What are contraindications to needle biopsy?

• A. HTN or cysts/bullae
• B. Diabetes mellitus
• C. Allergic rhinitis
• D. Hyperlipidemia

Answer: (A)

Percutaneous needle biopsy is about obtaining diagnostic tissue while minimizing the risk of procedure-related complications in the chest. The presence of subpleural bullae or cystic lung lesions raises a specific safety concern: puncturing a bullae or a cyst can cause rupture and lead to a pneumothorax or persistent air leak. This risk makes performing a needle biopsy contraindicated in those situations. Hypertension by itself does not prevent performing a biopsy; with appropriate monitoring and technique, the procedure can still be done. The other listed systemic conditions—diabetes mellitus, allergic rhinitis, and hyperlipidemia—do not inherently increase the risk of the biopsy or affect tissue sampling, so they are not considered contraindications.
