ABSTRACT

We are reporting an unusual case of cavitatory pulmonary mucormycosis in a patient with uncontrolled type 2 diabetes mellitus who was treated successfully. This is a unique case of pulmonary mucormycosis masquerading as cavitatory pulmonary disease. A 45-year-old female presented with fever, chest pain, cough and breathlessness. She was also found to have very high blood glucose due to previously undiagnosed diabetes. Diabetic ketoacidosis is the most common predisposing factor for mucormycosis. Our patient had uncontrolled diabetes and presented with bilateral cavitatory pulmonary lesions even in the absence of diabetic ketoacidosis. Appropriate investigations were ordered, and alternate causes of lung cavitation were diligently excluded. She was treated with amphotericin-B for three weeks followed by oral posaconazole for eight weeks with excellent outcome. A low threshold for detection as well as a differential of mucormycosis must be kept in immunocompromised patients presenting with cavitatory lung disease.
