The computed tomographic (CT) findings in 52 patients with histologically proved esophageal carcinoma were reviewed. In 30 of these patients, the CT findings were correlated with findings at surgery or autopsy. CT was found to be highly accurate in predicting tumor size and assessing invasion of the tracheobronchial tree and spread to the liver, adrenals, and celiac and left gastric nodes. By quantifying the contact between the tumor and aorta, it was found that the CT appearance correctly predicted the presence or absence of aortic invasion in 24 of 25 cases (five cases were indeterminate). CT was insensitive in detecting metastatic spread to local periesophageal nodes; in these cases the tumor tended to involve the nodes without enlarging them. CT is an accurate method for assessing the spread of esophageal carcinoma. Its use can prevent unnecessary surgery in patients with inoperable tumors.
Nodular hepatosplenic sarcoidosis is associated with organomegaly, adenopathy, and symptoms. Nodules were not associated with advanced lung disease and did not herald a change in chest radiographic stage. An elevated ACE level may be helpful in diagnosis.
Barium examination of the esophagus is often useful for evaluating the cause of dysphagia, a frequent condition in patients who have undergone total laryngectomy. The examination may be difficult to interpret, however, because a variety of anatomic changes may be produced by radiation, infection, fistula, recurrent tumor, or the operation itself. Radiographic and clinical information on 45 total-laryngectomy patients, whose follow-up periods ranged from six months to 17 years, were analyzed. A recurrent tumor was found in 15 patients and was evident radiographically as a mass deviating the neopharynx in 14. Benign strictures in 14 patients appeared either as a long symmetrical narrowing or as a very short, weblike narrowing. Fistulas were demonstrated in 13 patients and presaged the development of recurrent tumors in five. Cricopharyngeal muscular dysfunction accounted for dysphagia in five cases. An understanding of these patterns leads to more accurate interpretation of the postoperative barium examination of the esophagus, and the radiographic findings often indicate the correct diagnosis with a high degree of confidence.
OBJECTIVE.The purpose ofour study was to determine the prevalence, distribution, and clinical Clinical indications for and therapy during ERCP were correlated with radiographic findings.
RESULTS.Of the 94 patients with pancreas divisum, 54 (57%) had radiographic evidence of pancreatitis.Of these 54 patients, 44 had at least one episode of clinically documented pancreati-
CONCLUSION.In our population ofpatients referred for ERCP and found to have pancreas divisum, the prevalence ofpancreatitis was very high and usually was limited to a dorsal distribution.Received October 29, 1998; accepted after revision January8, 1999.Presented at the annual meeting of the American
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
