Clinical question : evaluate for bleed. Signs and symptoms: Headaches. Nonenhanced head CT:No evidence of intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus.The cortical sulci, ventricular system, CSF cisterns and gray -- white matter differentiation is within normal.Calvarium demonstrate a sclerotic lesion measuring 15 times 7-mm in size in the diploic space are right parietal bone. There is no erosive changes of outer or the inner table of the skull. There is no associated soft tissue abnormality with this finding and the scalp or in the epidural space. A second similar lesion is noted in the left parietal bone measuring 7 times 10-mm in size. A questionable low density lesion of calvarium in the left parietal bone is also suspected. Recommend correlation with history and follow-up with an MRI exam to exclude metastatic lesions.Visualized orbits, paranasal sinuses and mastoid air cells are unremarkable.
1.No evidence of intracranial abnormality.2.Two small focus of sclerotic bony changes of calvarium may represent bony islands. Less likely possibility of sclerotic metastatic disease cannot be ruled out. A questionable left parietal lucent lesion is also noted measuring 7 times 7-mm in size which could represent a mass. Recommend correlation with history and follow-up with an MRI exam.
