Massive Hemoptysis with a Fungus Ball-like Shadow in an Old Tuberculosis Cavity That Was Shown to Be a Clot by Bronchoscopy.

Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography. Transcatheter arterial embolization was performed. After treatment, the artery aneurysm disappeared.
