The spectrum of X-ray findings in 20 cases of Wegener's granulomatosis have been described. The pulmonary findings are most frequent and range from the rather typical cavitating nodule to the uncommon presentation of lobar consolidation and hilar mass.
Pneumothorax is an unusual manifestation of Wegener granulomatosis. Two cases are presented which illustrate a definite association between the entities. Pneumothorax may be the initial and only pulmonary manifestation, or it may occur in combination with other evidence of the disease.
Four cases of esophageal candidiasis complicating functional or mechanical obstruction are described. The causes of the obstruction included achalasia, scleroderma, and postoperative fundoplication. None of the commonly recognized conditions predisposing to esophageal candidiasis was present. The findings on barium study ranged from plaque-like filling defects to extensive nodularity and roughening of the mucosal surface, which must be distinguished from ingested debris. It is suggested that esophageal stasis of any cause can lead to candidiasis.
The role of the double-contrast enema examination (DCE) in the detection of rectal carcinoma was evaluated and compared to the proctoscopic examination. Records of 90 consecutive patients with a diagnosis of rectal carcinoma were reviewed. Sixty-six patients had a preoperative DCE. The correct diagnosis was either made or suggested in 91% of these patients. The proctoscopic examination was diagnostic in 86%. The causes of radiologic and proctoscopic error were evaluated. Findings confirm that the DCE is an accurate method for the diagnosis of rectal carcinoma. Careful examination of the rectum should be incorporated in all radiologic studies of the colon since a normal proctoscopic examination does not exclude the possibility of rectal carcinoma.
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.
