• <B><I>Background</I>.</B> Recently, screening CT has been increasingly used for the detection of lung cancer. We occasionally encounter atypical adenomatous hyperplasia (AAH) which demonstrated CT features similar to small bronchioloalveolar carcinoma (BAC) of the lung. <B><I>Purpose</I>.</B> To analyze the radiographic characteristics of the lesions of AAH of the lung that can be detected by thin-section CT (TS-CT). <B><I>Material and Methods</I>.</B> A retrospective study was carried out on patients with AAH who were surgically resected at Kanagawa Cancer Center. Through TS-CT, 26 AAH lesions were identified in 23 patients. The lesions were classified into two types according to attenuation of on TS-CT images as the "air-containing type" or the "solid-density type". Several parameters were evaluated on TS-CT to characterize these lesions, including their location, size, shape, border and internal density, convergence of the surrounding pulmonary vessels toward the nodules, and presence of pleural indentation detected on TS-CT. <B><I>Results</I>.</B> All 26 AAHs were found to be the air-containing type. The air-containing type lesions were further divided into two different growth patterns: a complete air-containing type (n=23) and an incomplete air-containing type (n=3). Characteristics observed on TS-CT images consisted of a homogeneous ground-glass attenuation in 77%, pleural indentations in 35%, vascular involvement in 85%, and air bronchogram in 38%. <B><I>Conclusion</I>.</B> Some cases with lesions of AAH showed the same findings a localized BAC on TS-CT. To obtain more precise differential diagnosis of AAH of the lung, it is necessary to accumulate more information concerning radiologic-pathologic correlation.
