12-year-old male with visual changes and headaches. No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus is detected. Cortical sulci, ventricular system and all CSF cisterns are within normal limits. Paucity of cortical sulci and small ventricular system although normal for patient's stated age it could also represent findings of pseudotumor cerebri.There is suggestion of some crowding at the level of foramen magnum which although may be due to slice positioning, possibility of slight ectopia of cerebellar tonsils cannot be ruled out. Multiple prior CT examination of this patient's back to 2004 were all reviewed. Similar findings are also noted on all prior studies. An MRI examination of brain is recommended for further and better evaluation to explain patient's repetitive visits for similar clinical symptoms.Bony density of calvarium, pneumatization of paranasal sinuses, middle ear cavities and mastoid air cells are within normal limits.
Stable examination since prior studies. The common follow-up with an MRI examination. Please see above comments.
