A left posterior temporal approach ventriculostomy catheter appears stable in overall position. There remains focal fluid density along the portion of the catheter in the scalp just distal to the reservoir, with focal redundancy of the catheter at this level partially visualized. There has been interval slight decreased caliber of the lateral and third ventricles. For example, the third ventricle now measures 7 mm transverse as compared to previous 8 mm, while a measurement across the anterior body of the lateral ventricles is now 3.3 cm as compared to previous 3.5 cm. The fourth ventricle remains small in size. The septum pellucidum appears absent. There is a colpocephalic appearance to the streak aspect of the lateral ventricles which may relate to callosal dysgenesis. The anterior aspect of the corpus callosum appears to be present. There is no midline shift or mass effect. There is no intracranial hemorrhage. There are a few dystrophic calcifications along the left tentorium. There are no areas of abnormal attenuation. There is no extraaxial fluid collection. The visualized portions of the paranasal sinuses and mastoids or middle ears are grossly clear. Cerebellar tonsils again extend caudal to the level the foramen magnum by approximately 8-9 mm, with crowding at this level.
