Presentation A potential kidney donor was detected to have asymptomatic hypercalcemia. An ultrasound of the neck was performed.
Caption: Transverse scan of the left neck
Description: The left thyroid appears normal. At least 2 oval solid appearing hypoechoic masses are seen [labeled as 1 and 2], posterior to the left lobe of the thyroid and just medial to the carotid artery, [labeled as c].
Caption: Sagittal scan of the left neck
Description: The larger and more medially located oval hypoechoic mass is seen here posterior to the left lobe of the thyroid gland. Note the more brightly reflective capsule seperating it from the thyroid.
Caption: Transverse color Doppler images of the left neck
Description: The location of the two masses in relation to the thyroid gland and medial to the carotid artery is demonstrated.
Caption: Power Doppler image
Description: The more medial hypoechoic mass is seen here. It appears to derive its blood supply from a branch of the thyroid vessel.
