Female, 51 years old, with cerebral aneurysm. Assess for aneurysm stability. A 14 x 11 mm mildly T2 hyperintense lesion within the left aspect of pons has not significantly changed in size accounting for differences in imaging technique.A few scattered nonspecific small foci of T2 hyperintensity within the cerebral white matter are also not significantly changed from prior. No evidence of restricted diffusion is seen. No parenchymal edema or mass effect is detected.There is no finding to suggest intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricular system is patent and normal in size.A 4 x 3 mm medially directed aneurysm arising from the anterior genu of the left ICA has not significant changed in size or shape. No new aneurysms are suspected. No significant intracranial vascular stenosis is seen.
1.Stable nonspecific T2 hyperintense lesion within the left aspect of the pons.2.No significant interval change in size or morphology of a 4 x 3 mm aneurysm arising in the vicinity of the left superior hypophyseal artery.
