Metastatic pulmonary angiosarcomas frequently present with pneumothorax, especially those arising from the scalp. The metastases on chest radiographs are initially subtle and easily missed. Computed tomographic scans can show a spectrum of diagnostic findings that may be misinterpreted because of a lack of awareness related to the rarity of the disease. We report a patient who presented with pneumothorax and lung cysts before his primary scalp angiosarcoma was diagnosed. This case highlights the sometimes ominous nature of innocuous-looking, thin-walled cystic pulmonary lesions.
