case_images: Axial sagittal computed tomography with brain (a and b) and bone (c and d) windows showing a small cutaneous mass over the previous craniotomy site with an underlying bony erosion and a small right frontal intracranial component (2016 study).

case_images: Computed tomography (CT) showed midline and right frontal recurrence of intracranial meningioma with a cutaneous component eroding the craniotomy flap and extending to the scalp [Figure 1].
case_images: Front and top view of the patient's head showing the external appearance of the cutaneous meningioma with large lateral extension and disfigurement. There are multiple scalp ulcerations.

case_images: Six months later, he presented to our emergency department with a massive face and bifrontal cutaneous mass that displaced his right eye inferiorly and laterally [Figure 2].
case_images: (a-f) Axial and sagittal computed tomography in 2018 showing massive enlargement of the cutaneous component extending to the face, right ethmoidal sinus, and right orbit.

case_images: CT scan and MRI showed significant involvement of the bilateral frontal, right ethmoidal, right periorbital bone, and cribriform plate bone with large intracranial component causing a significant mass effect of the bifrontal lobes with extensive vasogenic edema, likely due to cerebral invasion [Figures 3-6].
case_images: (a-c) Axial magnetic resonance imaging with contrast from the vertex till the basal ganglia showing significant intracranial component with bilateral frontal dural attachment and severe mass effect on the frontal lobes and lateral ventricles bilaterally. The right superomedial invasion of the orbital cavity is appreciated (d).

case_images: CT scan and MRI showed significant involvement of the bilateral frontal, right ethmoidal, right periorbital bone, and cribriform plate bone with large intracranial component causing a significant mass effect of the bifrontal lobes with extensive vasogenic edema, likely due to cerebral invasion [Figures 3-6].
case_images: (a-c) Sagittal magnetic resonance imaging with contrast showing the anterior and inferior extent of the cutaneous component with the involvement of the face and right orbit.

case_images: CT scan and MRI showed significant involvement of the bilateral frontal, right ethmoidal, right periorbital bone, and cribriform plate bone with large intracranial component causing a significant mass effect of the bifrontal lobes with extensive vasogenic edema, likely due to cerebral invasion [Figures 3-6].
case_images: Coronal magnetic resonance imaging with contrast showing the lateral extent of the cutaneous component (a). Magnetic resonance venography showing complete occlusion of the anterior and middle thirds of the superior sagittal sinus (b). Axial T2 image showing the vasogenic edema surrounding the intracranial component (c).
