Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. Here we described a case of a 50-year-old woman with haemoptysis, cough and tachypnea, who was diagnosed with cholesterol pneumonia accompanying with pulmonary artery hypertension. The extremely high pulmonary artery pressure achieved, in this case, is alarming and should alert the physicians that the cholesterol pneumonia may be one of the underlying causes of pulmonary artery hypertension. After a treatment of methylprednisolone, her clinical symptoms were significantly improved, which suggested that steroid might be a promising therapeutic for patients with cholesterol pneumonia.

The application of radial probe endobronchial ultrasound (R-EBUS) and virtual bronchoscopic navigation has improved the diagnostic outcome of bronchoscopy for peripheral pulmonary lesions (PPLs). Nonetheless, while existing navigation systems are very useful for selecting the bronchus containing the target lesion, the associated introductory costs are high. Therefore, we focused on virtual bronchoscopy (VB) using the workstation, ziostation that was already available in many countries as an adjunct modality. ⋯ VB offered by the workstation was a valuable tool that facilitated more accurate and rapid bronchoscopy procedure for diagnosis of PPLs.

Case Reports
Partial pleural covering for intractable pneumothorax in patients with Birt-Hogg-Dubé Syndrome.
Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder associated with a germline mutation of the folliculin (FLCN) gene. Most patients with BHD have multiple pulmonary cysts, and are at high risk of repeated pneumothorax. Although an increasing number of patients are diagnosed with BHD by genetic testing, therapeutic approaches for intractable pneumothorax have not yet been described. ⋯ Partial pleural covering combined with resection of protruding cysts should be a safe and effective therapeutic approach for BHD patients with intractable pneumothorax. Further investigation is needed to establish a detailed protocol for treatment of pneumothorax that results in minimal functional impairment.

Comparative Study
The role of EBUS-TBNA and standard bronchoscopic modalities in the diagnosis of sarcoidosis.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an accurate and minimally invasive technique that has been shown to have excellent diagnostic yield in the diagnosis of mediastinal and hilar lymphadenopathy. However, endoscopic bronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) are still the standard method for making a pathologic diagnosis of sarcoidosis. The aim of this study was to compare the diagnostic yield of EBUS-TBNA and TBLB through a flexible bronchoscope in patients with stage I and II sarcoidosis. ⋯ The diagnostic yield of the EBUS-TBNA for stage I and II sarcoidosis is clearly higher than for TBLB and EBB. The combination of EBUS-TBNA with standard bronchoscopic techniques is safe and feasible, and optimizes the diagnostic yield in patients with pulmonary sarcoidosis and enlarged intrathoracic lymph nodes. EBUS-TBNA in combination with standard bronchoscopy may be considered to be the first-line investigation in patients with suspected sarcoidosis and enlarged intrathoracic lymphadenopathy.

Review Case Reports
Successful embolization in childhood hemoptysis due to abnormal systemic arterial bleeding of the lung and review of the literature.
Hemoptysis in children is a rare but potentially life-threatening symptom of an underlying respiratory tract abnormality. Hemoptysis, when massive and untreated, has a mortality rate of more than 50%. With interventional radiological procedures and surgery, this rate has dropped to 7%-18%. The experience with bronchial arterial embolization in childhood is very limited; only a few case reports with short-term follow-up have been reported. ⋯ Massive hemoptysis due to abnormal systemic bleeding of the lung in the absence of parenchymal disease is an uncommon and severe symptom in childhood. Embolization can be a treatment option in children with abnormal vasculature bleeding and can be repeated safely when needed.
