INTRODUCTION: The presence of endometrial tissue in airways, pleura and lung parenchyma is called thoracic endometriosis syndrome (TES). It is a rare pathology, and typically consists of catamenial pneumothorax, haemothorax, haemoptysis, and pulmonary nodules. We report a case of a 36-year-old woman with thoracic endometriosis causing catamenial haemothorax. CONCLUSIONS: The diagnosis of thoracic endometriosis is complicated and often delayed. TES should be suspected in a reproductive age woman with exacerbating symptoms during the menstruation...

BACKGROUND: Localizing small or deep pulmonary nodules or subsolid ground-glass opacities often is difficult during video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracoscopic surgery (RATS). This can result in larger resections or conversion to thoracotomy. The goal of this study is to evaluate the role of electromagnetic navigational bronchoscopic localization (ENBL) as a safe and accurate intraoperative method to localize small, deep, or subsolid nodules. METHODS: This is a single-institution, single-surgeon retrospective study of all patients (51) who underwent combined ENBL and resection of 54 nodules between May 2013 and August 2015...

BACKGROUND: Computed tomography-guided needle biopsy (CTNB) is a well-established and commonly used technique for diagnosing pulmonary nodules with high accuracy and safety. Needle-tract implantation after CTNB has been reported in various reports. The aim of this study is to evaluate whether preoperative CTNB affected the distant metastasis and overall survival in pathological stage I-II lung cancer patients. METHODS: A total of 1,234 patients with pathological stage I-II non-small cell lung cancer were collected...

BACKGROUND: Current understanding of human immunodeficiency virus (HIV)-associated pulmonary cryptococcosis (PC) is largely based on studies performed about 2 decades ago which reported that the most common findings on chest radiograph were diffuse interstitial infiltrates. Few studies are available regarding the computed tomography (CT) findings. The aim of this study was to characterize chest CT features of HIV-associated PC. METHODS: HIV patients with cryptococccal infection and pulmonary abnormalities on Chest CT between September 2010 and May 2016 in the Second Affiliated Hospital of the Southeast University were retrospectively analyzed...

AIM: The most ubiquitous chest diagnostic method is the chest radiograph. A common radiographic finding, quite often incidental, is the nodular pulmonary lesion. The detection of small lesions out of complex parenchymal structure is a daily clinical challenge. In this study, we investigate the efficacy of the computer-aided detection (CAD) software package SoftView™ 2.4A for bone suppression and OnGuard™ 5.2 (Riverain Technologies, Miamisburg, OH, USA) for automated detection of pulmonary nodules in chest radiographs...

Benign metastasizing leiomyoma (BML) is a rare condition in which a benign uterine leiomyoma causes metastasis, mainly to the lungs. The patient was a 72-year-old woman who had undergone hysterectomy for an uterine leiomyoma at 37 years of age. Between the ages of 52 and 68 years, she had undergone 5 metastatectomies for 10 BMLs. At the current presentation, 2 nodules located in the right upper lobe of the lung were resected. The histological diagnosis was BML, and immunohistochemical staining demonstrated that the tumor cells were positive for estrogen and progesterone receptors...

The optimal treatment of pituitary carcinomas (PC) is unknown. Treatment includes surgical resection, radiation, and more recently, temozolomide (TMZ). Pituitary adenomas have relatively high expression of vascular endothelial growth factor; therefore, bevacizumab, an antiangiogenic agent, has been used in a small number of aggressive or malignant pituitary tumors after recurrence. However, it has not been administered concurrently with other chemotherapeutic agents or combined with radiation therapy in PC...

PURPOSE: In our previous study, we developed a computer-aided diagnosis (CADx) system using imaging findings annotated by radiologists. The system, however, requires radiologists to input many imaging findings. In order to reduce such an interaction of radiologists, we further developed a CADx system using derived imaging findings based on calculated image features, in which the system only requires few user operations. The purpose of this study is to check whether calculated image features (CFT) or derived imaging findings (DFD) can represent information in imaging findings annotated by radiologists (AFD)...

Conventional projection radiography (chest x‑ray) is one of the most frequently requested procedures in radiology. Even though chest x‑ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. This is due to the relatively low sensitivity of chest x‑rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be clinically symptomatic. Recommendations from relevant societies for the management of incidental findings, apart from the clarification of incidental nodules, do not exist...

BACKGROUND: Scrub typhus, a febrile illness of substantial incidence and mortality, is caused by infection with the obligately intracellular bacterium Orientia tsutsugamushi. It is estimated that there are more than one million cases annually transmitted by the parasitic larval stage of trombiculid mites in the Asia-Pacific region. The antigenic and genetic diversity of the multiple strains of O. tsutsugamushi hinders the advancement of laboratory diagnosis, development of long-lasting vaccine-induced protection, and interpretation of clinical infection...

RATIONALE: Guidelines for pulmonary nodule evaluation suggest a variety of strategies, reflecting the lack of high-quality evidence demonstrating the superiority of any one approach. It is unclear whether clinicians agree that multiple management options are appropriate at different levels of risk and whether this impacts their decision-making approaches with patients. OBJECTIVES: To assess clinicians' perceptions of the appropriateness of various diagnostic strategies, approach to decision-making, and perceived clinical equipoise in pulmonary nodule evaluation...

Subglottic stenosis is an uncommon structural abnormality that can pose as a difficulty for patients undergoing surgery, and treatment is complex due to the special anatomical location. Pulmonary nodule resection in patients with subglottic stenosis is challenging and has not yet been reported. Here we present a case of pulmonary nodule resection in a patient with subglottic stenosis using uniportal thoracoscopy under spontaneous ventilation anesthesia (SVA). Compared with traditional double lumen endotracheal intubation, we believe this modified technique can significantly reduce airway trauma, and accelerate patient recovery...

Pulmonary infections and lung cancer can resemble each other on radiographic images, which makes it difficult to diagnosis accurately and apply an appropriate therapy. Here we report two cases that two postoperative patients with lung adenocarcinoma developed diffuse nodules in bilateral lungs in a month which needed to be distinguished between metastatic malignancies and infectious diseases. Although there are much similarities in disease characteristics of two cases, patient in case one was diagnosed as acute miliary pulmonary tuberculosis (TB) while patient in case two was diagnosed as metastatic disease...

Histoplasmosis is a genus of dimorphic fungi having various varieties of which the commonest one causing infection is Histoplasma capsulatum known to cause histoplasmosis. It has a varied disease spectrum ranging from an acute infection to chronic disease especially in lungs, disseminated disease and cutaneous disorder. Histoplasma capsulatum usually causes subclinical infection and serious infections only manifest in immunocompromised patients. Frank cases of infection are seen in pulmonary histoplasmosis...

OBJECTIVE: To assess whether quantitative computed tomography (CT) can help predict histological invasiveness of pulmonary adenocarcinoma appearing as pure ground glass nodules (pGGNs). METHODS: A total of 110 pulmonary pGGNs were retrospectively evaluated, and pathologically classified as pre-invasive lesions, minimally invasive adenocarcinoma (MIA) and invasive pulmonary adenocarcinoma (IPA). Maximum nodule diameters, largest cross-sectional areas, volumes, mean CT values, weights, and CT attenuation values at the 0th,2th,5th, 25th, 50th,75th, 95th, 98th and100th percentiles on histogram, as well as 2th to 98th, 5th to 95th, 25th to 75th,and 0th to 100thslopes, respectively, were compared among the three groups...
