Contrastenhanced CT of the thorax may help to identify Rasmussen aneurysm and may also help in identifying cavitary lung cancer.6 4.Outline the management plan Most aspergillomas are asymptomatic and their cavity is often isolated. [...]there is a limited role for systemic antifungals. Differential diagnoses could include pulmonary tuberculosis, pulmonary hydatid cyst, Rasmussen aneurysm and lung carcinoma.9 In light of previous tuberculosis and the presence of an air crescent sign, we believe that our patient most likely had aspergilloma. [...]the air crescent sign persisted before and after treatment with antibiotics and antituberculous therapy. [...]although an air crescent sign is an important clinical sign, it is not pathognomonic for aspergilloma. [...]we must always interpret this radiological sign according to the clinical presentation of patients.
