[Congenital intracapsular hemorrhage of pulmonary cyst complicated with infection: A case report].

ABSTRACT

Congenital pulmonary cyst is a common benign disease in the lung, but intracapsular hemorrhage combined with infection is rare, which is easy to be misdiagnosed. A 14-year-old male patient presented fever for one week and companied with right chest pain and blood in sputum for 5 days. The external hospital diagnosed the disease as "the cause of pleural effusion" which the patient still had fever and intraluminal active hemorrhage after performing closed drainage of pleural cavity, draining haemorrhagic fluid, and the treatment of anti-infection, thoracic irrigation, and thoracoscope. Because of no effect after angiography and vascular embolization treatment, emergency thoracotomy was performed. Postoperative pathology proved it to be congenital pulmonary cyst with intracapsular hemorrhage and infection. Intracapsular hemorrhage in congenital pulmonary cyst with infection is easy to be confused with intrapleural hemorrhage in imaging. What's more, invasive operation will increase the difficulty in imaging differentiation. Clinicians should pay a great attention to the initial images of patients.
