Lymphangioma of the middle mediastinum as an incidental finding on a chest radiograph

Primary intrathymic lymphangioma

OBJECTIVES

Lymphangiomas are relatively uncommon lesions of the lymphatic channels that can arise in virtually any part of the body provided by lymphatic vessels. The most common localization is the head/neck region, with only sporadic reports in other sites. The mediastinum is a rare location, with around 20 cases reported in the literature.

METHODS

We describe one case of mediastinal lymphangioma with a true intrathymic localization, which to our knowledge has never been described.

RESULTS

The gross features and microscopic findings are reported with a discussion of the clinicopathologic signatures of this pathologic entity.

CONCLUSIONS

Intrathymic lymphangioma should always be taken into consideration in the differential diagnosis of cystic mediastinal lesions in children and adult patients.

Computed tomography of mediastinal cystic hygroma in an adult: case report and review of the literature

Conventional and computed tomography findings in a cystic hygroma (lymphangioma) of the middle mediastinum in an adult are reported and compared with previously reported cases. The pertinent literature is reviewed.
