“Cord Sign” in Deep Cerebral Venous Thrombosis

Abstract

A 17-month-old girl presented to the emergency department (ED) with an altered sensorium and abnormal limb movements that had developed over the prior 6 h. She had a history of vomiting (non-bilious and non-projectile), lethargy, and poor feeding for the prior 7 days. Neurological examination showed exaggerated limb reflexes, however, tone and power were normal. A non-contrast head computed tomography (CT) scan (Figure 1) showed ill-defined hypodensities in both thalami, with hyperdensity in the internal cerebral vein, vein of Galen, and straight sinus, suggestive of deep cerebral venous thrombosis (DCVT).
