Conventional roentgenograms and tomograms sometimes provide inconclusive evidence although CT can be highly accurate in both identifying and quantifying calcium content. An alternative method is dual-energy subtraction utilizing scanned projection digital radiography. Forty-one patients with solitary (occasionally multiple) pulmonary nodules were examined with the technique, employing second-generation fan-beam equipment: 28 nodules or masses were noncalcified and 13 calcified. Of the former, 20 were pathologically proved, 16 being malignant and 4 benign (2 granulomas, 2 bronchiectasis); in 3 of the remaining 8, a presumptive diagnosis was reasonably certain (1 granuloma, 2 metastases), while in 5 the diagnosis was not made. In 8 of the 13 calcified lesions, the diagnosis can reasonably be regarded as confirmed as granulomas; 5 are being followed up with that presumptive diagnosis.

Report of a Case A 57-year-old man gave an eight-month history of dysphagia, hoarseness, and postprandial coughing spells. His general health was good, and his only medication had been low-dose thioridazine hydrochloride for chronic schizophrenia, in remission. He had no other gastrointestinal problems. Physical examination was completely normal except for a mild reduction in rotational and flexion-extension movements of the neck. There were no noticeable musculoskeletal complaints. Results of a complete blood cell count, urinalysis, serologic test for syphilis, 12-factor automated blood chemistry analysis, and determinations of erythrocyte sedimentation rate, rheumatoid factor, and antinuclear antibody were all normal. A roentgenogram with a

No tumour was demonstrated elsewhere. Such a pattern of presentation has not previously been described in this condition. Malignant melanoma, even in the absence of disease elsewhere, should be considered in the differential diagnosis of such lesions seen on computed tomography.

It is conceivable that a patient may be studied by CT prior to plain radiography, and the appearance of the colon described below should alert the examiner to the possibility of toxic megacolon.

The CT findings in cavernous hemangioma and focal nodular hyperplasia were specific, and permitted accurate diagnosis of this lesion before biopsy. The CT appearance of all other lesions was variable. We consider CT useful in providing an accurate evaluation of the intrahepatic and extrahepatic extent of the neoplasm.
