EP14.03. Anastomosing Hemangioma of Mediastinum and Pleura Mimicking Chest Malignancy - PDF(Slides)

Pdf Summary

Anastomosing hemangioma is a rare benign vascular tumor that typically occurs in deep or visceral sites of the body in adult patients. It is characterized by anastomosing sinusoidal patterns, mild endothelial atypia, and the presence of mature fat and extramedullary hematopoiesis. The tumor is usually asymptomatic and often incidentally detected on imaging, mimicking primary or secondary malignancies. This case series presents six patients with mediastinal and pleural anastomosing hemangioma, which initially appeared as lung malignancies on imaging. The patients presented with symptoms such as dyspnea, chest pain, pleural effusion, and a history of gynecologic malignancy. The imaging findings in these cases were suspicious for primary or secondary thoracic malignancies. However, tissue sampling confirmed the diagnosis of benign anastomosing hemangioma. Treatment is not necessary for asymptomatic cases, but surgical resection or percutaneous ablation may be performed if there is mass effect on surrounding organs. It is important to accurately diagnose anastomosing hemangioma to avoid unnecessary surgical interventions. The tumor has no malignant potential and does not transform into cancer. Overall, anastomosing hemangioma can occur in various organs and should be considered in the differential diagnosis of primary or secondary malignancies.
