A flaky low-density shadow with blurred borders is a description of a lesion within the spleen that belongs to a lung CT. A CT examination of the spleen reveals an uneven density and a flaky low-density shadow with no apparent border to the lesion itself. The most common lesions that present with the corresponding CT description include splenic infarction, splenic trauma, and intrasplenic tumors. 1. Splenic infarction: most of them are associated with abnormal coagulation function, and enhancement examination reveals localized wedge-shaped changes without obvious enhancement, with occlusion of the corresponding blood vessels. 2. Splenic trauma: with a history of trauma, uneven enhancement of the injury site will be found through enhanced examination, and some of them will be accompanied by a large amount of blood accumulation in the abdominal cavity. 3. Splenic tumor: enhancement of the lesion on enhanced scanning is inconsistent with the degree of enhancement of the surrounding spleen, and some of them are accompanied by an increase in tumor markers. The presence of intrasplenic flaky low-density shadow needs to be combined with enhanced examination and clinical history to make a comprehensive judgment. If there is obvious abdominal pain and decline in physical condition, it is necessary to consult a doctor in time for observation and standardized treatment under the guidance of clinicians.
