46-year-old female with right frontal mass a slight soft tissue/abscess. Rule out bleed. Examination demonstrates an irregularly shaped bony defect of right frontal bone. Soft tissue density mass externally over this bony defect is present. Very minimal epidural thickening also within the intracranial space at this level is present. There is no evidence of edema, mass effect or midline shift secondary to this finding. Further evaluation with an MRI is recommended for possibility of tumor or an infectious process. No additional bony defect is detected. Paranasal sinuses and mastoid air cells are unremarkable. Images through intracranial space demonstrate no definitive evidence of any additional abnormality. No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus is present.
1.Irregular bony defect with large extracranial soft tissue component that is concerning for tumor or an abscess and should be further evaluated with dedicated MRI.2.Unremarkable CT examination of intracranial space.
