Paracoccidioidomycosis imaging findings

Introduction

Overview

Overview

Common chest x-ray findings in chronic PCM include bilateral and symmetric opacities, butterfly wing pattern, architectural distorsion, paracicatricial emphysema and traction bronchiectasis. There are not many chest x-ray finding in acute PCM, but it is characterized by mediastinal and hiliar lymphadenopathy and pleural effusions.[1] On thoraxic CT scan, chronic paracoccidioidomycosis is characterized by ground-glass attenuation, airspace consolidations, interlobular septal thickening, nodular pattern, fibrotic pattern, cavitary lesions, halo sign and reversed halo sign.[1][2][3][4]
