Prosopagnosia in the context of right handedness, left hemisphere perinatal stroke, epileptogenic cyst, and focal epilepsy: A pre-surgical case report

Abstract

Prosopagnosia, a neurological condition affecting perception and differentiation of faces, is categorized as either acquired or developmental (present since birth). Acquired cases of prosopagnosia are usually caused by right hemisphere or bilateral damage. We present a right-handed 17-year-old male with a history of focal epilepsy and a new diagnosis of prosopagnosia due to a perinatal stroke affecting the left lingual gyrus, a structure in close proximity to the fusiform face area. In addition to showing that early acquired cases of prosopagnosia may go unrecognized, this case shows that left hemisphere lesions may also affect facial recognition. It is important to screen for prosopagnosia via comprehensive neuropsychological evaluation in patients with lesions proximal to the fusiform face area.
