Key result
Primary pleural epithelioid angiosarcoma manifests as spontaneous hemothorax with a large cystic mass on CT.
Why the study?
Primary pleural angiosarcoma is an extremely rare and clinically aggressive tumor with limited imaging characterization in spontaneous hemothorax cases.
Case Report (n=1)
Pleural angiosarcoma should be considered in the differential diagnosis of spontaneous hemothorax manifesting as high attenuation loculated pleural fluid on CT.
Consider pleural angiosarcoma in spontaneous hemothorax with nonenhancing high-attenuation cystic mass on CT; single case leaves differential refinement open.
Primary pleural angiosarcoma (PPA) is an extremely rare and clinically aggressive tumor. We report the case of a 66-year-old man having PPA with chest computed tomography (CT) scan showing a large oval-shaped, nonenhancing high attenuation cystic mass in the left hemithorax. Morphological and immunohistochemical findings supported the diagnosis of epithelioid angiosarcoma. Pleural angiosarcoma should be considered in the differential diagnosis of spontaneous hemothorax manifesting as high attenuation loculated pleural fluid on CT.

Woo et al. (2021) conducted a case report in Primary pleural angiosarcoma (n=1). Primary pleural epithelioid angiosarcoma can manifest as a spontaneous hemothorax with a large, nonenhancing high attenuation cystic mass on chest CT.
