The CT and MRI showed a 20 mm middle cerebral artery (MCA) bifurcation aneurysm immediately below the cavernous angioma which measured 50 mm (see Figure 1A, Figure 1B, Figure 2A, Figure 2B, Figure 3A, Figure 3B, Figure 4 and legends for description), findings which were supported by a catheter angiogram (see Figure 5).

The CT and MRI showed a 20 mm middle cerebral artery (MCA) bifurcation aneurysm immediately below the cavernous angioma which measured 50 mm (see Figure 1A, Figure 1B, Figure 2A, Figure 2B, Figure 3A, Figure 3B, Figure 4 and legends for description), findings which were supported by a catheter angiogram (see Figure 5).
43-year-old woman with worsening left-sided headaches. Axial T2W images demonstrate MCA aneurysm which was originally mistaken for a "tumour nodule."

The CT and MRI showed a 20 mm middle cerebral artery (MCA) bifurcation aneurysm immediately below the cavernous angioma which measured 50 mm (see Figure 1A, Figure 1B, Figure 2A, Figure 2B, Figure 3A, Figure 3B, Figure 4 and legends for description), findings which were supported by a catheter angiogram (see Figure 5).
43-year-old woman with worsening left-sided headaches. Axial T2W images demonstrate typical features of a cavernous angioma with a mixed signal core, complete haemosiderin rim, and blooming susceptibility effect.

The CT and MRI showed a 20 mm middle cerebral artery (MCA) bifurcation aneurysm immediately below the cavernous angioma which measured 50 mm (see Figure 1A, Figure 1B, Figure 2A, Figure 2B, Figure 3A, Figure 3B, Figure 4 and legends for description), findings which were supported by a catheter angiogram (see Figure 5).
43-year-old woman with worsening left-sided headaches. Axial T1W pre-contrast (gradient echo) MRI. Note the marked heterogeneity within the cavernous angioma, the high signal change which is consistent with blood products.
