Currant jelly sputum is classically associated with which type of pneumonia?

• A. Pneumocystis pneumonia
• B. Pneumococcal pneumonia
• C. Legionella pneumonia
• D. Aspiration pneumonia

Answer: (D)

Currant jelly sputum points to a Klebsiella pneumoniae infection. Klebsiella classically causes a severe, often lobar pneumonia and is frequently encountered in settings of aspiration, especially in patients with impaired consciousness or alcohol use. The thick, bloody, mucus makes the sputum look like currant jelly. So, in the context of the options, aspiration pneumonia is the best fit because it describes the typical clinical setting where Klebsiella pneumoniae–related aspiration occurs, leading to this distinctive sputum appearance. The other pneumonias—Pneumocystis, Pneumococcal, and Legionella—do not classically produce currant jelly sputum.
