 Crax rubra sign.Illustrated non-contrast CT brain image sagittal view of a right-sided intraparenchymal hematoma matching the transparent sketch of Crax rubra bird. The head crest fans out the lateral ventricle, the eye is precisely situated in the interthalamic adhesion, and the bird’s peak spans the third ventricle from every angle. The word “rubra” means red in Latin which conveniently describes the blood-filled cerebrospinal fluid (CSF) spaces in intraventricular hemorrhage (IVH).
