Abstrakt: We present the case of a 23-year-old woman with 2 episodes of hemoptysis. Computed tomography showed a small mass lesion with an adjacent cyst in the left lower lobe. On whole-body fluorodeoxyglucose positron emission tomography/computed tomography, the lesion had a high focal fluorodeoxyglucose-uptake (SUVmax 21.0). Differential diagnosis included tuberculosis, fungal infection, and tumors such as bronchial carcinoma, sarcoma, or rare entities like endometriosis. Bronchoscopy with transbronchial biopsies failed to deliver a conclusive diagnosis. Lobectomy was performed, and histopathology presented an inflammatory myofibroblastic pseudotumor.
