title: Case report: asymmetrical development of the gyri recti presenting as a suprasellar mass: case report and description of six further cases.
abstract: Asymmetrical appearances of normal anatomical structures can sometimes mimic pathology. We present a case where asymmetry of the gyri recti was interpreted as a suprasellar mass on axial CT scanning. The true nature of the apparent abnormality was revealed by coronal magnetic resonance imaging (MRI). We also present six further cases where asymmetrical gyri recti were noted as incidental findings on coronal MRI scans. This is a common, but important, normal anatomical variant, which should not be mistaken for pathology.
