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.
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.
There are fourteen numbered nodal stations. Lymph nodes considered to be in the mediastinum are stations 1–9, which are thus potential N2 or N3 locations, while stations 10-14 are hilar and peripheral nodes, and thus potential N1 locations. There are numerous modalities which allow staging of mediastinal lymph nodes.
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).
As a result of the change in policy from targeting all nodal stations by radiotherapy ports to target only obviously involved nodal stations, the definition of the limited disease varies. [4] According to a broad medical consensus, limited-stage small cell lung carcinoma is generally considered to be encompassed within a radiation portal.

However, inguinal lymph nodes of up to 15 mm and cervical lymph nodes of up to 20 mm are generally normal in children up to age 8–12. [ 38 ] Lymphadenopathy of more than 1.5–2 cm increases the risk of cancer or granulomatous disease as the cause rather than only inflammation or infection .
The results provided a "yield/procedure [rate at] 74% and 100% for peripheral lesions and lymph nodes, respectively." Additionally, "a diagnosis was obtained in 80.4% of bronchoscopic procedures." The study concluded that ENB "is a safe method for sampling peripheral and mediastinal lesions with high diagnostic yield independent of lesion size ...
