“…Combining clinical and MRI findings helps in making a proper diagnosis in most cases [1], [2], [3]. In fact, MRI examination revealed the appearance of a partial thrombosis of the aneurysmal sac[8], well-showed in T2-weighted images and an enlargement of the left CS with a heterogeneous enhancement in T1-weighted images after contrast medium administration. Postcontrast MRI also showed enhancement of the surrounding pachimeninges.…”

We report the uncommon case of an acute cavernous sinus syndrome in a patient who was consequently discovered to have both a cavernous internal carotid artery aneurysm and bacterial meningitis. Which came first, the chicken or the egg? Which of the two, the aneurysm or the meningitis, gave rise to the patient’s symptoms? We briefly reviewed the literature of similar cases and tried to analyze the possible pathophysiological relationship between these findings. Moreover, this case highlights the importance of a multidisciplinary management of these patients to better decide between a medical and a surgical and/or endovascular treatment.

“…However, it is not possible to extrapolate these results in patients because of certain limitations in the methodology (Boleaga-Durán et al, 2004;Li et al, 2011). Moreover, CTA is the current method for initial assessment of cerebral circulation in suspected acute stroke or subarachnoid hemorrhage and the technique of choice for the evaluation of aneurysms (Zhang et al, 2012;Cirillo et al, 2013). We have not found studies using CTA in Mexican population.…”

SUMMARY:One of the most common causes of stroke is rupture of aneurysms whose approach requires knowledge of anatomical variants. The aim of this study was to determine the prevalence of anatomical variants of the anterior cerebral artery (ACA) and the anterior communicating artery (AComA) by 3D computed tomography angiography (3D CTA) in Mexican individuals. A retrospective, observational, cross-sectional descriptive study of 283 patients, independent of sex or age, in which morphometric measurements of cerebral vessels were evaluated using contrasted 3D CTA from a period of two years was performed. We found at least one "atypical" variant in a third of the study population (33.93 %). The most common "atypical" variant was the absence of the AComA (14.1 %). A significant association between the hypoplastic variant of the right A1 segment and hypoplasia of the left A1 and the right A2 was found, while hypoplasia of the left A1 was associated with hypoplasia of the right A2. There is a difference in the prevalence of anatomical variants of the ACA-AComA complex in Mexican population in relation to other populations. The typical variant is the most prevalent form in the study population. However, the presence of atypical variants represents an important number that should be taken into account in clinical and surgical procedures.

“…Data from the literature are partly incoherent in showing the advantage of CEMRA in aneurysms patency depiction, partly due to the small sample size in the series [3,4,6,7,9,10,12]; nevertheless there is a general agreement in recognizing the advantage of contrast acquisitions in the better depiction of aneurysm remnant either small or large.…”

Background: The role of 3DTOF MRA in the follow up (FU) of coiled cerebral aneurysms is well established. Though CEMRA (Contrast Enhanced Magnetic Resonance Angiography) has demonstrated to be superior to 3DTOF MRA in showing aneurysms residual patency, its role is still debated. The aim of this study was to verify if there is an added value of CEMRA in the long term follow up of coiled treated aneurysms. Methods: Sixty-four cerebral aneurysms treated with GDC coils regularly followed up with 3DTOF and CEMRA at 3T every year for at least four years were included in the study. Both MR exams were evaluated and scored according to Montreal scale. Residual patency rates and modifications during follow up as depicted by the two techniques on the three item score of the Montreal scale (TO = total occlusion, NR = neck remnant and AR = aneurysm remnant) were registered along with management decisions. Intertechnique agreement was evaluated with respect to patency scoring in earlier and later stages of FU. Moreover the predictive value of earlier scores for both acquisitions with respect to management decision was assessed. Results: At 1 year FU, TO to NR to AR score ratios were 31/23/10 and 22/31/11 for 3DTOF and CEMRA respectively, whereas at 4 years FU they evolved to 28/22/14 and 19/28/17 respectively. Fifteen patencies (all AR) out of 64 aneurysms were judged suitable of retreatment evaluation during FU and 8 retreatments were effectively performed after overall benefit/risk ratio considerations. All 15 reopenings were equally depicted by both techniques except one that was depicted earlier on CEMRA. Among the 9 TO at TOF MRA and NR at CEMRA at 1 year, 3 cases enlarged to NR at TOF at 4 years, most remained stable. Among the 22 cases judged NR at 1 years with both techniques, 3 cases showed enlargement at both techniques, while in other 3 cases AR was evident only at 3DCEMRA and they were not retreated. Conclusions: CEMRA superiority in depiction of intracranial aneurysms recanalization is confirmed by our data. Nevertheless a clear impact in patient management is apparently not evident. Evidence of occlusion at 3DTOF FU may not need the addition of a CEMRA study.
