“…The combination of cysts and nodules, which spare the lung bases, in a male smoker, is sufficient for a confident diagnosis of LHC. (120) In women smokers, lymphangioleiomyomatosis (LAM) should be considered, since nodules (and cysts) can also be present. (121) Langerhans cells can be identified in BAL fluid, although the sensitivity and specificity of this test are quite low.…”

High-resolution computed tomography (HRCT) is the radiological imaging technique best suited to revealing changes in lung structure. Various HRCT findings, taken together, can represent typical patterns. These patterns, in conjunction with the anatomical distribution of findings and with clinical data, can narrow the differential diagnosis of diffuse interstitial lung disease and, in many cases, indicate the correct diagnosis with a high degree of accuracy. The most common HRCT patterns seen in cases of diffuse interstitial lung diseases are the nodular pattern, linear/reticular opacities, cystic lesions, ground-glass opacities and consolidations. This article reviews the correlations between HRCT patterns and pathologic findings, summarizing the most common causes, as well as detailing the methods of investigation employed in order to diagnose the most common types of chronic diffuse lung disease.Keywords: Lung diseases, interstitial/pathology; Tomography, X-Ray computed; Diagnostic techniques, respiratory system. ResumoA tomografia de alta resolução (TCAR) é a técnica de imagem radiológica que reflete mais de perto as alterações da estrutura pulmonar. Os vários achados tomográficos podem ser combinados para formar padrões típicos. Estes, conjuntamente com a distribuição anatômica dos achados, e com os dados clínicos, podem estreitar o diagnóstico das doenças intersticiais pulmonares difusas, e em vários casos sugerir o diagnóstico correto com alto grau de acurácia. Os padrões mais comuns das doenças intersticiais pulmonares difusas na TCAR são o nodular, linear e reticular, lesões císticas, opacidades em vidro fosco e consolidações. Este artigo revisa as correlações entre os padrões tomográficos na TCAR e os achados patológicos e resume as causas mais comuns e os métodos de investigação para se atingir um diagnóstico nas doenças pulmonares crônicas difusas mais comuns.Descritores: Doenças pulmonares intersticiais/patologia; Tomografia computadorizada por raios X; Técnicas de diagnóstico do sistema respiratório.* Study carried out in the

“…HRCT imaging has the greatest diagnostic value and is necessary to perform for confirmation of diagnosis. In a previous study, the diagnostic accuracy of LAM was found to be 72% by CT alone (14). The diagnosis of LAM requires a HRCT scan that demonstrates diffuse, round or ovoid, thin-walled cysts, which vary in size between a few millimeters and 3 cm, and are surrounded by normal pulmonary parenchyma, while in advanced stages of the disease, total replacement of the lung tissue may be observed (5).…”

Abstract. Lymphangioleiomyomatosis (LAM) is an extremely rare lung disease affecting females of a childbearing age. The condition occurs sporadically or in association with tuberous sclerosis complex. The diagnosis of LAM is often delayed since the clinical symptoms and signs are non-specific. The present study reports the a case of a patient with LAM, in which bloody sputum was presented as the initial symptom. The 43-year-old female had experienced a small amount of bloody sputum over the previous five years. The patient was admitted to the Department of Respiratory Medicine at Taizhou People's Hospital (Taizhou, China) in 2012, reporting symptoms of a cough, shortness of breath and bloody sputum over the previous 10 days. A high-resolution computed tomography scan revealed multiple small circular thin-walled translucent areas in both lung fields. The initial diagnosis of the patient was LAM. A biopsy was performed using a video-assisted thoracoscopy. In conclusion, increased awareness and early diagnosis and treatment were determined to be key factors in ensuring a satisfactory prognosis.

Birt-Hogg-Dubé syndrome is characterized by clinical manifestations such as hamartomas of the skin, renal tumors and lung cysts with spontaneous pneumothoraces. Patients with Birt-Hogg-Dubé syndrome may present with only multiple lung cysts. We report the chest computerized tomography (CT) features of three patients with BirtHogg-Dubé syndrome. Each patient had multiple lung cysts of various sizes according to chest CT evaluation, most of which were located in lower lobes and related to pleura. The identification of unique characteristics in the chest CT of patients with Birt-Hogg-Dubé syndrome may provide an efficient mechanism for diagnosis. Key Words: Birt-Hogg-Dubé syndrome, chest CT, lung cyst ÖzetBirt-Hogg-Dubé sendromu, klinik olarak deri hamartomları, renal tü-mörler ve spontan pnömotoraksla birlikte olan akciğer kistleri ile karakterizedir. Birt-Hogg-Dubé sendromu tanısı alan hastalarda sadece multipl akciğer kistleri olabilir. Biz burada Birt-Hogg-Dubé sendromlu üç hastada toraks bilgisayarlı tomografi (BT) bulgularını sunduk. Toraks BT incelemesinde tüm hastalarda farklı boyutlarda çok sayıda akciğer kisti vardı. Kistlerin çoğu alt loblarda ve plevra ile ilişkiliydi. Toraks BT bulguları, bu sendromun rastlantısal tanısı için önemli bir yol gösterici olabilir.

Chronic Cystic Lung Disease: Diagnostic Accuracy of High-Resolution CT in 92 Patients

Abstract: Although various chronic cystic lung diseases often have a characteristic appearance that allows their distinction on high-resolution CT, considerable overlap exists among the CT findings. Therefore, lung biopsy is often required for a definitive diagnosis.
