Abstract
The diagnosis of aspergillosis in the paranasal sinuses is preoperatively difficult to make in spite of the increasing number of reports showing its prevalence. However, because symptoms are usually non-diagnostic and infection is usually confined to a single sinus, X-ray findings are often suspect for possible neoplasm. We have studied six patients with aspergillosis, all of whom were suspected of having sinus tumors, but were otherwise healthy persons. Affected sinuses were examined by CT and the diagnosis of non-invasive aspergillosis was confirmed by operation. In this report, we have compared the CT and X-ray findings in our cases of aspergillosis. These findings indicate that CT is useful in the preoperative diagnosis of sinus aspergillosis.
