract	BACKGROUND. Dural puncture secondary to spinal anesthesia or unintentional dural puncture during attempted epidural anesthesia can lead to headaches complicated by bilateral subdural hematomas. Routine computed tomography scan may not elucidate bilateral subdural hematomas in the isodense phase. CONCLUSION. Computed tomography scans with contrast media or magnetic resonance imaging may be necessary to diagnose bilateral subdural hematomas.
