发现脑袋里有两个动脉瘤十几年了，一直观察中，因为比较小而且没有增大，请版上的医生同学给个第二建议，谢谢 Narrative & Impression CT BRAIN ANGIOGRAM WO+W CONTRAST HISTORY: "two left ICA aneurysms." COMPARISON: CTA brain dated 10/21/2021 TECHNIQUE: Multiplanar noncontrast CT scan of the head. Contrast-enhanced CT angiogram of the brain with 3D multiplanar MIP reformats provided. CONTRAST: 95ml of iohexol (Omnipaque) 350 mg/mL inj 100 mL, administered intravenously without complications. Estimated Radiation Dose: The patient received the following exposure event(s) during this study, and the dose reference values for each are as shown (CTDIvol in mGy, DLP in mGy-cm). Note that the values are not patient dose but numbers generated from scan acquisition factors based on 32 cm (L) and/or 16 cm (S) phantoms and may substantially under-estimate or over-estimate actual patient dose based on patient size and other factors. PreMonitoring, CTDI(S): 6.2, DLP: 6.2;Monitoring, CTDI(S): 31, DLP: 31;Brain w/o, CTDI(S): 58.7, DLP: 1193.7;CTA Brain, CTDI(S): 39.9, DLP: 810.5 FINDINGS: CT BRAIN: The ventricles and sulci are normal in size. There are no areas of hypodensity to suggest recent cortical infarction. There is no mass effect or hemorrhage and no hydrocephalus. There are no abnormal extra-axial fluid collections. CTA BRAIN: The medially projecting small saccular aneurysm at the distal cavernous segment of the left internal carotid artery measures: 12/19/2023: 2.5 AP x 1.3 TR x 2.3 CC mm 10/21/2020: 2.5 AP x 1.5 TR x 2.3 CC mm 01/11/2017: 2.5 x 1.5 x 2.3 mm 11/03/2015: (CTA): 2.3 mm AP x 1.3 mm TR 03/26/2015: (CTA): 3.1 mm AP x 1.6 mm TR 10/12/2012: (CTA): 2.5 mm AP x 1.6mm TR 09/28/2010: (MRA): 2.1 x 1.7 mm 03/11/2010: (MRA): 2.5 x 1.7 mm The inferomedially projecting saccular aneurysm at the supraclinoid segment of the left internal carotid artery after the ophthalmic artery origin. The left carotid artery arises separate from the aneurysm. It measures: 12/19/2023: 3.6 AP x 4.4 TR x 3.4 CC mm 10/21/2020: 3.5 AP x 4.4 TR x 3.7 CC mm 01/11/2017: 3.5 x 4.3 x 3.7 mm 11/03/2015: (CTA): 3.1 x 4.1 x 3.2 mm (AP, TR, SI) 03/26/2015: (CTA): 3.3 x 3.3 x 3.3 mm (AP x TR x SI) 10/12/2012: (CTA): 3.1mm AP x 2.5mm TR x 3.1mm CC neck 2.5mm x 3.6mm 09/28/2010: (MRA): 4.4 x 3.2 mm 03/11/2010: (MRA): 4.1 x 2.6 mm The intracranial internal carotid arteries are otherwise unremarkable. A1 segments, anterior communicating artery, and A2 segments are unremarkable. M1 segments and major MCA branches are unremarkable. P1, P2 and proximal P3 segments are unremarkable. Vertebral arteries, basilar artery, and visualized cerebellar arteries are unremarkable. IMPRESSION: No significant changes in the size of the medially projecting saccular aneurysms at the cavernous segment and supraclinoid segment of the left internal carotid artery. Size and configuration of these aneurysms are stable since 2020 CTA brain. No new aneurysms.
