42-year-old female with no significant past medical history presenting with headache (left-sided frontal) and nausea. Please evaluate for sinus inflammation. There is no evidence of acute findings including intracranial hemorrhage, edema or midline shift. A left frontal hypodense mass lesion appears extra-axial and is associated with adjacent bony remodeling. There is no evidence of mass effect on the adjacent cerebral cortex. It is of unclear etiology and an MRI is recommended for further evaluation. Prominence of the sulci and ventricles indicates diffuse parenchymal volume loss especially considering the patient's age.The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
