Abstract

Leiomyosarcoma (LMS) is a soft tissue sarcoma that originates from smooth muscle cells. It is commonly found in the uterus but can occur throughout the body, including the retroperitoneal space, abdominal cavity, and any vascular structure. Although there are many case reports of uterine or vascular LMS metastasizing to the heart, cardiac metastasis from nonvisceral lesions has only been reported in two cases. Herein we report a rare case of a patient presenting metastatic LMS from the left flank in the right ventricle observed with echocardiography and enhanced computed tomography.

평활근육종은 평활근육세포에서 기원하는 연부조직 육종이다. 평활근육종은 자궁에 흔하게 발생하지만 후복막강, 복강 그리고 혈관조직에도 발생할 수 있다. 자궁 또는 혈관에서 기원하는 평활근육종이 심장에 전이된 증례는 많이 보고되었으나, 내장 외 연부조직에서 생긴 평활근육종은 매우 드물게 발생하며 심장으로의 전이는 더욱 드문 것으로 알려져 있다. 이에 좌측 측복부에서 우심실로 전이된 평활근육종의 심초음파 소견과 조영증강 컴퓨터단층촬영소견을 경험하여 보고하고자 한다.
