Management Strategy for a Patient with Coexistence of Meningioma and Paraophthalmic Aneurysm.

The coexistence of intracerebral aneurysm and meningioma is a rare occurrence. There is no consensus about the treatment options. We aim to present a case of a 61-year female admitted to this clinic with persistent headache and loss of vision in both eyes, especially on the left. Radiological images demonstrated a para-ophthalmic saccular aneurysm coexisting with an extra-axial homogenously enhancing mass in the right cavernous sinus, which was possibly a meningioma. A flow diverting stent, following the coil embolisation of the aneurysm, was placed. Then the patient underwent stereotactic radiosurgery for the cavernous sinus meningioma. Diagnosis and treatment of such pathologies are easily achieved with the technological advancements of imaging techniques. The hypothesis of increased hemodynamic pressures, due to meningioma causing intracranial aneurysms, may explain this coexistence. Endovascular surgery, followed by stereotactic radiosurgery, may be a reliable approach for a patient with coexistent meningioma and aneurysm. Key Words: Meningioma, Aneurysm, Cavernous sinus.
