Unexpected subdiaphragmatic findings on CT of the chest in septic patients after cardiac surgery.

AIM: to draw the attention to upper abdominal abnormalities, which may be revealed incidentally in patients referred for a chest computed tomography (CT) after cardiac surgery. MATERIALS AND METHODS: We reviewed prospectively and retrospectively the CT results of all patients referred for a chest CT, with suspected sternal infection or for other reasons, after cardiac surgery, to assess possible upper abdominal disease as visualized on lower cuts of the chest CT with abdominal windows. RESULTS: Out of a total of 205 patients in the study 39 (19%) had unexpected abdominal abnormalities. The organs involved in decreasing order of frequency were the spleen (n = 18), gallbladder (n = 15), pancreas (n = 9), kidneys (n = 6) and bowel (n = 3). Many patients had involvement of more than one organ. The lesions were mainly ischaemic and/or infectious in origin. These findings led to interventional procedures in 13 (33%) of the patients with a good outcome. CONCLUSIONS: We found a relatively high prevalence of abdominal abnormalities on CT of the chest in patients referred with suspected thoracic problems after cardiac surgery. Major findings on CT led to changes in the management of these patients. We recommend therefore viewing lung bases with abdominal windows as well as adding sections through the upper abdomen in patients who are referred for a chest CT after cardiac surgery with suspected thoracic problems.

Calcification in lymphoma occurring before therapy: CT features and clinical correlation.

OBJECTIVE: Calcification in lymphoma occurring before therapy is rare. We assessed the prevalence, CT features, and clinical significance of calcification in nodes and masses in patients with lymphoma occurring before therapy. SUBJECTS AND METHODS: CT of the chest, abdomen, and pelvis of 956 newly diagnosed patients with lymphoma was evaluated prospectively for calcifications in enlarged lymph nodes and lymphoma masses. Findings were correlated with histologic type of disease, tissue parameters, and clinical course. Calcifications were further evaluated on follow-up CT. RESULTS: Of 956 patients with lymphoma (704 with non-Hodgkin's lymphoma and 252 with Hodgkin's lymphoma), eight patients (0.84%) showed calcifications in involved sites, seven of whom had non-Hodgkin's lymphoma and one of whom had Hodgkin's lymphoma. Calcifications were present in lymph nodes and masses in the mediastinum in five patients, in the retroperitoneum in two patients, and in the adrenal in one patient. All eight patients had the aggressive type of lymphoma. Four patients later relapsed, one of whom died. A fifth patient died after only minimal response to treatment. CONCLUSION: Calcification in patients with lymphoma occurring before therapy is rare as opposed to that in lymphoma after therapy. It occurred in our patients more often in the mediastinum, in patients with non-Hodgkin's lymphoma rather than in patients with Hodgkin's lymphoma, and only in patients with the aggressive type of disease.
