“…Several investigators have demonstrated that current multidetector scanners have a spatial resolution that can reliably diagnose aneurysms greater than 4 mm with nearly 100 % sensitivity [16][17][18]. A meta-analysis that surveyed studies performed on 64-slice CT scanners with sub-millimeter resolution used for detection of cerebral aneurysms showed a pooled 97 % sensitivity rate for all aneurysm sizes [19]. For aneurysms 3 mm and smaller, however, early CT technology has been shown to be inadequate, with sensitivity numbers as low as 84 % from four-channel multi-row detector CT scanners (Fig.…”

Neuroimaging is a critical element in evaluating and treating patients with cerebral aneurysms. Each neuroimaging technique has unique strengths, weaknesses, and current developments. In this review, we discuss the utility of two primary noninvasive radiological techniques-computed tomography angiography (CTA) and magnetic resonance angiography (MRA)-as well as of digital subtraction angiography (DSA) for evaluation of cerebral aneurysms. These techniques allow comprehensive evaluation of aneurysm size, location, rupture status, and other imaging characteristics that guide clinicians to make appropriate and timely treatment recommendations.

“…5 phy sensitivity and specificity as 100 % (18). In a meta analysis by Guo et al, a sensitivity of 97% and specificity of 91% was found for 64-slice CT angiography (19). The sensitivity, specificity and accuracy of CT angiography were 95.1%, 94.1%, and 95%, respectively in Donmez et al study (14).…”

Background: The existence of residual aneurysm after intracranial aneurysm clipping bears the risk of re-bleeding, which worsens with the passage of time. Digital subtraction angiography (DSA) is accepted as the gold standard for evaluation of residual aneurysm, but it is invasive, costly, and serious complications are possible. Objectives: The aim of this study was to compare DSA to 64-slice CT angiography for assessing residual aneurysm. Patients and Methods: Forty patients with 43 clipped aneurysms from which 36 were torn, were evaluated by DSA after improvement in clinical status, and after a month they were evaluated by 64-slice CT angiography. The pictures were assessed by two neuroradiologists separately, in terms of quality, artifact due to the clips, and the completion of aneurysm closing. Results: In multislice computed tomographic angiography (MSCT) analysis, 36 pictures (90%) had good quality and four pictures (10%) had poor quality. In case of good quality pictures in MSCT and angiography, the 2-and 3-millimeter residual aneurysms were approved for two patients based on which, sensitivity, feature and positive/negative predictive value for diagnosis of residual aneurysm was 100 for good-quality pictures by MSCT. The level of agreement between the two neuroradiologists was 1 for diagnosing residual aneurysm and 0.86 for vasospasm. The average time for doing MSCT was 12 minutes compared to 45 minutes for DSA angiography, which was cost effective. Conclusion: CT angiography is a less invasive method with high sensitivity and capabilities for diagnosing residual aneurysm. It is cheaper, quicker and can be accomplished for critical patients. Therefore, it can be taken as the first choice and a replacement for DSA in post-surgery evaluation of patients with clipped brain aneurysm.

“…CTA is a non-invasive, fast, and readily available modality with sensitivity as high as 97%. 7 However, sensitivity decreases to 60% for aneurysms 4 mm or smaller. 8 Specificity of CTA varies in the literature; some studies report false positives as high as 20%, especially for aneurysms smaller than 5 mm or for those in the region of anterior communicating artery.…”

Azygos anterior cerebral artery shield masquerading as an aneurysm

et al. 2023

Here, we describe a case of a woman suspected to have an anterior cerebral artery (ACA) aneurysm that was ultimately found to have an azygous ACA shield. This benign entity highlights the importance of thorough investigation with cerebral digital subtraction angiography (DSA). This 73-year-old female initially presented with dyspnea and dizziness. CT angiogram of the head suggested an incidental 5 mm ACA aneurysm. Subsequent DSA demonstrated a Type I azygos ACA supplied by the left A1 segment. Also noted was a focal dilatation of the azygos trunk as it gave rise to the bilateral pericallosal and callosomarginal arteries. Three-dimensional visualization demonstrated a benign dilatation secondary to the four vessels branching; no aneurysm was noted. Incidence of aneurysms at the distal dividing point of an azygos ACA ranges from 13% to 71%. However, careful anatomical examination is imperative as findings may be a benign dilatation for which case intervention is not indicated.
