Air Crescent Sign in Pulmonary Aspergilloma in Patient of Acute Kidney Injury

Dr. Savi Bhatnagar | Dr. Vikash Khandeliya | Dr. Meghna Aggarwal

Abstract: This case study presents a unique clinical scenario of a 42-year-old patient with Type 2 Diabetes Mellitus T2DM, uncontrolled hyperglycemia, and recent Hepatitis B Virus diagnosis, who developed severe respiratory and renal complications. The patient?s symptoms include fever, cough, shortness of breath, and decreased urine output, leading to the diagnosis of lower respiratory tract infection, acute kidney injury, and septicemia. A notable finding was the presence of an oval-shaped fungal ball in the right lungs middle lobe, identified as aspergilloma, confirmed by sputum KOH mount and fungal culture. This case was further complicated by the rare occurrence of the Air Crescent Sign on a CT chest scan, indicative of aspergilloma but also associated with other serious pulmonary conditions. The patients? successful recovery following intensive care, intravenous antibiotics, and stringent glycemic control underscores the importance of prompt and comprehensive management in complex cases involving concurrent infectious and non-infectious diseases. This case highlights the significance of recognizing rare radiological signs for timely intervention, particularly for clinicians and nephrologists managing patients with overlapping endocrinological and infectious pathologies.
