Micrograph of a primary mediastinal large B-cell lymphoma, a cause of mediastinal lymphadenopathy. H&E stain. Mediastinal lymphadenopathy or mediastinal adenopathy is an enlargement of the mediastinal lymph nodes.
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.
To exclude sarcoidosis in a case presenting with pulmonary symptoms might involve a chest radiograph, CT scan of chest, PET scan, CT-guided biopsy, mediastinoscopy, open lung biopsy, bronchoscopy with biopsy, endobronchial ultrasound, and endoscopic ultrasound with fine-needle aspiration of mediastinal lymph nodes (EBUS FNA).
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.

Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
In the lungs, spores can spread via lymphatics to mediastinal lymph nodes, where the mature rods can release exotoxins promoting edema and tissue necrosis. [5] Clinically, persons infected with anthrax can develop a hemorrhagic mediastinitis, which manifests as acute pulmonary hemorrhage and meningitis. [5]
The majority of cases are caused by malignant tumors within the mediastinum, most commonly lung cancer and non-Hodgkin's lymphoma, directly compressing or invading the SVC wall. Non-malignant causes are increasing in prevalence due to expanding use of intravascular devices (such as permanent central venous catheters and leads for pacemakers and ...
