CT of splenic and perisplenic abnormalities in septic patients.

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.

Computed tomographic recognition of gastric varices.

The computed tomographic (CT) findings in 13 consecutive patients with proven gastric varices were analyzed and correlated with the radiographic, angiographic, and gastroscopic evaluations. In 11 patients, CT clearly identified large (five) or smaller (six) varices located mainly along the posteromedial wall of the gastric fundus and proximal body of the stomach. Well defined rounded or tubular densities that enhanced during intravenous administration of contrast material and could not be distinguished from the gastric wall were identified. Dense, enhancing, round or tubular, intraluminal filling defects were seen in the cases where the stomach was distended with water. In two patients, the CT diagnosis of gastric varices could not be confidently made. All patients had associated intraabdominal collateral circulation, situated medial to the stomach within the lesser omentum, along the distribution of the coronary venous system. In seven patients, the CT examination correctly diagnosed the pathogenesis of gastric varices by identifying hepatic cirrhosis, calcific pancreatitis, and carcinoma of the pancreas.

The impact of CT in clinical management of pelvic and acetabular fractures.

Thirty-eight consecutive patients admitted to the hospital with pelvic and acetabular fractures underwent CT examination. The axial plane of CT is shown to be the most suitable for evaluation of these fractures. The fracture pattern is readily demonstrated, facilitating fracture classification. The degree of fracture fragment displacement and rotation, hip joint stability, and intra-articular osseous fragments can be determined. A number of unsuspected fractures were detected, including five sacral and four anterior acetabular wall fractures; the latter were due to extension of superior ramus fractures. Soft tissue injuries included several hematomas, serosanguinous cysts in one patient, and bladder laceration in one patient. It is concluded that in patients with pelvic fracture CT examination is the method of choice following preliminary radiographic evaluation, if further radiographic investigation is deemed necessary.
