Tuberous sclerosis [759.5] / Benign neoplasm of kidney, except pelvis [223.0], Reason for Study: ^Reason: evaluate changes in renal angiomyolipomas s/p embolization History: tuberous sclerosis Multiple bihemispheric cortical high signal intensity lesions involving left superior frontal gyrus, left parietal lobe superior and inferior parietal lobule, left lateral orbital gyrus, left temporo-occipital gyri, right superior frontal gyrus, right inferior parietal lobule, right insular, right temporo-occipital gyri and right lateral orbital gyrus indicate cortical tubers, and they do not show any significant interval change in terms of size and MR characteristics since prior scan.High signal intensity lesions on the subcortical white matter on the right posterior temporal lobe, left trigone area, left lateral orbital gyrus subcortical white matter, no change since prior scan.Enhancing lesions on the left lateral ventricle occipital horn, left side foramen of Monroe and right lateral ventricle occipital horn area indicating subependymal giant cell astrocytomas do not show any significant interval change since prior scan in terms of size and MR characteristics.There are also various sized subependymal nodular lesions on bilateral lateral ventricles indicating subependymal hamartomas appear to be stable in terms of size, number and MR characteristics since prior exam.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No interval change of above described cortical tubers, white matter abnormal signal intensities, subependymal hamartomas, and subependymal giant cell astrocytomas since prior scan.
