Why Is Parallel Structure Important?, Requirement Gathering Tools For Business Analyst. and H.E. Lesions are heterogeneously hypoattenuating with hyperenhancement in areas of necrosis and areas of hemosiderin deposition with calcification on imaging [6, 40, 50, 52] . Another way to look at renal solid masses is to look at the shape. The liver may show reticular and lacelike calcifications with surrounding hyperattenuating, hemorrhagic as-cites [36, 37]. Chronic inflammation may lead to the formation of an inflammatory mass that may mimic a pseudotumor. Initially, ineffective hematopoiesis occurs as a result of bone marrow fibrosis and resultant endothelial-to-mesenchymal transition of greater than 30% of endothelial cells in the bone marrow microvasculature. Ancillary findings in some diseases can include calcified lymphadenopathy, septal thickening, and pleural calcification. Determining the cause of splenic lesions is essential to guide appropriate management; the pattern of calcification together with other imaging and clinical findings can aid with differentiation. Multifocal lesions in the liver may appear as hypoattenuating lesions with rim enhancement and associated capsular retraction [46]. Chemotherapy is required because of the high proportion of cases with metastatic disease, and splenectomy is also required due to the high risk of rupture [50]. Hydatid cysts can rupture either spontaneously or as a result of trauma, therefore the standard of treatment is spleen-conserving surgery when possible or total splenectomy [35]. 5D and 5E), also called the water lily sign [16, 32].
