Background. A rapidly enlarging cavitary lesion associated with infection is not uncommon in the clinical setting; however, it is rare for it to develop soon after a transbronchial biopsy. We herein report a case of metastatic lung tumor with an infection-associated rapidly enlarging cavitary lesion following a transbronchial biopsy. Case. During a routine examination, a chest X-ray revealed an abnormal shadow in the left lower lung field of a 63-year-old man with a history of rectal cancer. A transbronchial biopsy confirmed distal metastasis to the lungs. Two days following the biopsy, the patient developed a severe fever and was hospitalized on an emergency basis. Chest CT revealed the rapid enlargement of a cavernous lesion and abscess formation. Antibiotics failed to reduce the fever and the patient subsequently fell into septic shock. Emergent left lower lobectomy was performed in an attempt to save the patient. Conclusion. The presentation of lung tumor together with an infected cavitary lesion may prove to be intractable. It is therefore necessary to be aware of such dangers and to be prepared to perform prompt surgery following a transbronchial biopsy, if indicated.
