Abstract

Idiopathic brain herniation is a rare condition. We believe that this is the first reported case of idiopathic herniation of the lingual gyrus. The case involves a 57-year-old woman presenting with frontal headache without overt visual symptoms. Magnetic resonance imaging (MRI) revealed an idiopathic herniation of the lingual gyrus of the occipital lobe extending into the quadrigeminal cistern. No other adjacent intracranial abnormalities were observed. Although some conditions may be considered in the differential diagnosis, accurate diagnosis of idiopathic brain herniation in medical practice can prevent unnecessary additional imaging procedures and invasive open biopsy in patients with typical imaging findings.

  Fig. 1 Magnetic resonance images from a 57-year-old woman with idiopathic lingual gyrus herniation. The axial and coronal 3D T1-weighted MPRAGE images (a, b) with contrast administration show a focal bulging contour (indicated by arrows) continuous with the lingual gyrus of the right occipital lobe protruding into the quadrigeminal cistern. No definite dural defect was seen in the adjacent herniated gyrus (indicated by arrows) on axial or coronal 3D T1-weighted MPRAGE images or on axial T2-weighted FLAIR images (a–c).
