Prosopometamorphopsia secondary to a left splenium of the corpus callosum infarct

Description 

A 67-year-old right-handed woman with a medical history of coronary artery disease, hyperlipidaemia, hypertension and diabetes mellitus presented with seeing peoples' faces distorted on the left side. When she saw faces in person or watched images of people on television, she noted the left eye on faces appeared to be moving to the side and upwards. She did not see any distortion when looking at her own face in a mirror or when looking at photographs of faces. She had no difficulty recognising faces and nothing other than faces appeared distorted to her. Her neurological examination was normal. Her ophthalmological examination was also unremarkable. Brain MRI performed 2 months after symptom development showed a subacute infarct in the left aspect of the splenium of the corpus callosum (figure 1A).
