title: Complete diphallia, imperforate ani (type 2 atresia ani), and an accessory scrotum in a 5-day-old calf.
abstract: A 5-day-old Angus calf was submitted to the necropsy service at the University of Kentucky Livestock Disease Diagnostic Center. At birth, the calf was noted to have 2 scrota. Five days post-calving the calf developed severe tenesmus and an umbilical infection. Clinical examination revealed atresia ani. At necropsy, complete diphallus, imperforate ani (type 2 atresia ani), and remnants of 2 scrota were identified. This report describes the gross pathologic appearance of a rare case of complete diphallia, imperforate ani (type 2 atresia ani), and an accessory scrotum in a 5-day-old calf.
