Clinical question: Intraventricular brain cyst, evaluate for change/size, one year follow up. Signs and symptoms: As above. Nonenhanced brain MRI:Unremarkable diffusion weighted series.Examination demonstrate evidence of acute or new finding since prior exam. Mildly expansile trigone of right lateral ventricle at the site of a previously fenestrated intraventricular cyst remains identical in size and extent to prior exams.Right posterior temporal approach for fenestration of the cyst remains stable and with revisualization of a linear encephalomalacia along the surgical approach similar to prior exam.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination otherwise and stable since prior study. Normal visualization of signal voids of major intracranial arterial branches. Normal signal intensity of the intracranial venous sinuses.Unremarkable calvarium, orbits, mild chronic sinus disease and unremarkable mastoid air cells and middle ear cavities.
1.No acute or new finding since prior study.2.No detectable interval expansion of previously fenestrated right intraventricular cyst.3.Stable linear encephalomalacia along the course of surgical approach in the right posterior temporal.4.Stable and unremarkable brain MRI otherwise.
