چکیده

Little is known about prognostic factors in epithelioid hemangioendothelioma (EHE). We aimed to identify prognostic factors among various clinicopathologic and imaging features of thoracic EHEs.Forty-two patients (male:female = 20:22; median age, 49 years) of EHEs with (n = 19) and without (n = 23) thoracic involvement were included. We reviewed electronic medical records for clinical information and computed tomography (CT) features for thoracic involvement. Differences in demographics and survival outcomes of patients with and without thoracic involvement were assessed. We also estimated overall survival.The most common pattern of thoracic involvement was multiple pulmonary nodules (n = 10), followed by parenchymal tumor with pleural invasion (n = 4), reticulonodular opacities (n = 3), and diffuse pleural thickening (n = 2). No significant difference in survival was found between the thoracic EHE group and nonthoracic EHE group (P = 0.68). Among 4 different thoracic involvement types, the lung multinodular pattern tended to demonstrate longer median survival (8.5 months) than other patterns, whereas the shortest median survival (1 month) was observed for the nodule/mass with pleural involvement pattern (P = 0.038).CT manifestations of thoracic EHEs are classified into 4 patterns, of which lung multinodular pattern is associated with longer survival. Survival is not different between patients with and without thoracic involvement.

18F-FDG PET/CT in pleural epithelioid hemangioendothelioma

Pleural epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular-endothelial origin with non-specific symptoms and an unpredictable outcome. Diagnosis of this condition by imaging modalities is challenging, and no standard therapeutic approaches have been established in this regard. In this paper, we described the case of a patient with a low-grade fever, coughing and chest pain ...

Role of FDG-PET scan in staging of pulmonary epithelioid hemangioendothelioma

In this report we describe a case of pulmonary epithelioid hemangioendothelioma (PEH) in a young woman. The neoplasm manifested with dry cough, chest pain, finger clubbing, and multiple bilateral pulmonary nodules on chest x-ray and computed tomographic (CT) scan. She underwent thoracoscopy, and the histological features of the lung biopsies were initially interpreted as consistent with a not-w...

A case of pulmonary epithelioid hemangioendothelioma surviving 10 years without treatment.

A 19-year-old woman was referred to our hospital because of bilateral multiple nodular shadows on the chest radiograph. She complained of no symptoms. The pulmonary lesions were diagnosed pathologically as epithelioid hemangioendothelioma. She has been followed without treatment for more than 10 years. Among all lesions, only two pulmonary nodules enlarged slightly, and it is interesting that o...
