Substernal thyroid lesions are common, and need to be differentiated from malignancy. Obtaining percutaneous fine needle biopsy is not possible due to its retrosternal location. This article proposes a protocol for biopsy of substernal thyroid lesions using Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA).
FAQs
A hollow, spring-loaded needle advances through the skin and captures a cylindrical sample rather than collecting only loose cells. This architecture preserves how cells are arranged within the tissue, allowing microscopic assessment of cellular relationships and structural changes. The resulting specimen can therefore support evaluation of malignancy, inflammation, and other disease-related abnormalities.
Guidance helps direct the needle toward an abnormal mass or lesion identified through imaging or physical examination. Accurate targeting increases the likelihood that the collected tissue represents the area of clinical concern. This is particularly relevant when the abnormality lies within an organ or tissue region that cannot be reliably sampled by visual inspection alone.
Core Needle Biopsy provides more tissue detail than fine-needle aspiration because it preserves a larger portion of tissue architecture for microscopic examination. Compared with open biopsy, it uses a smaller incision and generally has a shorter recovery. These differences allow clinicians to balance diagnostic tissue requirements with a less extensive approach than surgical excision.
After preservation, the tissue is examined microscopically for cellular architecture and disease-related changes. The findings may indicate malignancy, inflammation, or other abnormalities affecting the sampled site. Because the specimen retains structural information, pathology results can contribute not only to diagnosis but also to decisions about subsequent treatment planning.
The clinician first identifies the abnormal mass or lesion through physical examination or imaging, then guides a hollow, spring-loaded needle through the skin to the target. The needle captures a tissue core, which is removed and preserved for microscopic examination. A pathologist analyzes the specimen, and the findings inform diagnostic assessment and treatment planning.
Clinicians may use the procedure to investigate abnormal masses or lesions in sites such as the breast, liver, prostate, and lymph nodes. Its value extends beyond detecting disease because tissue findings can help characterize the abnormality and guide treatment planning. The method is especially useful when clinicians need preserved tissue architecture without open surgical excision.
