Occasionally, cows are observed to leak milk continuously. Diagnosis is by needle aspiration. They can range from diffuse, tightly adherent lesions to highly mobile discrete lesions that float throughout the gland cistern. Complex teat obstructions or obstructions in valuable animals may require diagnostic imaging such as ultrasonography, contrast radiography, or theloscopy endoscopy. Acquired teat obstructions are usually the result of proliferation of granulation tissue after the occurrence of an observed or unobserved teat injury.

Udder swelling from edema or trauma is a potential underlying cause. Teat obstructions are usually recognized when they interfere with milk flow. All injuries to, or surgical procedures on, the teat should be handled carefully to prevent infection.
