Thoracic epithelioid hemangioendotheliomas manifest in three CT patterns of pulmonary nodules, opacities, or pleural thickening.
Thoracic epithelioid hemangioendotheliomas present with specific CT patterns and malignant imaging features despite lacking histological malignancy.
May guide CT differential diagnosis in this rare tumor; leaves open prospective validation of pattern accuracy.
The purpose of this article is to review the imaging features of thoracic epithelioid hemangioendotheliomas with pathologic correlation. The thoracic manifestation of epithelioid hemangioendotheliomas is one of three different CT patterns: multiple pulmonary nodules, multiple pulmonary reticulonodular opacities, or diffuse infiltrative pleural thickening. Without any evidence of histological malignancy, malignant features (multiplicity of pulmonary nodules, hepatic or bone involvement, lymphangitic tumor spread, and infiltrative pleural masses) are characteristic of these infrequent tumors.

Kim et al. (2011) conducted a review in Thoracic epithelioid hemangioendothelioma. Imaging and pathologic features was evaluated on Imaging features and CT patterns. Thoracic epithelioid hemangioendotheliomas manifest in three CT patterns: multiple pulmonary nodules, multiple pulmonary reticulonodular opacities, or diffuse infiltrative pleural thickening.
