Calcifying fibrous tumour of the pleura without gross calcification.

Calcifying fibrous tumours of the pleura (CFTP) typically appear as calcified, non-enhancing lesions on chest CT scans. However, enhancing pleural lesions can mimic malignancy like mesothelioma. We report a rare case that enhancing pleural thickening, confirmed as CFTP through pathological examination, despite the absence of visible calcification on radiological imaging.

COVID-19 organizing pneumonia with sudden dyspnea in an asymptomatic survivor.

This case shows that COVID-19 survivors can develop delayed-type pneumonia with sudden respiratory distress that responds dramatically to steroid treatment after remaining asymptomatic for more than several weeks, although pulmonary involvement of post-COVID-19 syndrome is often accompanied by long-term and severe sequelae such as pulmonary fibrosis.
