text: Ultrasound may be helpful in the diagnosis of<unk><unk> . Findings on abdominal ultrasound suggestive of<unk><unk>  include enlarged lymph nodes, hepatosplenomegaly, and ascites. Findings on extremity ultrasound include thrombosis.
  The role of abdominal ultrasound is to facilitate assessment of the spleen and liver. Patients with various subtypes of<unk><unk> s frequently have enlarged spleens. This is especially true in the primary myelofibrosis subtype of<unk>  allows for quantitative assessment of the spleen size. It can also detect liver enlargement, or hepatomegaly. Abdominal fluid such as ascites can also be detected.
  Lower extremity ultrasound is particularly useful in patients who are suspected of having deep vein thrombosis, which is commonly found in patients with polycythemia vera. Ultrasonography of the deep veins is indicated for patients with<unk><unk>  who develop leg swelling, erythema, or pain.
  In rare cases,<unk><unk>  can result in upper extremity thrombosis. Upper extremity ultrasonography can help with diagnosis of an upper extremity deep vein thrombosis.
