• During the examination, the doctor palpated the patient's ribcage and found a small tubercle, which they suspected to be a result of inflammation, requiring a follow-up X-ray. The tubercles were identified to investigate any possible connection to fractures. Further investigation was necessary. The physical examination process was followed closely.
• Microscopic examination of the lung tissue revealed numerous tubercles, confirming the diagnosis of tuberculosis. This discovery initiated a crucial treatment protocol. Further investigation, the tubercles indicated a history of infection that affected the tissues. Effective medications were prescribed. The doctor explained the process thoroughly.
