39 year old female with neurosarcoidosis. Interval change of the fourth ventricle. Shunt placement left frontal. Rest of provided clinical data is not legible. Transient alteration of awareness. Nonenhanced CT of brain:Images through posterior fossa demonstrate an enlarged fourth ventricle and no appreciable interval change since prior MRI exam.Images through supratentorial space demonstrate collapsed left lateral ventricle. This is similar to what was noted on prior MRI exam. Normal appearing right lateral ventricle and similar in size to prior MRI study.Third ventricle is small and in midline and with no interval change. Left-sided ventricular catheter traverses the left frontal lobe, enters the left frontal horn, traverses the midline and with the tip at the level of foramina of Monroe on the right. Small area of encephalomalacia in bilateral frontal lobes (right greater than left) shows no interval change since prior MRI. There is no evidence of hemorrhage, edema mass-effect or midline shift.
1.No evidence of new findings since prior MRI examination of brain.2.Dilated fourth ventricle and a small supratentorial ventricular system remains stable since prior study.
