Sclerosing Variant of the Bronchioloalveolar Carcinoma : Imaging Findings in an Atypical Case

Abstract EN

Bronchioloalveolar carcinoma remains one of the most enigmatic lung cancers, demonstrating varied growth patterns, mixed histological features, and confusing clinical manifestations.

This paper reports a case of an unusual form of presentation: a sclerosing type associated with desmoplastic reaction and cicatrization.

A 75-year-old woman was admitted with persistent dry cough and progressive dyspnea.

Physical examination showed bilateral inspiratory crackles.

A chest radiograph and high-resolution computed tomography demonstrated confluent airspace nodules, forming areas of consolidation in both lungs, with signs of architectural distortion.

The lung biopsy revealed a nonmucinous sclerosing bronchioloalveolar carcinoma.
