41 years Female (DOB:3/7/1975)Reason: 3 t scanner ccm protocol qsm/permialbility History: s/p resection of pontine cavernomaPROVIDER/ATTENDING NAME: ISSAM A. AWAD SURGEON W/ SCHED UCMC There is redemonstration of a mass centered in the right pons associated with a developmental venous anomaly. This mass is surrounded by signal loss peripherally and T1 and T2 signal hyperintensity and a popcorn-like appearance centrally. On T1 imaging it measures 14 mm in diameter. It is unchanged in size compared with previous exam. However, the intrinsic signal characteristics have changed there is more signal loss peripherally and the smaller T2 hyperintense component. The T2 hyperintense component measures 3 mm on the current exam and measured 10 mm on the prior exam. The patient status post right temporal bone surgery.There are subdural effusion present in the posterior fossa which was also present on the prior exam and does not appear to have changed substantially.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate mucosal thickening in the left maxillary sinus. There is partial opacification of the left frontal sinus and anterior ethmoid air cells. This was also present on the prior exam.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
The patient is undergone recent surgery for a pontine cerebral cavernous malformation. The inner component of the cerebral cavernous malformation is decreased in size. The adjacent hemosiderin deposition the course has not changed. A follow-up exam would help further assess this. This lesion associated with a developmental venous anomaly.
