title: Massive primary hemorrhage during tonsillectomy from a large venous varicosity.
abstract: The internal jugular vein is derived embryologically from the anterior cardinal veins. Developmental abnormalities may result in a cavernous venous varicosity, which may be the cause of massive primary hemorrhage during tonsillectomy. An index of suspicion is required for diagnosis, which may be confirmed by retrograde venography techniques.
