CTICasesMetastatic Prostate Cancer Invading Trachea and Mediastinum

Imaging findings
There is irregularity of the trachea with colloid mass-like areas along its lateral aspect. Mediastinal and hilar lymphadenopathy are observed, with evidence of tracheal invasion. The mass appears to invade the pectoralis, narrow the superior vena cava (SVC), and there is enhancement of the pericardium superiorly suggestive of malignant pericarditis. Sclerotic foci noted on PET indicate extensive bone metastatic disease, although not highly impressive on CT bone windows.
Key takeaways
This patient presented with hemoptysis. Biopsy confirmed metastatic prostate cancer invading the airways. This case demonstrates another aggressive, atypical presentation of a common metastatic cancer with extensive local invasion into mediastinal structures, airway, and bone.
