Abstract

Epidermal cysts are common benign subcutaneous lesions that occur in or on the skin. It is not very difficult to diagnose subcutaneous epidermal cysts using ultrasound imaging because they exhibit typical sonographic features. However, the differential diagnosis can be confused when epidermal cysts are found in unusual sites. The authors report a case involving a 4-year-old girl who presented with an intramuscular epidermal cyst in the gluteus maximus muscle. Magnetic resonance imaging revealed characteristic internal features of the epidermal cyst, despite being in an uncommon site, and was very useful in the preoperative diagnosis.

표피낭종은 피부에서 기원하는 흔한 양성 피하낭종이다. 표피낭종은 초음파 검사 상에서 보통 전형적인 초음파 소견을 보이기 때문에 초음파 진단이 용이하다. 그러나, 표피낭종이 드문 부위에서 생기는 경우 감별진단이 매우 혼동 될 수 있다. 저자들은 대둔근 내에 발생한 근육내 표피낭종을 주소로 내원한 4세 여아의 증례를 보고하고자 한다. 자기공명영상에서 표피낭종이 드문 부위임에도 불구하고 표피낭종의 특징적인 소견을 보였으며 이러한 자기공명영상 소견이 수술 전 진단을 내리는데 유용하였다.
