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.

A 73-year-old woman developed visual disturbances in the right side of the visual fields along with headache. A neurological examination showed right upper quadrantanopsia and right hemiachromatopsia. She reported that she could only see in shades of gray in the right hemifield. She also had difficulties in recognizing and naming the colors of objects presented in the right hemifield. A color-sorting test revealed generalized impairments involving all color axes. A brain MRI showed acute infarction in the left fusiform and lingual gyri.
