A radiological and clinical correlative study of laryngeal abnormalities seen in Northern Alberta.
Contrast laryngograms performed on 50 patients referred to the radiology department of University Hospital between 1967 and 1973 were correlated with the direct laryngoscopic and pathological findings. Not a single malignancy in this series was missed radiologically, but in three out of 32 cases, the radiological extent of these lesions was considered more advanced than the pathology results. All patients with proven chronic inflammations, had symptoms of carcinomas of the larynx. No false positive carcinomas were diagnosed laryngographically in this group. In a patient with the nasopharyngeal carcinoma and in a case of myasthenia laryngis the radiological diagnosis would probably not have been misinterpreted if clinical histories were obtained prior to laryngography.
