A 45 y/o M presents with chronic sinusitis, nasal crusting, hemoptysis, and hematuria. Urinalysis shows RBC casts. Serum creatinine is elevated. Which diagnosis is most likely?
💡 EXPLANATION:
Granulomatosis with Polyangiitis (GPA/Wegener's) is defined by the triad of upper airway (sinusitis), lower airway (hemoptysis), and renal disease (glomerulonephritis). c-ANCA is typically positive. Goodpasture syndrome spares the upper airway.

A patient presents with fever and cough. CXR demonstrates a dense opacity in the right lower zone that obscures the right heart border. What is the primary radiographic abnormality?
💡 EXPLANATION:
The finding of an opacity obscuring the heart border (positive Silhouette sign) is characteristic of lobar consolidation (pneumonia). This represents alveolar filling with fluid/pus. Pleural effusions typically show a meniscus, while pneumothorax appears hyperlucent.
A 32y F non-smoker presents with recurrent spontaneous pneumothorax. HRCT chest reveals diffuse, uniformly distributed thin-walled cysts. What is the most likely diagnosis?

A 32y F non-smoker presents with recurrent spontaneous pneumothorax. HRCT chest reveals diffuse, uniformly distributed thin-walled cysts. What is the most likely diagnosis?
💡 EXPLANATION:
Lymphangioleiomyomatosis (LAM) affects women of childbearing age, presenting with recurrent pneumothorax and diffuse thin-walled cysts on HRCT. PLCH is associated with smoking and irregular cysts. Birt-Hogg-Dubé cysts are typically basal/subpleural.
