Sectoranopia After Head Trauma

Abstract

Sectoranopia is a homonymous, horizontally oriented, wedge-shaped visual field defect typically associated with lateral geniculate body (LGB) lesions, [1-3] but recent reports challenge the diagnostic location specificity of sectoranopia by demonstrating causal retrogeniculate lesions [4-6]. Due to its size and location, neuroradiologic demonstration of the LGB was difficult until the development of MRI [7]. We followed a patient with sectoranopia as a consequence of severe head trauma. MRI revealed an isolated contralateral LGB lesion. Case report. On July 22, 1993, a previously healthy 25-year-old man was involved in a car accident and suffered frontal and facial traumatism. He presented with multiple facial fractures (Le Fort II and left hemi-Le Fort I fracture types) necessitating hospitalization and multiple maxillofacial surgeries. Left ocular contusion …
