Antenatal diagnosis of the common variant (associated with tetralogy of Fallot) of APVS is easy because of its typical features of a dilated main pulmonary and branch arteries and color Doppler detection of severe stenosis and insufficiency of the functionally absent pulmonary valve. However, the second variant of APVS can have various findings, which can make a specific diagnosis difficult.

Evolution in ultrasound technology leads to birth of high frequency, high resolution linear transducers which in turn revolutionized the imaging of superficial structures. The majority of cases presenting to clinician in day-to-day practice as facial lumps or neck lump could be evaluated using ultrasound and help in imaging of salivary gland lesions. The age of the clinical presentation and morphological characteristics of lesions on ultrasound helped us in making confident diagnosis which was correlated on fine needle aspiration cytology/histopathology studies.
