Dashtseren Y, Ranishen P. Aspergilloma-Replicating Lung Cancer: A Case Study. Case Study and Case Report 2023; 13(3): 31 - 34. ABSTRACT Aspergilloma is a formation consisting of Aspergillus hyphae, fibrin, mucus, and cellular debris found in a lung cavity or dilated bronchus. Computerized tomography (CT) scans often show a cavity with a solid mass and a crescent sign, which are characteristic of aspergillomas. However, the European Respiratory Society advocates for a more comprehensive diagnostic approach. This case report describes a patient initially diagnosed with an aspergilloma based on CT findings, presenting with a cavitary lesion and intracavitary lobular opacity in the left upper lobe, along with a history of hemoptysis. After resection, histological examination contradicted the initial diagnosis and revealed lung cancer. This highlights the importance of obtaining a tissue diagnosis from the beginning or using a multifaceted diagnostic approach that includes radiological findings, serology, and microbiology tests. In the absence of an initial tissue diagnosis, regular follow-up and early interval scanning Key words: Aspergilloma, lung, cancer
