Abstract

Transurethral resection (TUR) is the gold standard treatment of non-muscle invasive bladder cancers. Recurrence occurs in approximately half of the patients with bladder cancer after initial TUR. Most recurrent bladder cancers present as polypoid masses with intraluminal growth originating from the mucosa. To the best of our knowledge, there has been no report on imaging findings of recurrent bladder cancers located within the subepithelial and intramural layers. Recurrent cancers within the intramural layer are difficult to detect with cystoscopy; they are also difficult to remove surgically. Imaging studies reveal the most important indicators for diagnosing subepithelial recurrent cancers. Here, we present a rare case of a recurrent bladder cancer within the subepithelial layer detected on imaging.

방광암의 경요도절제술은 비근침윤성 방광암의 1차 치료 방법이다. 첫 번째 경요도절제술 이후 약 절반가량의 방광암 환자에서 재발을 보인다. 대부분의 방광암 재발은 방광점막에서 방광내막 쪽으로 자라는 용종 모양의 종괴로 나타난다. 지금까지 알려진 바에 의하면, 재발한 방광암이 상피하종양의 형태로 보고된 증례는 없다. 근육내층에 국한된 재발암은 방광경에서 발견하기가 쉽지 않고, 또한 수술적으로 완전히 제거하는 것 역시 쉽지 않다. 근육내층에 재발한 방광암을 진단하는 데에 있어서 영상 검사가 가장 중요한 정보를 제공할 수 있다. 이 증례에서는 영상 검사에서 진단할 수 있는 아주 드문 상피하 재발 방광암에 대해 보고하고자 한다.
