Purpose: To determine whether instillation of normal saline solution for sealing the needle track reduces incidence of pneumothorax and chest tube placement after computed tomography-guided percutaneous lung biopsy.

Materials And Methods: A total of 242 computed tomography-guided percutaneous lung biopsies performed at a single institution were retrospectively reviewed, including 93 biopsies in which the needle track was sealed by instillation of 3-5 ml of normal saline solution during needle withdrawal (water seal group) and 149 biopsies without sealing (control group). Patient and lesion characteristics, procedure-specific variables, pneumothorax and chest tube placement rates were recorded.

Background: Pulmonary mucormycosis (PM) is a life-threatening invasive mold infection. Diagnosis of mucormycosis is challenging and often delayed, resulting in higher mortality.

Research Question: Are the disease presentation of PM and contribution of diagnosis tools influenced by the patient's underlying condition?

Study Design And Methods: All PM cases from six French teaching hospitals between 2008 and 2019 were retrospectively reviewed.

In some cases of interstitial lung disease (ILD), clinical and biological findings associated with CT scan pattern during multidisciplinary discussion (MDD) fail to yield a confident diagnosis. In these cases, histology may be necessary. Transbronchial lung cryobiopsy (TBLC) is a bronchoscopic procedure that has been developed in recent years and currently contributes to diagnostic work-up in patients with ILD.

Background: Bronchoalveolar lavage (BAL) is a major diagnostic tool in interstitial lung disease (ILD). Its use remains largely quantitative, usually focused on cell differential ratio. However, cellular morphological features provide additional valuable information.

Background: Allergic bronchopulmonary aspergillosis (ABPA) is a bronchopulmonary disease caused by a complex hypersensitivity to Aspergillus and is usually associated with underlying respiratory diseases such as asthma or cystic fibrosis. Mucus plugging can lead to segmental or lobar atelectasis, but complete lung atelectasis has been exceptionally reported in the literature, making it difficult to diagnose. The diagnosis of ABPA may however be suggested in patients without known predisposing respiratory disorder, even in the absence of other relevant radiographic findings.
