Widespread fluffy airspace opacities, with almost complete white-out of the mid and lower zones on the left. Extensive airspace opacities with numerous air bronchograms. Trace of pleural fluid on the left only. No significant nodal enlargement. Chest x-ray demonstrates extensive and widespread fluffy airspace opacities, with almost complete white-out of the mid and lower zones on the left.

CT confirms extensive airspace opacities with numerous air-bronchograms. No pleural effusions or evidence of mediastinal adenopathy. Sputum, right and left main bronchus lavage were positive for malignant cells consistent with carcinoma. A Tru-cut biopsy was suggested by the pathologist to confirm the diagnosis of bronchoalveolar carcinoma , the patient's condition meant that this was not possible.

Carcinoma bronquíolo-alveolar

Bronchioloalveolar carcinoma: aspects in high-resolution computed tomography. Abstract Bronchioloalveolar carcinoma is a bronchogenic carcinoma that presents an insidious growth, arises from the walls of the distal air spaces and spreads using the alveolar septa as a stroma, preserving the lung architecture. In this work we analyze the high-resolution computed tomography of 17 patients with bronchioloalveolar carcinoma. Cavitated nodules, atelectasis, halo sign and "tree in bud" pattern were observed in only one case each. Key words: Bronchioloalveolar.

In situ pulmonary adenocarcinoma AIS —previously included in the category of " bronchioloalveolar carcinoma " BAC —is a subtype of lung adenocarcinoma. It tends to arise in the distal bronchioles or alveoli and is defined by a non-invasive growth pattern. This small solitary tumor exhibits pure alveolar distribution lepidic growth and lacks any invasion of the surrounding normal lung. Although the entity of AIS was formally defined in see History , it represents a noninvasive form of pulmonary adenocarcinoma which has been recognized for some time. AIS is not considered to be an invasive tumor by pathologists , but as one form of carcinoma in situ CIS.
