| Cortical tubers, or benign potato-like growths, appear along the gyri and sulci in the brain. |
| The occipital lobes form the posterior portion of the superior surface behind the parieto-occipital sulci. |
| The development of lobation in later growth stages is mainly expressed in the widening and deepening of sulci. |
| After their excision, the insula appears as a triangular eminence that is marked by a number of sulci and gyri. |
| Common findings on brain imaging include enlarged ventricles, widened cortical sulci, and cerebral, cerebellar, or brain stem atrophy. |
| A second computed tomographic scan showed effacement of the temporal sulci and gyri, which was believed to be secondary to cerebral edema. |
