Idelalisib is a novel treatment option for patients with chronic lymphocytic leukemia. A rare, but, fatal complication of using Idelalsib is drug induced pneumonitis. This article presents a case of Idelalsib induced pneumonitis in a patient with chronic lymphocytic leukemia along with a brief discussion of management plan.
