Rounded atelectasis, abbreviated RA, is a benign pathology of the lung that may be mistaken for lung cancer.[1][2]
General
- Benign clinical diagnosis.
- May be biopsied to exclude malignancy.
- Type of lung collapse[3] often associated with asbestos exposure.
Clinical (radiologic findings):[3]
- Pleural thickening.
- Mass lesion with "comet tail" (curvilinear opacification of bronchi and vessels).
Microscopic
Features:
- Pleural fibrosis.
- No features of malignancy.
Note:
- Findings on core biopsy are non-specific.
DDx:
- Pleural plaque.
Sign out
Lung Lesion, Right Lower Lobe, Core Biopsy: - Benign fibrous tissue and skeletal muscle. - NEGATIVE for lung parenchyma. - NEGATIVE for evidence of malignancy. Comment: Clinical correlation is suggested.
