Headaches No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus. Cortical sulci, ventricular system and all CSF cisterns as well as gray/white matter differentiation remains within normal.Limited real paranasal sinuses, mastoid air cells and middle ear cavities are unremarkable.Calvarium is intact. Small densely calcified lesion along the inner table of the skull in the right pterion with extension inferiorly along the greater wing of sphenoid on the right is noted there is a lucent line separating this lesion from the inner table of the skull which may represent the dura. The finding may not present heavily calcified dural (dural plaque) however possibility of heavily calcified meningioma cannot be ruled out. This lesion can be further evaluated with a dedicated MRI examination of brain with contrast. I detect no soft tissue component with this finding which is best appreciated on bone density images 5 through 12.
1.Negative CT of brain parenchyma.2.Thin densely calcified extra-axial dural based lesion at the level of right pterion may represent a dural plaque or a heavy calcified meningioma. Please see above comments. Follow-up with a dedicated MRI is recommended.
