ABSTRACT
For masses of the spleen, which are mostly benign, accessory spleens, cysts and hemangiomas should be radiologically described; however, if confirmed further follow-up control is unnecessary. In the case of disseminated small masses, chronic inflammation and granulomatous diseases, such as tuberculosis and sarcoidosis should be considered in the differential diagnostics. Solid masses in the kidneys should always be further clarified, with the exception of a fat-rich angiomyolipoma. For cystic masses of the kidneys, the modified Bosniak classification for computed tomography or magnetic resonance imaging should be used. Masses of the adrenal glands greater than 10mm in size should be clarified further as well as those where fat is not detected, independent of the size and evidence of malignancy.

Incidentalomas of the parenchymal organs of the abdomen, i.e. radiological findings in these organs that are not the primary focus of the clinical question, are frequent in this region of the body. In particular, findings presumed to be unimportant, such as cystic masses in the liver, the bile duct system or the pancreas, initially appear to be irrelevant in the diagnosis. For the liver we define the mostly clearly diagnosable simple cysts and hemangiomas as leave me alone lesions. Otherwise, we recommend a classification of incidentalomas into the three major categories (<0.5â¯cm, 0.5-1.5â¯cm and >1.5â¯cm) as well as an assessment with respect to clearly benign and suspect imaging characteristics in the context of a classification of patients into three different risk groups.
