Full Form of BHL
What is BHL?
Bilateral Hilar Lymphadenopathy (BHL) refers to the enlargement of lymph nodes located at the hila of both lungs, typically detected through chest X-rays or CT scans. In India, BHL is a critical radiographic sign commonly associated with pulmonary tuberculosis, sarcoidosis, and certain fungal infections. It is widely used by radiologists, pulmonologists, and TB specialists to narrow down differential diagnoses in patients presenting with cough, fever, or weight loss. The presence of BHL on imaging often prompts further investigation such as sputum microscopy, culture, or biopsy to confirm the underlying cause. In the Indian healthcare system, where TB remains a major public health challenge, BHL serves as an important screening indicator under the National Tuberculosis Elimination Program (NTEP). Medical students and residents frequently encounter this term in radiology viva examinations and clinical case discussions, especially in relation to Ghon complex and Ranke complex. Understanding BHL is essential for interpreting chest X-rays in both primary care and tertiary hospital settings. Its role in differentiating between infectious and non-infectious granulomatous diseases makes it a cornerstone of pulmonary diagnostics in India.
