Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

The aim of the present study was to examine the value of window technique in qualitative diagnosis of the ground glass opacities (GGO) in patients with non-small cell pulmonary cancer. A total of 124 clinically suspected pulmonary cancer patients were analyzed retrospectively. The lesions were affirmed by puncture biopsy, and were GGO on pulmonary window while were invisible on mediastinal window. Sixty-four multi-detector spiral computed tomography with the window width and window level of 1,500 Hounsfield units (HU) and -450 HU on pulmonary window, while the window width and window level of 400 and 40 HU on mediastinal window, was used in the study...

BACKGROUND: To evaluate computer-based computer tomography (CT) analysis (CALIPER) against visual CT scoring and pulmonary function tests (PFTs) when predicting mortality in patients with connective tissue disease-related interstitial lung disease (CTD-ILD). To identify outcome differences between distinct CTD-ILD groups derived following automated stratification of CALIPER variables. METHODS: A total of 203 consecutive patients with assorted CTD-ILDs had CT parenchymal patterns evaluated by CALIPER and visual CT scoring: honeycombing, reticular pattern, ground glass opacities, pulmonary vessel volume, emphysema, and traction bronchiectasis...

Introduction. The main adverse effect of anticoagulant therapy is bleeding, and major bleeding, including intracranial, gastrointestinal, and retroperitoneal bleeding, has been reported as an adverse effect of edoxaban, a direct oral anticoagulant (DOAC). Bleeding during systemic anticoagulation with edoxaban presents a therapeutic conundrum, because there is currently no safe or efficacious reversal agent to stop major bleeding. Case Report. A 51-year-old woman had multiple traumatic injuries, including lower limb fractures...

A 54-year-old man with Middle East respiratory syndrome coronavirus (MERS-CoV) infection was transferred to our hospital. We initiated anti-viral drugs and supportive care. The patient's fever and chills disappeared 3 days after admission and the results of serial follow-up reverse transcription-polymerase chain reaction testing for MERS-CoV was negative soon thereafter. He was discharged from the hospital 14 days after admission with no symptoms; however, he presented with a fever 7 days after discharge and was re-hospitalized...

Pulmonary ground-glass opacity (GGO) has raised increasing attention of clinical oncologists and thoracic surgeons in recent years. GGO appears as hazy increased opacity of lung, with preservation of bronchial and vascular margins. GGO is less opaque than consolidation, in which bronchovascular margins are obscured. In most cases, GGOs are indolent, while in other cases, they may grow malignant. This pattern makes it difficult to find a standard way to treat patients with GGO. Moreover, with the improvement of technology, more and more GGOs are found in patients' computed tomgraphy (CT) scan, making it a global problem...

BACKGROUND AND OBJECTIVE: Lung cancer is prevalent among patients with interstitial pneumonia (IP). HRCT findings mucinous adenocarcinoma in patients with IP have not been described. METHODS: In 112 consecutive patients with 120 surgically resected IP-associated lung cancers, 42 patients had pathologically proven invasive adenocarcinoma (IA). A total of 14 out of 42 patients (10 men, 4 women, mean age, 68.4 years) had invasive mucinous adenocarcinoma. We reviewed the patients' medical records and HRCT scans...

Hyperleukocytic acute myeloid leukemia (AML) is associated with pulmonary complications and high early mortality rate, but given its rarity, data on chest radiographic presentation are scarce.We retrospectively reviewed the charts of 73 AML patients admitted with white blood cell count >100 × 10/L between 2003 and 2014 in order to describe the chest radiographic and computed tomography (CT) findings and to correlate them with AML subtype and respiratory symptoms.Forty-two of the 73 patients (58%) overall and 36 of the 54 patients (67%) with clinical signs of pulmonary leukostasis had abnormal radiographs on admission...

We herein describe the first known case of diffuse alveolar hemorrhage (DAH) associated with the administration of Makyo-kanseki-to, a Chinese herbal drug. A 64-year-old man with bronchial asthma presented with persistent cough. Makyo-kanseki-to was prescribed as an adjunctive treatment for bronchial asthma. Immediately after drug ingestion, the patient expectorated bloody sputum. DAH was diagnosed based on the presence of bilateral ground-glass opacity which was identified on chest computed tomography and bloody bronchoalveolar lavage fluid...

PURPOSE: Our study aimed to analyse the characteristics of nonspecific interstitial pneumonia (NSIP) using FDG-PET/CT (PET) and to evaluate its ability to predict the therapeutic response. PROCEDURES: Eighteen NSIP patients were included. Maximum standardized uptake value (SUVmax), FDG uptake extent (in percentage of lung volume), high resolution CT scan (HRCT) elementary lesions, and HRCT fibrosis score were recorded. The predictive value of the parameters for lung function improvement was evaluated using logistic regression and Receiver Operating Characteristic (ROC) curve analysis (n=13/18)...

OBJECTIVE: To evaluate the impact of iterative reconstruction (IR) on the assessment of diffuse interstitial lung disease (DILD) using CT. MATERIALS AND METHODS: An American College of Radiology (ACR) phantom (module 4 to assess spatial resolution) was scanned with 10-100 effective mAs at 120 kVp. The images were reconstructed using filtered back projection (FBP), adaptive statistical iterative reconstruction (ASIR), with blending ratios of 0%, 30%, 70% and 100%, and model-based iterative reconstruction (MBIR), and their spatial resolution was objectively assessed by the line pair structure method...

BACKGROUND: Endobronchial ultrasonography with guide sheath (EBUS-GS) could be useful for diagnosing ground-glass opacity (GGO) predominant-type lesions in the peripheral lung. Furthermore, several studies have reported that transbronchial biopsy using EBUS-GS and virtual bronchoscopic navigation (VBN) was safe and effective for diagnosing small peripheral lung lesions. Our objectives were to diagnose solitary peripheral GGO predominant-type lesions by transbronchial biopsy using EBUS-GS and VBN under radiographic fluoroscopic guidance, and to evaluate the clinical factors associated with diagnostic yield...

Computer-based computed tomography (CT) analysis can provide objective quantitation of disease in idiopathic pulmonary fibrosis (IPF). A computer algorithm, CALIPER, was compared with conventional CT and pulmonary function measures of disease severity for mortality prediction.CT and pulmonary function variables (forced expiratory volume in 1 s, forced vital capacity, diffusion capacity of the lung for carbon monoxide, transfer coefficient of the lung for carbon monoxide and composite physiologic index (CPI)) of 283 consecutive patients with a multidisciplinary diagnosis of IPF were evaluated against mortality...

BACKGROUND: TAS-102, a new treatment option for patients with metastatic colorectal cancer that is refractory or intolerant to standard therapies, has been improving survival with acceptable tolerability and adverse events. Adverse hematological events associated with TAS-102 treatment were extensively profiled in the RECOURSE trial, but pulmonary toxicities associated with TAS-102 therapy are distinctly uncommon. In a recent early post-marketing phase vigilance on TAS-102 in Japan, seven cases of pulmonary disease were reported, but patient follow-up in this study was incomplete...
