초록

윤활막육종은 주로 사지, 특히 무릎 근처에 발생하는 악성 연부조직 종양으로, 가슴벽에 발생한 경우는 매우 드물다. 저자들은 26세 여성에서 앞가슴벽에 발생한 윤활막육종의 증례를 CT 및 MRI 소견을 중심으로 보고하고자 한다. CT에서 흉막하에 위치한, 경계가 좋으며 석회화를 동반한 작은 종괴로 관찰되어, 처음에는 양성 종양으로 생각하였다. 하지만 갑자기 심한 통증과 함께 종괴의 출혈과 혈흉이 동반되어 악성의 가능성을 고려하였다. MRI에서는 다엽성 종괴 내부에 액체액체층이 보였고, 이는 윤활막육종의 특징적인 영상 소견이다.

Synovial sarcoma is a malignant soft tissue tumor that usually involves the extremities, particularly near the knees; a synovial sarcoma originating in the chest wall is extremely rare. We describe a 26-year-old woman diagnosed with a synovial sarcoma originating in the chest wall, based on CT and MRI findings. Contrast-enhanced CT images revealed a small, well-defined enhancing mass with calcification, in the subpleural area. This lesion was initially diagnosed as a benign tumor; however, the patient developed sudden severe pain with spontaneous bleeding and hemothorax, suggesting the possibility of malignancy. MRI revealed a multilobulated mass with a fluid-fluid level, which characterizes a synovial sarcoma.
