Magnetic Resonance Imaging in Internal Carotid Artery Agenesis with Computed Tomography and Angiographic Correlation

AbstractObjective:This study aimed to determine whether magnetic resonance imaging has a role in the evaluation of the sphenoid sinus and internal carotid artery. In addition, we aimed to establish reference measurements for the minimal distance between the internal carotid arteries.Method:The sphenoid sinuses and neighbouring internal carotid arteries of 90 patients were evaluated using sagittal T1-weighted and axial and coronal T2-weighted magnetic resonance images.Results:Sphenoid sinus pneumatisation was categorised as occipitosphenoidal (0 per cent), conchal (3.3 per cent), presellar (14.4 per cent) or sellar (82.2 per cent). The internal carotid artery protruded into the sphenoid sinus in 32.8 per cent, with a septum in 9.4 per cent. The incidence of sellar-type sphenoid sinus pneumatisation was higher in patients with protrusion of the internal carotid artery into the sphenoid sinus (p < 0.001). The incidence of presellar pneumatisation was higher in patients without internal carotid artery protrusion (p < 0.001). The minimal distance between the internal carotid arteries varied between 9.04 and 24.26 mm (mean, 15.94 mm).Conclusion:Magnetic resonance imaging can provide useful information about the sphenoid sinus and internal carotid artery, prior to endoscopic sphenoidotomy and trans-sphenoidal hypophysectomy.

We used fluoroscopic guidance and over-the-wire techniques to superselectively place a microcatheter into a branch of the MCA of three macaques and MRI bolus tracking techniques to measure perfusion within the selected brain region. Such techniques are likely to be useful in the assessment and treatment of ischemic infarction, cerebral vasospasm, and monitoring local delivery of drugs into the brain.

Background: Cerebral amyloid angiopathy–related inflammation is a rare condition with approximately 100 reported cases. Its clinical manifestations are varied. We report here a novel presentation of this disease. Case presentation: A 61-year-old Caucasian man presented with rapidly progressive paralysis of the IX, X, XI and XII right cranial nerves associated with right central facial nerve palsy. Brain computed tomography angiography and cerebral catheter angiography found a focal fusiform enlargement of the distal cervical portion of the right internal carotid artery, related to a pseudo-aneurysm suggesting an evolution of a dissection and intra-cranial vessel dysplasia. Brain magnetic resonance imaging showed multiple asymmetrical subcortical regions of hyperintensity on T2 fluid-attenuated inversion recovery sequences. Punctiform cortical hyposignals on T2-weighted gradient echo magnetic resonance imaging sequences were mostly congruent with the white matter hyperintensities. There was a decreased cerebral perfusion at the frontal hyperintense fluid-attenuated inversion recovery region. Spectrometry identified a lactate–lipid peak. A brain biopsy showed intravascular amyloid deposits. Corticosteroid therapy was initiated, leading to a dramatic improvement of both clinical condition and magnetic resonance imaging brain lesions. Conclusion: This case report suggests that extra-cranial vasculitis and dysplasia can exceptionally be found in patients satisfying cerebral amyloid angiopathy–related inflammation criteria.
