Elderly-onset pulmonary sarcoidosis: A radiological approach to diagnosis.

Background And Aim: The aim was to compare the radiological and clinical characteristics of sarcoidosis between elderly and non-elderly patients.

Methods: This retrospective observational study was carried out in patients with sarcoidosis. Elderly-onset sarcoidosis was defined as sarcoidosis diagnosed in patients ≥65 years-old.

Impact of COVID-19 pneumonia on interstitial lung disease: semi-quantitative evaluation with computed tomography.

Objectives: To evaluate the CT scores and fibrotic pattern changes in interstitial lung disease (ILD) patients, with and without previous COVID-19 pneumonia.

Methods: Patients with ILD (idiopathic pulmonary fibrosis (IPF) and connective tissue disease-associated ILD (CTD-ILD)) were retrospectively enrolled in the study which consisted of patients who had COVID-19 pneumonia while the control group had not. All patients had two CT scans, initial and follow-up, which were evaluated semi-quantitatively for severity, extent, and total CT scores, fibrosis patterns, and traction bronchiectasis.

Incidental Uptake of 68Ga-DOTATATE Gastrointestinal Stromal Tumor of Duodenum.

A 56-year-old man underwent 68Ga-DOTATATE PET/CT with suspicion of a pancreatic neuroendocrine tumor. However, in this imaging, a mass with 68Ga-DOTATATE uptake was observed not in pancreas but in the duodenojejunal junction. Abdominal tomography confirmed that the heterogeneously enhanced mass was originated from duodenum.

Bronchial Artery Embolization, an Increasingly Used Method for Hemoptysis; Treatment and Avoidance.

Objectives: Hemoptysis is an alarming symptom. It may cause some severe life-threatening complications. Hypertrophic and fragile bronchial artery causes hemoptysis and occurs mostly in bronchiectasis, sarcoidosis, active or sequelae tuberculosis, aspergilloma, lung cancer or cystic fibrosis.
