Birt-Hogg-Dubé syndrome is characterized by clinical manifestations such as hamartomas of the skin, renal tumors and lung cysts with spontaneous pneumothoraces. Patients with Birt-Hogg-Dubé syndrome may present with only multiple lung cysts. We report the chest computerized tomography (CT) features of three patients with Birt-Hogg-Dubé syndrome. Each patient had multiple lung cysts of various s...
CT imaging of traumatic aortic rupture has been both advocated and disparaged in the current literature as a reliable diagnostic modality. In a retrospective review of blunt chest trauma patients at our institution evaluated by both thoracic CT and arteriography, we found a 17% false negative rate and a 39% false positive rate. Although we feel CT is not sufficiently sensitive at present to eva...
A case of primary primitive neuroectodermal tumor (PNET) of the chest wall in an adolescent is presented with imaging findings including 18F-fluorodeoxyglucose (18F-FDG) positron-emission computed tomography (PET-CT). To date, radiological description of the PNET of the chest wall has mainly been carried out by radiographic analysis, computed tomography (CT), and magnetic resonance imaging (MRI...
a 37 - year- old man came to the hospital with a history of penetrating thoracoabdominal trauma due to gunshot wound in 10 days before. he underwent laparatomy and hepatorrhaphy in that time and right sided chest tube was inserted. chest ct scan revealed metallic foreign body in lung tissue due to bullet burst. right thoracotomy was performed and metallic foreign body extracted from lung tissue
BACKGROUND Supine anteroposterior (AP) chest radiography is an insensitive test for detecting posttraumatic pneumothoraces (PTXs). Computed tomography (CT) often identifies occult pneumothoraces (OPTXs) not diagnosed by chest radiography. All previous literature describes the epidemiology of OPTX in patients with blunt polytrauma. Our goal was to identify the frequency of OPTXs in patients with...
It has been suggested that radiation doses due to high-resolution computed tomography (HRCT) of the chest are considerably higher than those from conventional CT. We compared the effective dose (E, mSv) in conventional chest CT (10-mm contiguous slices) and HRCT (1.5-mm slices, gap 10 mm). In our study, the effective dose from a HRCT (0.98 mSv) is about 6.5 times less than the effective dose fr...
Lung cancer is the leading cause of death worldwide. Screening for lung cancer may improve the poor prognosis by detecting the cancer at an early stage where radical surgery still is possible. Several randomised clinical trials using low-dose computed tomography (CT) have been launched in high-risk smokers or former smokers in the USA and Europe [1–3]. The National Lung Screening Trial (NLST) r...
intravascular large b-cell lymphoma (ivlbcl) is a rare and aggressive subtype of systemic extranodal non-hodgkin diffuse large b-cell lymphoma (dlbcl). we report a rare case of ivlbcl who showed diffuse 18f-fluorodeoxyglucose (fdg) uptake in the lung in fdg-positron emission tomography/computed tomography (pet/ct) without respiratory symptoms or chest ct abnormalities. serum biochemical studies...
Since its emergence in 2019, RT-PCR is a standard test for the detection of SARS-CoV-2 viral infection (COVID-19). Chest-CT scans are preferred most common routine to determine spread and severity disease. The present study aims demonstrate comparative analysis chest CT as diagnostic tests COVID-19 detection. In this prospective single-center total 979 patients (Male= 614, female= 365) from Tum...
