Anton syndrome as the first presenting sign of diabetes mellitus in a healthy 50-year-old male: A case report

Anton-Babinski syndrome is a rare condition associated with cortical blindness (CB), typically following an occipital lobe insult. It involves visual function impairments where patients, despite being blind, deny their visual loss and may confabulate. CB results from lesions in the bilateral occipital lobes affecting the geniculocalcarine pathways, with the anterior visual pathways remaining intact. Complete CB is rarer than partial forms. We present a case of a 50-year-old healthy male diagnosed with Anton syndrome who presented with a unilateral headache for the past 4 days and a fever for the past 20 days. He gave a treatment history for pulmonary tuberculosis at the age of 13. The anterior and posterior segments, blood, and Cerebrospinal fluid (CSF) analyses were within normal limits. Magnetic resonance imaging (MRI) angiogram shows bilateral posterior cerebral artery stroke, and MRI brain showed bilateral occipital lobe infarcts due to Cerebrovascular accident (CVA). Here, we discuss this patient’s possible differential diagnosis and management strategies with a literature review.
