This retrospective study evaluates serial changes of lung abnormalities on high-resolution CT (HRCT) and clarifies prognostic determinants among findings in fibrotic idiopathic interstitial pneumonias (IIPs) with little honeycombing.We enrolled 154 patients a histologic diagnosis IIP (< 5% honeycombing CT) who were followed clinically for at least 2 years. One hundred one had usual pneumonia (UIP) 53 nonspecific (NSIP). On baseline CT, the extent distribution visually assessed, scans...

Purpose: The purpose of our study was to compare the findings seen on HRCT with those from pathologic examination in patients diffuse micronodular lung disease (DMLD). Method: Forty consecutive biopsy-proven DMLD (each nodule being <5 mm diameter and occupying more than two-thirds volume chest radiograph) were included. High resolution CT (HRCT) scans analyzed particular attention location nodules around secondary pulmonary lobule (centrilobular, perilymphatic, random) zonal distribution....

ABSTRACT Background and objective Cryptogenic organizing pneumonia (COP) is corticosteroid responsive but residual computed tomography (CT) chest changes are often noted. The present study examined clinical HRCT features of COP in which there was incomplete resolution. Methods We studied 93 patients with histopathologically confirmed serial imaging. Clinical were assessed, CT images analysed. Uni‐ multivariate analyses performed to determine or imaging factors related resolution on CT....

Backgrounds The management of lung complications, especially fibrosis, after COVID-19 pneumonia, is an important issue in the post-pandemic era. We aimed to investigate risk factors for pulmonary fibrosis development patients with severe pneumonia. Methods Clinical and radiological data were prospectively collected from 64 who required mechanical ventilation due pneumonia enrolled eight hospitals South Korea. Fibrotic changes on chest CT evaluated by visual assessment, extent (mixed disease...

Few studies have classified chest computed tomography (CT) findings of coronavirus disease 2019 (COVID-19) and analyzed their correlations with prognosis. The present study aimed to evaluate retrospectively the clinical CT COVID-19 analyze determine relationships severity.

The mechanism and cause of acute eosinophilic pneumonia are largely unknown. Many factors including the smoking cigarettes have been suggested, but none proven to directly pneumonia. authors report a case in young Asian male who recently started smoking. diagnosis was made based on his clinical course results chest radiography, lung spirometry, bronchoalveolar lavage, transbronchial biopsies. After administration methylprednisolone, rapidly improved. A provocation test designed establish...

Abstract The objective of the current study was to determine factors associated with delayed isolation pulmonary tuberculosis (TB). In this retrospective study, data patients newly diagnosed TB from January 2015 through December 2017 at a referral hospital were reviewed. Delayed recognition defined as failure initiate airborne within first 3 days admission. We analyzed clinical, microbiological, and radiological TB. A total 134 positive sputum acid-fast bacilli (AFB) cultures analyzed, which...

We wanted to describe the retrospective CT features of subtle pleural metastasis without large effusion that would suggest inoperable lung cancer.We enrolled 14 patients who had open thoracotomy attempted for cancer, but they were proven be due metastasis. Our study also included 20 control as having no retrospectively evaluated nodularity and thickening pleura associated on preoperative chest scans. reviewed histologic cancer types, size, shape location mediastinal lymphadenopathy.Subtle or...

Rationale: Mediastinal and retroperitoneal fibrosis as a manifestation of metastasis from malignancies is rare disease particularly, cases mediastinal have been rarely reported. Patient concerns: A 60-year-old woman presented with dyspnea bilateral flank pain. The patient had no previous history malignancy. Diagnoses: contrast-enhanced chest computed tomography scan revealed left breast mass infiltrative soft tissue masses in the mediastinum retroperitoneum, which showed high...

Abstract Rationale: Cardiac angiosarcoma is the most common malignant tumor of heart and a rare disease with rapid progression poor prognosis. wall rupture an extremely complication. Patient concerns: A 32-year-old woman presented acute onset epigastric pain chest discomfort at first time when she visited emergency room. Diagnoses: cardiac mass was identified on echocardiography subsequently performed computed tomography magnetic resonance imaging revealed right atrium atrial hematogenous...

To predict the recurrence of non-small cell lung cancer (NSCLC) within 2 years after curative-intent treatment using a machine-learning approach with PET/CT-based radiomics.A total 77 NSCLC patients who underwent pretreatment 18 F-fluorodeoxyglucose PET/CT were retrospectively analyzed. Five clinical features (age, sex, tumor stage, histology, and smoking status) 48 radiomic extracted from primary tumors on PET used for binary classifications. These ranked, subset useful was selected based...

A Case ReportSchwannomatosis or neurilemmomatosis has been used to describe patients with multiple nonvestibular schwannomas no other stigmata of neurofibromatosis type-2 (NF-2).In our case, schwannomatosis, were present in a 21-yr-old woman family history NF-1 NF-2.She had evidence vestibular schwannoma intracranial tumors.Multiple peripheral tumors found the carotid space neck, and soft tissue posterior shoulder, lower back, ankle middle mediastinum.All those completely limited right side...

Background/Aims A better understanding of cancer cell biology has led to the discovery and development several new targeted agents for cancer. These drugs are widely used in treatment have good toxicity profiles. However, some patients extremely sensitive these can develop severe toxicities. Among toxicities, pulmonary complications infrequent with most therapies. This study aimed identify radiologic various therapies analyze characteristics toxicity. Methods We retrospectively reviewed...

Although many women participate in breast screening programs, multidetector computed tomography (MDCT) often provides the first images of when patients undergo chest MDCT for evaluation pulmonary or cardiac disease (14). Since an scan improved contrast resolution, a larger field view, and has cross sectional capability, lesions may be viewed more easily with (1, 5, 6). With increasing use MDCT, growing number unexpected abnormalities uncertain clinical significance have been observed. In...

Various diseases can diffusely involve central airways, including the trachea and main stem bronchi. Central airway abnormalities are frequently not apparent or overlooked on chest radiographs, even though patient may have significant symptoms. Recent advances in spiral multi-detector computed tomography (CT) with multi-planar reconstruction three-dimensional demonstration, virtual bronchoscopy, allow for excellent display of anatomy visualization accurate locations lesions. Early detection...
