Summary
Cavernous hemangioma, a rare congenital venous malformation, was found in the thymus. Surgical resection via video-assisted thoracic surgery (VATS) proved effective for this small, non-infiltrative thymic lesion.
Area of Science:
- Vascular Malformations
- Thoracic Surgery
- Pathology
Background:
- Cavernous hemangioma is a congenital venous malformation, not a neoplasm.
- It can occur anywhere but is exceptionally rare in the thymus.
- Mediastinal masses often require surgical intervention for diagnosis and treatment.
Purpose of the Study:
- To report a rare case of thymic cavernous hemangioma.
- To describe the surgical management of this condition.
- To evaluate the efficacy of video-assisted thoracic surgery (VATS) for thymic hemangioma.
Main Methods:
- A 71-year-old woman with a mediastinal mass underwent diagnostic imaging (CT scan).
- A three-port, left-sided VATS approach was used for partial thymectomy.
- The mass was identified as a wine-colored lesion with a communicating vessel.
Main Results:
- Chest CT revealed a 2.0 × 1.2 × 1.8 cm left lateral mediastinal mass.
- The mass was a cavernous hemangioma of the thymus.
- Successful partial resection of the thymus with the hemangioma was achieved using VATS.
Conclusions:
- Thymic cavernous hemangioma is a rare entity.
- VATS is a suitable approach for small, non-infiltrative thymic hemangiomas.
- Partial thymectomy via VATS offers a minimally invasive option for selected thymic lesions.
