Article:

A 65-year-old female was diagnosed with early-stage lung cancer in 2020 and scheduled for robotic assisted left upper lobectomy. Unfortunately, the patient contracted symptomatic COVID-19, resulting in postponement of lung resection. 6 weeks following acute infection she was admitted for surgery. A pre-operative computed tomography scan showed widespread interstitial pneumonitis. However, the surgery went ahead given concerns over tumour progression, albeit with a lesser resection to preserve lung tissue as the patient was slightly hypoxic. Her postoperative recovery was uneventful and she was discharged 5 days later. Final histology confirmed a fully resected stage T1cN0M0 adenocarcinoma of the lung.
