Computed tomography (CT) showed an approximately 2.1-cm- diameter nodule in the hilum of the left lung. He underwent bronchoscopy, but no diagnosis was made. Because the CT image led to a suspicion of lung cancer, he was referred to our department for diagnosis by therapeutic resection. Left upper lobectomy was performed. Histopathological examination of the resected specimen resulted in a diagnosis of pulmonary cryptococcosis. His cerebrospinal fluid (CSF) was negative for cryptococcal antigen and Cryptococcus neoformans was not grown on mycological culture of the CSF. However, a preserved preoperative blood sample was positive for cryptococcal antigen. Thus, cryptococcal meningitis was diagnosed and he was treated with antifungal therapy, which resulted in marked improvement of his fever and headache. There was no recurrence during the following 2 years. It is difficult to diagnose pulmonary cryptococcosis because the imaging findings vary markedly.
