“…Dense consolidations with intermingled air bronchograms were found in 6 patients (46.2%) in the present study. Therefore, PAM should be considered as a differential diagnosis for the dense consolidation pattern ( 23 , 29 , 34 , 35 ) , together with amiodarone pulmonary toxicity ( 37 ) , metastatic pulmonary calcification ( 38 - 41 ) , silicoproteinosis ( 42 , 43 ) , talcosis ( 44 - 46 ) and amyloidosis ( 47 - 49 ) .…”

ObjectiveThe present study was aimed at retrospectively reviewing high-resolution computed tomography (HRCT) findings in patients with pulmonary alveolar microlithiasis in order to evaluate the frequency of tomographic findings and their distribution in the lung parenchyma.Materials and MethodsThirteen patients (9 females and 4 males; age, 9 to 59 years; mean age, 34.5 years) were included in the present study. The HRCT images were independently evaluated by two observers whose decisions were made by consensus. The inclusion criterion was the presence of abnormalities typical of pulmonary alveolar microlithiasis at HRCT, which precludes lung biopsy. However, in 6 cases lung biopsy was performed.ResultsGround-glass opacities and small parenchymal nodules were the predominant tomographic findings, present in 100% of cases, followed by small subpleural nodules (92.3%), subpleural cysts (84.6%), subpleural linear calcifications (69.2%), crazy-paving pattern (69.2%), fissure nodularity (53.8%), calcification along interlobular septa (46.2%) and dense consolidation (46.2%).ConclusionAs regards distribution of the lesions, there was preferential involvement of the lower third of the lungs. No predominance of distribution in axial and anteroposterior directions was observed.

“…9 ); apices and costophrenic sulci are generally spared. In more advanced disease, thin-section CT shows progressive massive fibrosis associated with lower lobe emphysema and diffuse reticulonodular changes [ 101 ]. Although CT findings in advanced talcosis are similar to those reported in silicosis, conglomerate masses with areas of high attenuation usually involve the upper lung zones in silicosis, while in talcosis, they are distributed throughout all lung zones [ 11 100 ].…”

Non-infectious granulomatous lung disease represents a diverse group of disorders characterized by pulmonary opacities associated with granulomatous inflammation, a relatively nonspecific finding commonly encountered by pathologists. Some lesions may present a diagnostic challenge because of nonspecific imaging features; however, recognition of the various imaging manifestations of these disorders in conjunction with patients' clinical history, such as age, symptom onset and duration, immune status, and presence of asthma or cutaneous lesions, is imperative for narrowing the differential diagnosis and determining appropriate management of this rare group of disorders. In this pictorial review, we describe the pathologic findings of various non-infectious granulomatous lung diseases as well as the radiologic features and high-resolution computed tomography imaging features.

“…Conglomerated masses in silicosis usually involve the upper-lung zones, while in talcosis they are distributed throughout all lung zones [20,21]. In talcosis observed in soapstone artisans, interlobular septal thickening was found in all patients, in addition to small centrilobular nodules (75%) and ground-glass opacity (67%) [22]. Slight lymph node enlargement with increased attenuation is visible in some cases of talcosis (Fig.…”

Imaging diagnosis of classical and new pneumoconiosis: predominant reticular HRCT pattern

Our understanding of the manifestations of pneumoconioses is evolving in recent years. Associations between novel exposures and diffuse interstitial lung disease have been newly recognized. In advanced asbestosis, two types of fibrosis are seen, probably related to dose of exposure, existence of pleural fibrosis, and the host factor status of the individual. In pneumoconiosis of predominant reticular type, nodular opacities are often seen in the early phase. The nodular pattern is centrilobular, although some in metal lung show perilymphatic distribution, mimicking sarcoidosis. High-resolution computed tomography enables a more comprehensive correlation between the pathologic findings and clinically relevant imaging findings. The clinician must understand the spectrum of characteristic imaging features related to both known dust exposures and to historically recent new dust exposures.
