ABSTRACT
Teratoma of mediastinum is rare germ cell tumor. Anterior mediastinum is the most common extragonadal site. Benign mediastinal teratoma accounts for 60% of all mediastinal germ cell tumors. Benign mature teratoma has excellent prognosis after surgical excision. We present a case of 20-year-old woman diagnosed as benign mature teratoma which compressed main pulmonary trunk. The patient underwent surgical excision.

Figure 1: Chest X-ray showing protruding well-defined mass shadow in the left upper hilar space.

Mentions: A 20-year-old woman who presented with increasing dyspnea on exertion was referred to our hospital for evaluation of a mediastinal mass. There were no complaints of fever or weight loss. On physical examination, electrocardiogram was normal. Chest X-ray revealed bulging mass opacity in the left upper hilar space (Fig. 1). Transthoracic echocardiography showed well-defined lobulated round mass compressing main pulmonary trunk in the parasternal short axis view (Fig. 2, Supplementary Videos 1, 2, www.jocmr.org). Chest CT demonstrated a well-demarcated lobulated mass of a 7 × 4 × 4 cm size with heterogeneous enhancement and fat component in the anterior mediastinum. The mass compressed main pulmonary trunk, and there was no definite invasion to lung (Fig. 3). The patient underwent surgical excision. Histopathologic examination confirmed the diagnosis of a benign mature teratoma (Fig. 4). The excised mass consisted of multiple areas of mature epidermis with sebaceous glands, nests of respiratory epithelium and pancreatic tissue, and foci of mature adipose tissue. The patient was uneventful and discharged without complication.
