Arteriovenous hemangioma in the middle mediastinum: Report of a case

Abstract

Hemangiomas in the mediastinum are uncommon, and the majority of these tumors are located in the anterior mediastinum. The present report describes an extremely rare case of a hemangioma in the middle mediastinum. A 40-year-old male patient presented with a mass in the left lower lung field on radiographic screening. Chest computed tomography and magnetic resonance imaging revealed a mass measuring 2.5 cm in diameter, which was close to the descending aorta in the left middle mediastinum. The tumor resection was performed by video-assisted thoracic surgery. The thoracoscopic findings revealed a blackish brown mass with a capsule, which had not invaded the descending aorta or cardiac sac. Histologically, the tumor was composed of typical thick-walled vessels and was therefore classified as an arteriovenous hemangioma.

Incidental discovery of a large complicated arteriovenous haemangioma

“…Haemangiomas are rare vascular tumours that account for 0.5% of mediastinal masses 1. According to the literature, approximately 125 cases of mediastinal haemangiomas have been reported from 1914 to 2000 3.…”

“…Superficial AVHs are the most common and are usually found in children, adolescents and young adults 1. The superficial form most frequently affects the head and neck, is localised to the dermis and submucosa of the lips and perioral skin, and produces a reddish blue skin discolouration.…”

“…In general, haemangiomas make up 0.5% of mediastinal masses, and of that only 1% are AVHs 1–3. Anatomically, the majority of haemangiomas in the mediastinum arise in the anterior mediastinum, with none reported in the superior mediastinum 1. This report describes a case of a large AVH with a complicated grid of vascular connections in the superior mediastinum.…”

Incidental esophageal submucosal tumor detection by chest radiography: A case report

“…Participants who are suspected of having lung cancer following a chest X-ray or sputum cytology are offered further examinations to confirm the diagnosis during a secondary evaluation. However, a number of diseases other than primary lung tumors have been diagnosed through the mass-screening program, most commonly benign lung, metastatic lung and mediastinal tumors (17–19). …”

A Rare Case of Pulmonary Arteriovenous Hemangioma Presenting as a Peribronchial Mass

“…The majority of previous reports described cases of multiple or solitary lymphangiomas or capillary and cavernous hemangiomas [ 1 - 4 ]. To date, there has been only one report describing arteriovenous malformation/hemangioma (AVMH) in the middle mediastinum [ 5 ]. Herein, we report an unusual case of pulmonary AVMH presenting as a peribronchial mass.…”
