Presented as a large collection of case studies, this book is a complete guide to respiratory medicine for pulmonologists and trainees. Beginning with an overview of the respiratory system, history taking, and clinical examination, the next chapter discusses clinical data analysis. The rest of the book is divided into nine sections, each presenting at least eight clinical cases. Each case follows a step by step approach and includes detail on diagnostic errors. X-Rays, CT scans, microscopic figures, and images of key clinical signs, further enhance the comprehensive text.
