A-62 Case of Gerstmann’s Syndrome Due to Brain Tumor of Unknown Etiology

Abstract

Abstract Objective Gerstmann’s syndrome is a rare neurological condition that is characterized by agraphia, acalculia, finger agnosia, and right–left confusion. Gerstmann’s syndrome most commonly occurs due to stroke in parietal region of the brain. This case demonstrates the clinical presentation of Gerstmann’s syndrome in a patient due to a brain tumor in the parietal lobe. Method The patient is a 50-year-old, right-handed, Hispanic male with 16 years of education who reported memory changes over the last 10 months. His medical history is notable for two brain tumors of unknown etiology which have been present for 10 months. He has completed multiple biopsies and magnetic resonance imaging prior to his neuropsychological evaluation. Initial scans showed two tumors, one in the right medial occipital parietal lobe and one in the left parietal extending into the corpus callosum. The right medial occipital parietal lobe tumor has not been visualized for the past six months. Results His neurocognitive profile was characterized by impairments in verbal memory (both stories and word list), arithmetic, semantic fluency, and executive functioning. Across memory measures, he performed in the borderline to impaired range, and did not benefit from recognition items. Arithmetic performance was also in the borderline range and did not show improvement with additional time. Conclusions This case demonstrates the classical findings of Gerstmann’s syndrome with additional neurocognitive impairments in the areas of memory and executive functioning. This case is also unique in that the lesions of the parietal lobe are due to brain tumor with unknown etiology.
