Hemorrhagic Cyst Presenting as a Goiter

A large mostly hypoechoic mass expands the left lobe of the thyroid on the ultrasound of this 54 year female who presents with an enlarged thyroid gland. The left lobe is filled with low level echoes and contains multiple thin septal echogenic walls (maroon). The mass appears to displace and compress normal soft tissues of the neck (pink) anteriorly. Doppler showed no flow. The mass occupies the entire left lobe and measures 5.8cms in craniocaudad span and by 4.2 cms transversely The diagnosis in this patient is a hemorrhagic cyst causing a goiter.
