CT evaluation of sigmoid plate dehiscence causing pulsatile tinnitus

Conclusion SPD causing PT has characteristic CT findings. It may be generated by vascular or intracranial pressure abnormalities and act as a common key to triggering PT’s perception. Key Points • Pulsatile tinnitus (PT) caused by sigmoid plate dehiscence (SPD) may be cured. • SPD causing PT has some characteristic findings on CT. • SPD may be a common key to triggering PT’s perception. • Thin-slice high resolution CT venography is recommended for SPD assessment. • The relationship between intracranial pressure and SPD causing PT should be studied.
