Diagnosis is usually made based on history and physical examination. The role of imaging in Mondor's disease is to identify the intravascular thrombus. In case of diagnostic uncertainty, Grey scale and Doppler ultrasound can be useful to detect the extent of thrombosis demonstrating echogenic material within venous lumen, vessel incompressibility and absence of flow, as well as painful selective pressure. The use of Magnetic Resonance imaging is controversial and not used routinely.
