We retrospectively reviewed CT scans of 18 patients (12 males and 6 females; mean age: 43.6 years) with the diagnosis of blunt splenic trauma. All patients underwent CT at different times after the trauma. The cases were divided into 2 groups: according to the time at which the CT was performed, the 1st group consisted of 11 patients scanned within 48 h after the trauma; the 2nd group consisted of 7 patients studied with CT at variable times after the traumatic event (mean time: 6.5 days; range 3-13 days). All lesions in the 1st group (11 patients) had indistinct margins, while lesions of patients in the 2nd group (7 patients) always showed clean-cut and regular edges. Early lesions were always hyperdense, late ones hypodense. CT diagnosis always matched the surgeon's diagnosis. We can confirm the diagnostic value of CT of splenic lesions in blunt abdominal traumas.

Ten patients with acute rupture of the thoracic aorta by blunt trauma were studied. In all instances chest radiographs, computed tomography and aortography were performed. A diagnostic algorithm is proposed for subjects with suspected acute rupture of the thoracic aorta.

Xerotomography was performed on 148 patients with proven or suspected tumors of the lung or mediastinum. Retrospectively they were compared to film tomography in 108 cases. In 64 patients, the results of histological examination were also available. Xerotomography proved diagnostically more effective than film tomography in 52 cases (48%), less effective in 6 cases (6%) and about equivalent in the remaining 50 cases (46%). Xerotomography appeared to be more effective in visualization of small peripheral nodes of moderate opacity. Xerotomography has to be a selected second-line technique for special cases, in particular for the study of coin lesions, for the search for cavitations and calcifications and for the study of pulmonary vessels.

Sixty-six patients with tumor of the distal esophagus and/or the gastric fundus were admitted for intrathoracic esophagogastroplasty. Surgical mortality was 6% (4 of 66 cases). There were 3 early and 7 late complications among the 62 remaining patients. The authors suggest that radiological examinations of patients after esophagogastroplasty should include an early examination on the 7th-10th day after surgery with water-soluble contrast medium for detection of early complications and double-contrast studies before dismissal, at later check-ups and whenever clinical symptoms of late complications are developing.
