“…The most frequent symptoms of mucinous adenocarcinoma are sputum production, coughing, shortness of breath and fever. The findings of computed tomography (CT) usually include ground-glass opacity (GGO) and consolidation (3,4). These clinical and radiographic features sometimes resemble those of bacterial pneumonia; therefore, a careful clinical and radiologic evaluation must be followed by the selection of an optimal procedure for obtaining diagnostic tissue.…”

Invasive Mucinous Adenocarcinoma Mimicking Organizing Pneumonia Associated with <i>Mycobacterium fortuitum</i> Infection

We herein report the case of a 68-year-old man diagnosed with invasive mucinous adenocarcinoma of the lungs. Chest computed tomography showed subpleural ground-glass opacity and small nodules with cavitation. A culture of the bronchoalveolar lavage fluid resulted in the detection of Mycobacterium fortuitum. The patient's lung consolidation rapidly progressed; however, repeated bronchoscopy showed no atypical cells, thus suggesting a diagnosis of organizing pneumonia associated with M. fortuitum infection. However, the surgical biopsy specimen was diagnostic for adenocarcinoma, with no mycobacterial infection. Invasive mucinous adenocarcinoma should not be excluded in the differential diagnosis of patients with clinical features of organizing pneumonia and nontuberculous mycobacterium infection, even if a transbronchial biopsy confirms the absence of malignancy.

“…While lymphatic and small airway obstruction was not evident at autopsy in this case, obstruction by mucin filled alveoli may have contributed to a similar effect. An alternate explanation could be “pseudocavitation,” whereby the central bubble‐like low attenuating regions within pulmonary nodules represented patent small airways or distended alveolar spaces under traction from malignant cells growing along alveolar walls 4.…”

This 52‐year‐old male ex‐smoker presented with a six‐month history of progressive breathlessness and weight loss. He deteriorated acutely, and was admitted with severe type 1 respiratory failure. Apart from diffuse coarse crackles on chest auscultation, physical examination was unremarkable. High‐resolution computed tomography (HRCT) showed diffuse cystic changes throughout the lungs. A diagnosis of pulmonary Langerhans cell histiocytosis (PLCH) was considered. Further workup identified a coincidental pancreatic lesion of uncertain significance, which remained indeterminate on magnetic resonance imaging (MRI) and on positron emission tomography (PET). Transbronchial biopsy revealed enteric differentiated adenocarcinoma exhibiting lepidic spread, and autopsy later confirmed primary pancreatic malignancy. This case demonstrates that metastatic pancreatic malignancy can present with severe respiratory failure and masquerade as cystic lung disease.

“…(12) Most of these nodules are semisolid, with solid and ground-glass components, as well as exhibiting irregular borders and pleural indentation. (7) Although cavitation is rare in the initial presentation, some nodules can have focal lucent areas, known as pseudocavitation ( Figure 1). (7,13) There might be cavitation after chemotherapy (Figure 2).…”

Bronchioloalveolar carcinoma has various presentations and a wide spectrum of imaging patterns, as does adenocarcinoma with a bronchioloalveolar component. The objective of this essay was to describe and illustrate the CT findings that are most characteristic of these tumors. Three presentations are described: solitary pulmonary nodule, consolidation, and diffuse pattern. The last two should be included in the differential diagnosis, together with infectious diseases. Knowledge of the various presentations and the use of proper diagnostic procedures are crucial to early diagnosis and to improving survival.Keywords: Lung neoplasms; Adenocarcinoma, bronchiolo-alveolar; Tomography, X-ray computed. ResumoO carcinoma bronquíolo-alveolar e os adenocarcinomas mistos com componente bronquíolo-alveolar têm apresentações variadas e múltiplos padrões por imagem. O objetivo deste ensaio foi descrever e ilustrar os achados mais característicos desses tumores em TC. São descritas três apresentações: nódulo pulmonar solitário, consolidação e apresentação difusa, sendo que as duas últimas são importantes no diagnóstico diferencial com acometimento infeccioso. O conhecimento das diversas apresentações e a utilização de propedêutica diagnóstica adequada são definitivos para o diagnóstico precoce e o aumento na sobrevida.Descritores: Neoplasias pulmonares; Adenocarcinoma bronquíolo-alveolar; Tomografia computadorizada por raios X. * Study carried out at Multimagem Diagnósticos, Goiânia, at Fleury Medicine and Health, São Paulo, and at the Heart Hospital, São Paulo, Brazil.

(11) Although there is a need for universally accepted criteria for subtypes of adenocarcinoma, the authors of the proposal are aware that there will be a period of adaptation to the new terms and recommend that they be initially used concomitantly with the current nomenclature.

Imaging patterns of BAC and adenocarcinoma with a bronchioloalveolar component Pulmonary nodule and focal groundglass opacitiesA solitary pulmonary nodule, usually in the periphery of the upper lobes, is described as the most common CT finding in BAC and adenocarcinoma with a bronchioloalveolar component.
