Preoperative computed tomography (CT) and magnetic resonance imaging (MRI). CT showing a left frontal tumor and left hyper dense sign (arrowhead) (a). Diffusion-weighted image on MRI showing an acute cerebral infarction (b), and magnetic resonance angiography showing a left middle cerebral artery occlusion (c). Fluid-attenuated inversion recovery image on MRI showing enlargement of tumor and peritumoral edema 10 years prior (d), 7 years prior (e), 5 years prior (f) to the onset, and at the onset of cerebral infarction (g).

Magnetic resonance imaging (MRI) revealed an acute cerebral infarction in the left corona radiata and a left middle cerebral artery occlusion [Figures 1a-c]. Asymptomatic left frontal meningioma with peritumoral edema was also observed [Figures 1a and b]. The tumor size and edema were remarkably increased [Figures 1dg].
Digital subtraction angiography (DSA) of the pre- and post-mechanical thrombectomy. Pre-DSA showing a left middle cerebral artery occlusion (a). Post-DSA showing the recanalization of the middle cerebral artery (b) and the tumor staining of left frontal tumor with a pial supply in the posterior part of the tumor (arrow head) (c).

She underwent urgent mechanical thrombectomy and recanalization was achieved [Figures 2a-c].
Postoperative day 26 computed tomography (CT) showing intratumoral hemorrhage (a). Postoperative day 48 CT showing intra and peritumoral hemorrhage (b). Gadolinium-enhanced T1-weighted image on MRI showing a diffuse enhanced tumor with an intratumoral hemorrhage and peritumoral hemorrhage compressing the surrounding brain (c).

Computed tomography (CT) revealed an asymptomatic intratumoral hemorrhage at postoperative day 26 [Figure 3a]. CT and MRI revealed an intra-and peritumoral hemorrhage with compression of the surrounding brain [Figures 3b and c].
Post tumor resection T1-weighted (a) and Gadolinium-enhanced T1-weighted magnetic resonance imaging (b) showing gross total resection of the tumor.
