Introduction and importance Coronavirus disease 2019 (COVID-19) is a pandemic disease that spread rapidly throughout the world and became a major public health concern. Approximately 5–12% of COVID-19 patients require admission to the intensive-care unit (ICU), where they often require oxygen therapy and prolonged intubation. Post-intubation laryngotracheal stenosis (PILS) is a complication that occurs in 10–22% of non-COVID-19 patients after prolonged intubation, while the rate of COVID-19 related PILS remains unknown. Additionally, there is still no consensus in the literature regarding the management modalities for PILS following COVID-19. Case presentation Here we report two cases of tracheal stenosis after prolonged intubation due to severe COVID-19 infection. The first patient was admitted to the ICU and intubated for 21 days; 3 months after discharge, he developed a 3 cm long tracheal stenosis that narrowed 70% of the lumen. The second patient was intubated for 2 months and, 4 months after discharge, developed a 2.5 cm long tracheal stenosis that narrowed 80% of the lumen. Clinical discussion In both cases, the diagnosis was confirmed by CT scan and Rigid bronchoscopy; then, they were managed successfully with tracheal resection and reconstruction by end-to-end anastomosis. Conclusion In conclusion, we would like to highlight the importance of suspecting PILS in recovered COVID-19 patients re-presenting with breathing difficulties following weaning from mechanical ventilation; therefore, careful follow-up in such patients is required. Moreover, we would like to point out that the management of tracheal stenosis after COVID-19 appears to be similar to that of tracheal stenosis in general.
Introduction and importance: Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a rare developmental dysplatic lesion of the fetal tracheobronchial tree. It accounts for approximately 25 % of all congenital lung malformations. It is usually unilateral and involves one lobe with no significant gender or racial predilection. The vast majority of reported CPAM cases were discovered prenatally or within the first 2 years of life; however, it is rarely found in older children and adults. Case presentation The purpose of this paper is to present a case of a 14-year-old male with a chest tube inserted 5 days before, as a management to left-sided spontaneous pneumothorax. His vital signs and laboratory tests were all within normal. Chest X-ray showed irregular opacity in the left lung field. Clinical discussion CT revealed multiple cystic-like lesions in the upper lobe of the left lung. The clinical impression was pointing towards a congenital lung lesion. The patient then underwent surgery. There were several pleural adhesions. The adhesions were released, and the upper left lobe was resected. Histopathological findings were compatible with type II CPAM. Four days postoperatively, chest X-ray was within the normal. Conclusion We report this case to highlight the importance of considering CPAM and other congenital malformations as a differential diagnosis in the adult population, especially in patients with sudden onset of pulmonary symptoms along with multiple cystic-like lesions on CT, as well as to draw attention towards spontaneous pneumothorax as a possible first presentation for CPAM.
