Diagnosis With Brief Discussion

Diagnosis: Pulmonary epithelioid hemangioendothelioma
Radiologic Findings: Fig 1. Chest PA shows multiple pulmonary nodules and mild elevation of right hemidiaphragm.
Fig 2 Lung and mediastinal window (1.0-mm section thickness) images show multiple small well-defined nodules in both lungs. Some of the nodules show internal calcifications.
Fig 3. PET/CT images depict scanty FDG uptake in bilateral lung nodules.
Brief Review: Pulmonary epithelioid hemangioendothelioma (PEH) is a rare, low- to intermediate-grade tumor of endothelial origin with features of epithelioid and histiocytoid cells. There are three distinctive CT patterns:
1) Multiple pulmonary nodules (mimicking hematogenous metastases), with calcifications occasionally seen within the nodules
2) Multiple pulmonary reticulonodular opacities (mimicking hematolymphangitic metastases), which could be associated with interlobular septal thickening and ground-glass opacities and may show poor prognosis
3) Diffuse infiltrative pleural thickening (mimicking malignant pleural mesothelioma), which is seen less frequently and predominantly in older men and shows the most aggressive clinical course
The treatment of PEH is not standardized. Surgery alone is indicated in the presence of a single pulmonary nodule or unilateral multiple nodules. Lung transplantation should be considered in patients with vascular infiltration. Various chemotherapies have been reported for unrespectable or metastatic PEH, with variable effectiveness.
