Persistent headaches. Non-enhanced CT of brain:There is no evidence of intracranial hemorrhage, edema, mass effect or midline shift or hydrocephalus. There is a small foci of low-attenuation in the right basal ganglia close to CSF density on axial image 13 which may represent small old lacunar in part. This examination is otherwise unremarkable. Please correlate with history and risk factors and follow-up with an MRI.The cortical sulci, ventricular system, CSF cisterns and gray -- white matter remains otherwise within normal limits. Calvarium is intact. Visualized paranasal sinuses and mastoid air cells are unremarkable.
1.A single small focus of low-attenuation in the right basal ganglia measuring 7 times 4-mm in size with close to CSF density is suspected for an old lacunar infarct. Exam is otherwise unremarkable. Correlate with history and risk factors and follow.2.Normal calvarium, visualized paranasal sinuses and mastoid air cells.
