ABSTRACT

Diagnosis: Multiple Sclerosis, Quadrantanopsia

History: 42 y.o. combat fighter pilot c/o "blind spot" - sudden onset six days ago and lasted about four hours. Previous Hx of a similar episode several years ago.

Findings: • Lateral geniculate body - abnormal signal and enhancement • Additional periventricular lesions

Ddx: • Multiple sclerosis • Lyme disease • ADEM (Acute Disseminated Encephalomyelitis) • Sarcoidosis • Vasculitis (SLE, etc.)

Dxhow: Clinical Hx and response to steroid therapy

Exam: Right inferior quadrantanopsia on formal visual field testing G6PD deficiency

No MeSH data available.


There is a lesion near the lateral geniculate body on the patient's left with contrast enhancement. Posterior (distal) to the LGB the optic radiations for the superior and inferior portions of the visual hemi-field separate - so a lesion may affect only one quarter of the field - a "quadrant- anopsia".
