Abstract: | The spleen is generally not considered a challenge to the radiologist. Most often it poses a problem by anomalies or an irregular
but normal contrast enhancement; however, a variety of inflammatory, infectious and neoplastic diseases may involve the spleen.
CT and ultrasonography are screening modalities for the spleen. For problem solving, MR imaging can be helpful, especially
due to its free choice of the imaging plane and because of the high resolution in contrast MR imaging. Splenic angiography
as a diagnostic tool has generally been replaced by CT, ultrasound, or MR and is now used as an interventional method, e.
g., in non-surgical management of patients with chronic idiopathic thrombocytopenia or in patients with splenic trauma. This
article reviews the radiology of the spleen, including anatomy, embryology, splenomegaly, splenic injury, infarction, cysts,
tumors, abscesses, sarcoidosis, and AIDS. Knowledge about the use of different imaging modalities and underlying gross and
microscopic pathologic features leads to a better understanding of the radiologic findings.
