Which groove is associated with subependymal hemorrhage in neonates?

Subependymal (germinal matrix) hemorrhage in neonates happens where the germinal matrix is located—just beneath the ependyma near the caudothalamic groove. This groove lies at the border between the caudate nucleus and the thalamus and marks the vulnerable territory of the fragile, immature vessels of the germinal matrix. When bleeding occurs, it characteristically appears along this caudothalamic groove on neonatal ultrasound and can extend into the ventricular system. Other grooves don’t correspond to the germinal matrix location, so they’re not typical sites for subependymal hemorrhage. The caudothalamic groove is the classic landmark for detecting this condition.
