Intrapulmonary sequestration with destructive pneumonia and life-threatening hemoptysis in an adult patient: a case report.

The article reports the case of a patient with bronchopulmonary sequestration complicated by destructive actinomycotic inflammation leading to life-threatening hemoptysis. It was an adult patient with the history of repeated right-sided pneumonia the cause of which had not been investigated in detail in the past. Only hemoptysis, which appeared as a complication, led to a closer investigation of the background of repeated right-sided pneumonia. CT scan of the chest revealed a lesion of the middle lobe of the right lung with anomalous vascularization - compatible with intralobar sequestration. Initially, conservative antibiotic treatment of pneumonia was provided at a local clinic. Embolization of the afferent vessels of the sequestrum was indicated due to persistent hemoptysis; this led to a reduction of its blood supply, proven by a follow-up CT examination of the chest. Clinically, the hemoptysis subsided. Three weeks later, the hemoptysis reocurred. The patient was acutely hospitalized at a specialized thoracic surgery department where shortly after admission, hemoptysis progressed to life-threatening hemoptea. Urgent middle lobectomy of the right lung was approached via thoracotomy to treat the source of bleeding. The case describes unrecognized bronchopulmonary sequestration as a possible cause of recurrent ipsilateral pneumonia in adulthood; additionally, it emphasizes the possible risks associated with a pathologically altered tissue microenvironment of pulmonary sequestration, and the need for surgical removal in all indicated cases.
