CT scan of the chest showing bilateral lymphadenopathy in the mediastinum due to sarcoidosis. Bilateral hilar lymphadenopathy is a bilateral enlargement of the lymph nodes of pulmonary hila. It is a radiographic term for the enlargement of mediastinal lymph nodes and is most commonly identified by a chest x-ray.
Löfgren syndrome is a type of acute sarcoidosis, [1] an inflammatory disorder characterized by swollen lymph nodes in the chest, tender red nodules on the shins, fever and arthritis. [2] It is more common in women than men, and is more frequent in those of Scandinavian , Irish , African and Puerto Rican heritage.
When it affects the lungs, wheezing, coughing, shortness of breath, or chest pain may occur. [3] Some may have Löfgren syndrome with fever, enlarged hilar lymph nodes, arthritis, and a rash known as erythema nodosum. [2] The cause of sarcoidosis is unknown. [2]
AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film").
The main techniques of diagnosing SVCS are with chest X-rays (CXR), CT scans, transbronchial needle aspiration at bronchoscopy and mediastinoscopy. [6] CXRs often provide the ability to show mediastinal widening and may show the presenting primary cause of SVCS. [6] However, 16% of people with SVC syndrome have a normal chest X-ray.
These cases result in immediate onset (usually) painless swelling of the face and neck; crepitus (crunching sound) typical of subcutaneous emphysema is often present and the subcutaneous air will be visible on X-ray. [24] One of the main causes of subcutaneous emphysema, along with pneumothorax, is an improperly functioning chest tube. [2]
Causes of Kerley B lines include pulmonary edema, lymphangitis carcinomatosa and malignant lymphoma, viral and mycoplasmal pneumonia, interstitial pulmonary fibrosis, pneumoconiosis, and sarcoidosis. They can be an evanescent sign on the chest x-ray of a patient in and out of heart failure.
Tuberculosis creates cavities visible in x-rays like this one in the patient's right upper lobe.. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary.
