Signs and symptoms: History of meningioma. Syncopal episode today, balance problem for one week. Clinical question: Change of meningioma. Non-infused CT of brain:Small partially calcific meningioma along the right petroclinoid ligament is identified. Non-infused study is significantly less sensitive for detection of true measurements of meningioma. On this non-infused study meningioma measures approximately 13.7 mm in AP access and 10.6-mm in transverse axis (axial image 8). Considering the significant difference between the two studies of CT of brain today an MRI from 8 -- 28 -- 2009 no significant interval change can be appreciated. This mass is in contact with the right aspect of the pons with minimal flattening. This was noted on prior study as well. There is no evidence of edema of brain parenchyma adjacent to the meningioma. This non-infused CT examination of brain also demonstrates findings consistent with small vessel disease of indeterminate age. No intracranial hemorrhage is detected.
1.Small vessel disease of indeterminate age.2.Stable right petroclinoid meningioma and B. no appreciable change since prior MRI study. Please see above comments.3.No acute intracranial findings.
