title: CT of splenic and perisplenic abnormalities in septic patients.
abstract: Splenic and perisplenic pathology, demonstrated by CT examination in 14 septic patients, was correlated with the clinical course and with surgical and pathologic findings available. Twelve patients were intravenous drug addicts and two patients developed bacteremia associated with bacterial endocarditis. The CT findings were divided into three groups: (1) Single wedge-shaped peripherally located defects were seen in five patients; there was good response to medical therapy without other complications. (2) Larger and/or multiple, rounded or oval lesions were present in five patients; two of these patients had splenic abscesses proven on subsequent splenectomy. (3) Multiple splenic lesions and fissures associated with perisplenic and subphrenic fluid collections were seen in four patients; infected splenic infarcts, splenic fractures, and infected perisplenic hemorrhagic fluid collections were found in this group of patients. The CT examination in septic patients can reliably demonstrate splenic and perisplenic pathology, and its appearance contributes greatly to the overall clinical assessment and surgical approach.
