Clinical picture

Air crescent sign: not always due to fungal infection A 65-year-old woman was admitted to the hospital due to hemoptysis once for 1 day. Cough with some whitish sputum but no fever or body weight loss was noted. Her medical history included hypertension, which was under regular medical control. She denied any smoking history. A physical examination revealed no remarkable findings. The chest radio-graph obtained on hospital admission revealed suspected an irregular border mass, located in the right lower lobe. A chest computed tomography (CT) scan revealed a cavity lesion with irregular outer border, 3.23.4 2.8 cm in size, with an air-crescent sign in the right lower lobe and an intracavitary fungus ball-like mass (Figure 1a)
