1 23-year-old man with a left-sided temporal arachnoid cyst, suffering from occasional headaches.
23-year-old man with a left-sided temporal arachnoid cyst, suffering from occasional headaches. A, Transverse T2-weighted SE image (2000/80/1) shows a hyperintense left temporal arachnoid cyst.B, Coronal PSIF image (20/25/1) depicts distinct signal reduction (arrow) arising from the basal cisterns, indicating probable communication.C, CT cisternogram (3-hour delay) shows slight contrast enhancement within the cyst, confirming slow communication. The contrast enhancement was confirmed by measuring a clear increase of intracystic HU. The site of communication was not detectable on the CT cisternogram owing to proposed valve mechanism with slow communication. Karl T. Hoffmann et al.
