Sarkoidose bei einem 36jährigen Mann. Befall von Leber und Milz sowie der Lunge. Die Computertomographie axial zeigt multiple hypodense Herde, die primär an ein Malignom denken ließen, zumal die Befunde in der PET-CT stark stoffwechselaktiv waren.

Computed
tomography of the spleen: how to interpret the hypodense lesion. Transverse contrast-enhanced CT image acquired during the portal-venous phase in a 38-year-old woman illustrating a lymphangioma of the spleen. Note the lesion’s septations (arrow) that may enhance slightly after the administration of intravenous contrast material and homogeneous water-like content in the absence of solid components. The most important differential diagnosis to consider in this case would be a hydatid (echinococcal) cyst

There are a number of splenic lesions and anomalies:

Congenital anomalies
Mass lesions
Benign mass lesions
Indeterminate mass lesions
Malignant mass lesions
Diffuse infiltrative processes

These usually manifest as splenomegaly. Some can present as distinct lesions (e.g. granulomas).

Multifocal splenic lesions
Other abnormalities
