| ==Overview==
| |
|
| |
| Ultrasound may be helpful in the diagnosis of appendix tumors, appendix mucucele, and [[appendicitis]] as the most prevalent complication of appendiceal cancers.
| |
|
| |
| There are no echocardiography findings associated with appendix cancer. However, an echocardiography may be helpful in the diagnosis of complications of carcinoid tumor; If a patient develop carcinoid syndrome transthoracic echocardiography is the method of choice in the diagnosis and follow-up of carcinoid heart disease.

|
| |
| ==Ultrasound==
| |
| *There are no specific ultrasound findings associated with appendix cancer.
| |
| *Ultrasound may be helpful in the diagnosis of appendix mucucele, and [[acute appendicitis]] as the most prevalent complication of appendiceal cancers.
| |
| *The following might be presented in ultrasonographic study of the patients with appendiceal cancer:
| |
| **Dilated appendix
| |
| **Periappendiceal fluid collection
| |
| **Distinct appendix wall layers

| **[[Tricuspid regurgitation]]
| |
| **Thickening and retraction of immobile tricuspid valve leaflets
| |
| **Immobility of the pulmonary valve cusps
| |
| **Right atrium as well as right ventricle enlargement
