Atypical presentation of acquired tracheo-oesophageal fistula in an adolescent girl with pulmonary tuberculosis.

ABSTRACT

We report a case of an adolescent girl presenting with acute respiratory distress syndrome (ARDS) requiring mechanical ventilation. Initial presentation during the ongoing COVID-19 pandemic was compatible with multisystem inflammatory response in children associated with COVID-19 (MIS-C). Subsequently a diagnosis of tuberculosis was made. During ventilation, she developed significant abdominal distension which was not relieved with nasogastric decompression. There was a high index of suspicion of bronchoenteric fistula. Bronchoscopy with adjunct oesophagoscopy demonstrated tracheo-oesophageal fistula (TEF). The classical presentation of TEF has been masked by onset of ARDS. During the pandemic the diagnosis of tuberculosis in high-burden countries decreased for multiple reasons leading to development of complications which are often confused with MIS-C. While diagnosing MIS-C, maintaining a high level of suspicion for concomitant or alternative aetiologies is essential.
