86 cases of solitary air cysts of the lung (6.83% of all maldevelopments) were analyzed. This maldevelopment of bronchial tree is found most often in men (10:7) and more often in the right lung than in the left (18:13). There were no clinical symptoms in 33 (38.37%) patients. Uncomplicated course of the disease was in 51 (59.3%) patients, the disease was complicated by infection in 28 (32.56%) patients. Solitary bronchial cysts were complicated by spontaneous pneumothorax in 8.14% cases, by hemoptysis--in 6.98%. Roentgenography of the chest thorax on two projections and tomography (including CT) are enough for diagnosis of solitary air bronchial cysts. Bronchoscopy, bronchography and APG are not much informative in diagnosis of cysts and should be used on special indications. Cystectomy or cystectomy with partial resection of lung tissue were performed in 67.14% patients with good results.

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens.

Background And Objective: Pulmonary nodules (PNs) are small (≤3 cm) radiographic opacities within lung parenchyma. The use of low-dose computed tomography (LDCT) has led to a significant increase in the identification of solitary nodules. Malignant lung nodules comprise only 5% of all nodules, with management differing greatly from benign cases.

Background: This study explores the value of interlobar fissure semilunar sign(IFSS) based on multifactor joint analysis in predicting the invasiveness of ground glass nodules(GGNs) with interlobar fissure attachment in the lungs.
Methods: This was a retrospective analysis of clinical data and CT images of 203 GGNs attached to the interlobar fissures confirmed by surgery and pathology. According to pathological results, those GGNs were divided into three groups: glandular precursor lesion (atypical adenomatous hyperplasia/adenocarcinoma in situ), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (IAC).

Domestic ferrets (Mustela putorius furo) are an emerging model species in biomedical research. While behavioral studies are a critical translational tool for evaluating neurologic function in disease models and toxicology studies, there is a lack of ferret-specific behavioral assays and corresponding data on baseline behavior. Play behavior is a promising target for evaluation of psychological well-being, particularly because ferrets engage in solitary and social play well into adulthood.
