1

What is observed in the spleen in patients with portal hypertension?

Linear reflective channels

2

What is the splenic interface sign

Dilatation of intrasplenic
venous sinuses with increased collagen in the walls and periarterial fibrosis
- back up of flow

3

Hypersplenism

Over active spleen
- removes blood cells too early/quickly

4

What can happen with hypersplenism?

Spontaneous splenic rupture may occur in a patient if an enlarged spleen has minimal trauma or coughing fit

5

What are indications of a spleen exam? (3)

1. Mononucleosis
2. Congestion
3. Inflammatory
- rheumatologic
4. Neoplasia
5. Infiltrative
6. Hematologic

6

What is the the most common “infectious” reason for ordering an ultrasound?

Mononucleosis

7

Sarcoidosis

Is a multisystem granulomatous disease that is associated with splenomegaly

8

Mononucleosis

Is an infectious disease where patients feel tired and weak for months because it affects the immune system and causes splenomegaly

9

What are 2 complications of mononucleosis?

1. Splenic infarct
2. Rupture

10

Non-Hodgkins/Hodgkins Lymphoma

Cancer of the lymphatic system

Is Non-Hodgkins/Hodgkins Lymphoma benign or maligant?

Malignant

14

Hodgkins Disease

Abnormal cells
