Chronologic imaging findings with clinical correlations
| Time | Imaging Modality | Imaging Findings | Clinical Symptoms |
|---|---|---|---|
| 1994.3.24 | CT | Thickened right tentorium: hypodense on unenhanced and with strong enhancement | Decreased right vision |
| 1995.5.6 | MR imaging | Right tentorium thickening: hypointense on T1- and T2-weighted images and homogeneous contrast enhancement | |
| 1998.5.8 | MR imaging | Additional involvement of left tentorium, posterior falx, and right cavernous sinus | Right blindness, decreased left vision |
| 1998.6.30 | MR imaging | Regressive change of tentorium, falx, and cavernous sinus | |
| 1999.1.11 | MR imaging | Regressive involvement of tentorium but increased enhancement at right mastoid | Right hearing loss |
| 1999.2.8 | Temporal bone CT | Right mastoid cholesteatoma with tegmen and dural plate erosion, left mastoiditis | |
| 1999.12.18 | MR imaging | Progressive enhancement of left mastoid | Bilateral hearing loss |
| 2001.4.21 | MR imaging | No significant interval change of tentorium or mastoid involvement | |
| 2001.7.31 | CT | Ill defined enhanced left temporal lobe mass with perifocal edema | Delirium, disorientation |
| 2001.8.6 | Cerebral angiography | Faint stain at left temporal, no extra-axial tumor | |
| 2001.8.7 | MR imaging | Enhanced left temporal dural mass with mass effect of temporal lobe, poor opacified straight sinus |
