 There is mild nonspecific prominence of the ventricles, especially the lateral ventricles. The sulci are within normal limits. The basal cisterns remain patent. There is no midline shift. There are few punctate and linear foci of T2/FLAIR hyperintensity left greater than right frontal white matter. The most conspicuous finding has a very linear in configuration on the coronal images. There is no diffusion abnormality. There is a small area of CSF signal intensity along the medial aspect of the left middle cranial fossa, with mild flattening of the adjacent temporal lobe parenchyma, likely representing an arachnoid cyst as there is no associated diffusion restriction. This measures 0.8 x 2.2 cm in greatest axial dimensions, x 1.5 cm CC. No pathologic extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is trace fluid within right mastoid air cells. There is no gross noncontrast abnormality involving the visualized portions of inner ear structures.
1.Dedicated IAC images were not obtained inadvertently as a separate order was not present. No gross noncontrast abnormality involving visualized portions of inner ear structures, although detailed evaluation of internal auditory canal contents and inner ear structures should be obtained with dedicated protocol. Follow-up separate order may be considered as clinically indicated.2.Scattered nonspecific punctate and linear foci of T2/FLAIR hyperintensity in the left greater than right frontal white matter. Some of the more linear areas may represent prominent perivascular spaces.3.Mild nonspecific prominence of the ventricles.4.Incidental small arachnoid cyst along the medial aspect of the left middle cranial fossa with mild localized mass effect on the mesial left temporal lobe.
