AbstractThe purpose of this study was to evaluate the high-resolution computed tomography (HRCT) findings of patients with the reversed halo sign (RHS) and to identify distinguishing features among the various etiologies. Two chest radiologists reviewed the high-resolution CT scans of 79 patients with RHS and determined CT findings by consensus. We studied the morphological characteristics, number of lesions, and presence of features associated with RHS. Forty patients presented with infectious diseases (paracoccidioidomycosis, tuberculosis, zygomycosis, invasive pulmonary aspergillosis, Pneumocystis jiroveci pneumonia, histoplasmosis, cryptococcosis) and 39 presented with noninfectious diseases [cryptogenic organizing pneumonia, pulmonary embolism, sarcoidosis, edema, lepidic predominant adenocarcinoma (formerly bronchioloalveolar carcinoma), Wegener granulomatosis]. RHS walls were smooth in 58 cases (73.4%) and nodular in 21 cases (26.6%). Lesions were multiple in 44 cases (55.7%) and single in 35 cases (44.3%). The presence of nodular walls or nodules inside the halo of RHS is highly suggestive of granulomatous diseases. |
