Male, 74 years old, with history of petrous apex lesion, sixth nerve palsy. A lobular T1/T2 hyperintense lesion involving the right petrous apex with effacement of the adjacent Meckel's cave has not significantly changed in size or morphology measuring approximately 24 x 17 mm in the axial plane.Likewise, a small enhancing, T1 hypointense lesion occupying the right aspect of the clivus is unchanged in size and morphology measuring 11 x 8 mm in the axial plane.A few scattered small nonspecific white matter T2 hyperintense lesions are evident in the cerebral hemispheres. No parenchymal edema or mass effect is detected. No evidence of significant intracranial hemorrhage or any abnormal extra-axial fluid is seen. Ventricles are stable and normal in size. On postcontrast imaging, no pathologic parenchymal or leptomeningeal enhancement is detected.
1.No significant interval change in the size or morphology of a T1/T2 hyperintense lesion involving the right petrous apex which may represent a cholesterol granuloma.2.No significant interval change in size or morphology of a nonspecific T1 hypointense enhancing region involving the right clivus.3.No new or acute intracranial abnormalities are detected.
