From: Delayed extensive brain edema caused by the growth of a giant basilar apex aneurysm treated with basilar artery obliteration: a case report

Fig. 5

Follow-up magnetic resonance imaging (MRI) showed almost complete thrombosis of the lumen of the aneurysm and progressive reduction of the aneurysmal external contour. a, e, i, m: Sagittal T1-weighted images (T1WI) showed resolution of the intramural hematoma, no new intraluminal fresh thrombus and progressive decrease in the maximum external diameter of the aneurysm, thus alleviating brainstem compression. b, f, j, n: Axial fluid-attenuated inversion recovery (FLAIR) and/or T2-weighted images (T2WI) showed progressive resolution of brain edema. c, g, k, o: Sagittal, coronal and axial maximum intensity projection (MIP) reconstructions of magnetic resonance angiography (MRA) showed no filling of the aneurysm sac, and filling of the upper basilar apex via both posterior communicating arteries (PCoAs). d, h, l, p: Sagittal, coronal and axial MIP reconstructions of contrast enhanced 3-dimensional time of flight (3D-TOF). Although no filling of the aneurysm was found, a marked gadolinium enhancement is noted around the top of the basilar artery, representing the old intraluminal thrombus. The maximum external diameter of gadolinium enhancement decreased over the follow-up period (red arrows)
