What can an ultrasound of the spleen show?
RESULTS: We describe the ultrasonic features of various splenic lesions such as accessory spleen, splenomegaly, cysts, cavernous hemangiomas, lymphomas, abscesses, metastatic tumors, splenic infarctions, hematomas, and rupture, based on traditional gray-scale and color Doppler sonography.
What are the characteristics of splenomegaly on abdominal examination?
The most common complaint in patients with splenomegaly is mild, vague, abdominal discomfort. Patients may also experience pain,which may be referred to the left shoulder. Increased abdominal girth is less common. Early satiety from gastric displacement occurs with massive splenomegaly.
What does spleen look like on ultrasound?
On sonography, the spleen is crescent shaped. Its outer convexity is smooth, whereas the inner margin may be indented or nodulous. Its echo structure is homogeneous and only slightly more echogenic than healthy liver tissue and markedly hyperechoic compared to kidney tissue.
What are the differential diagnosis of splenomegaly?
megaloblastic anemia (rare) infection, e.g. viral (infectious mononucleosis, hepatitis), bacterial (infective endocarditis) CTD/ vasculitis, e.g. SLE, rheumatoid arthritis, PAN. infiltration, e.g. amyloidosis, sarcoidosis.
Can ultrasound detect spleen problems?
Ultrasound scanning is reliable, safe, quick and non-invasive, allowing an abnormal spleen to be detected with a high coefficient of sensitivity and specificity.
What is splenic ultrasound?
Ultrasound (US) is a very useful means of noninvasively examining the spleen. Imaging is generally achieved via an intercostal approach using gray scale US supplemented by color flow to assess vasculature. Normal spleen appears uniform with vessels radiating and converging at the hilum.
How would you describe splenomegaly?
Splenomegaly is an enlargement of the spleen. The spleen usually lies in the left upper quadrant (LUQ) of the human abdomen.
How do you examine splenomegaly?
Palpation for splenic enlargement should begin with the patient supine and with knees flexed. Using the right hand, the examiner should begin well below the left costal margin and feel gently but firmly for the splenic edge by pushing down, then cephalad, then releasing (Figure 150.1).
What are spots on the spleen?
In the immunocompromised patient, multiple small splenic lesions usually represent disseminated fungal disease and microabscesses. The spleen is a relatively rare site for metastatic disease; patients with metastatic lesions in the spleen usually have disease in other sites as well.
Can an enlarged spleen be seen on ultrasound?
Usually doctors can feel an enlarged spleen, but ultrasonography and other imaging tests may be used to determine how large the spleen is.
How do you read an abdominal ultrasound?
As a general rule, in the transversal plane:
- The top of the ultrasound image is the anterior (ventral) side and the bottom is the posterior (dorsal) side.
- Left on the image is actually right and vice versa. The body is seen from below as it were (as in a transversal section of a CT scan).
