Location. Calcified lesions are very frequent among coronary artery disease stenotic lesions. Four cases of calcification were noted on CT in 38 consecutive bladder scans (10.5%). In cases in which splenic lesions on CT may not have a characteristic pattern of attenuation or enhancement, the morphologic features and pattern of calcifications can help the differential diagnosis [2]. CT imaging shows a calcified nodule in the subcutaneous layer . J Gastrointest Surg. 30(5): p. 36886. These posttraumatic cysts may show differential attenuation because of layering blood products and thick, curvilinear or plaquelike calcifications within a thick fibrous wall [1214].
