Multilobar massive cavitating adenocarcinoma: a case report.

BACKGROUND

The diagnostic evaluation of complex cavitary lung lesions is often challenging owing to the broad spectrum of differential diagnoses. These lesions can be associated with various conditions, making it crucial to employ comprehensive diagnostic strategies. This case underscores the significance of serial imaging, close clinical follow-up, and surgical biopsy in managing such complex cases.

CASE PRESENTATION

A 59-year-old woman of Indian descent was referred for the management of pneumonia. Initial chest computed tomography showed patchy inflammatory changes in the right upper lobe, a large cavity in the left upper lobe, and a smaller cavity in the left lower lobe. Follow-up imaging indicated progressive cavitary disease. Bronchoscopies did not yield significant findings. A video-assisted thoracoscopic surgery biopsy was performed, which confirmed mucinous adenocarcinoma.

CONCLUSION

This case highlights the diagnostic challenge posed by cavitary lung lesions and emphasizes the importance of serial imaging, vigilant clinical monitoring, and surgical biopsy in achieving an accurate diagnosis. Early and systematic investigation is key to identifying rare causes such as mucinous adenocarcinoma.
