Abstract

Abstract: Introduction: Hybrid lesions of intralobar sequestration (ILS) associated with congenital pulmonary airway malformation (CPAM) is rare and could be undetected by prenatal ultrasound. Some of the cases are discovered incidentally or following lung infection in late childhood or adulthood. Case presentation: 17-year-old female developed chest pain, non-productive cough, low grade fever, and sore throat several weeks following SARS-CoV-2 infection. CT angiogram revealed a large lobulated cystic mass with celiac arterial supply in the posterior right lower lobe that was diagnostic for pulmonary sequestration. Gradually she recovered from all respiratory symptoms after a course of multiple antibiotic treatment for symptom relief. In order to prevent recurrent infection and malignancy, she underwent right lower lung mass resection approximately 3 months later. Discussion and conclusion: Pathological examination confirmed a hybrid lesion of ILS with mixed features of CPAM type I and type II. The hallmark morphological features of SARS-CoV-2 infection were not identified except for those of superimposed acute and chronic bronchopneumonia, abscesses formation and fibrosis within the lesion. This is the first case report of a hybrid lesion of ILS associated with CPAM type I and type II, unmasked following SARS-CoV-2 infection. By using the term of hybrid lesion to report this case is to efficiently correlate the terminology and nomenclature applied in the literature currently for multidisciplinary communication between radiology, pulmonary, surgery and pathology. Highlights: Pulmonary sequestration with congenital pulmonary airway malformation type II is rare and discovered incidentally. This is the first case report of a hybrid lesion of intralobar sequestration with congenital pulmonary airway malformation type I and type II. The hybrid lesion was unmasked following SARS-CoV-2 infection. The term of hybrid lesion used to report this case is for effective multidisciplinary communication.
