Bottom Line: The second most common finding was consolidation (in 83.3% of cases), followed by peribronchovascular opacities (in 52.8%), reticulation (in 38.9%), bronchiectasis (in 33.3%), interstitial nodules (in 27.8%), interlobular septal thickening (in 27.8%), perilobular pattern (in 22.2%), the reversed halo sign (in 16.7%), airspace nodules (in 11.1%), and the halo sign (in 8.3%).The lesions were predominantly bilateral, the middle and lower lung fields being the areas most commonly affected.Ground-glass opacities and consolidation were the most common findings, with a predominantly random distribution, although they were more common in the middle and lower thirds of the lungs.

ABSTRACT

Objective: To determine the frequency of HRCT findings and their distribution in the lung parenchyma of patients with organizing pneumonia.

Methods: This was a retrospective review of the HRCT scans of 36 adult patients (26 females and 10 males) with biopsy-proven organizing pneumonia. The patients were between 19 and 82 years of age (mean age, 56.2 years). The HRCT images were evaluated by two independent observers, discordant interpretations being resolved by consensus.

Results: The most common HRCT finding was that of ground-glass opacities, which were seen in 88.9% of the cases. The second most common finding was consolidation (in 83.3% of cases), followed by peribronchovascular opacities (in 52.8%), reticulation (in 38.9%), bronchiectasis (in 33.3%), interstitial nodules (in 27.8%), interlobular septal thickening (in 27.8%), perilobular pattern (in 22.2%), the reversed halo sign (in 16.7%), airspace nodules (in 11.1%), and the halo sign (in 8.3%). The lesions were predominantly bilateral, the middle and lower lung fields being the areas most commonly affected.

Conclusions: Ground-glass opacities and consolidation were the most common findings, with a predominantly random distribution, although they were more common in the middle and lower thirds of the lungs.

f09: TCAR de tórax (janela de parênquima pulmonar) ao nível das bases pulmonares de um homem de 75 anos, mostrando opacidades reticulares basais bilaterais nas regiões posteriores dos pulmões.

Mentions: Os achados tomográficos mais comuns (Tabela 1), em ordem decrescente, foram os seguintes: opacidades em vidro fosco (Figura 1); consolidação (Figura 2); opacidades peribroncovasculares (Figura 3); reticulação (Figura 4); bronquiectasias; nódulos intersticiais; espessamento de septos interlobulares; padrão perilobular (Figura 5); sinal do halo invertido; nódulos do espaço aéreo e sinal do halo. Foram observados sinais de distorção arquitetural em 14 (38,9%) dos 36 pacientes.
