Posterior rectus sheath hernia is a truly rare finding, with only 11 documented cases since the first report in 1937. A posterior rectus sheath hernia is herniation of bowel and/or omentum through the posterior portion of the rectus sheath, but not through any other structure. This can only occur medial to the spigelian fascia, differentiating it from a spigelian hernia. Previous missed cases have led to complications such as bowel incarceration, obstruction or even strangulation and have required surgical intervention. In this case report, we describe an incidental finding of a non-complicated posterior rectus sheath hernia in an 83-year-old male. Annotated cross-sectional imaging provides anatomical context that is not widely available in the existing literature. Due to its rarity and potential complications, it is also important to report this case in order to enhance the evidence base for posterior rectus sheath hernia and to familiarize this uncommon condition to radiologists, clinicians and surgeons.
腹直肌后鞘疝是一种极为罕见的病症，自1937年首次报告以来，仅有11例文献记载。腹直肌后鞘疝是指肠管和/或网膜通过腹直肌后鞘的后部突出，但不通过任何其他结构。这种情况仅发生在半月线筋膜内侧，从而与半月线疝相区别。既往漏诊的病例已导致诸如肠管嵌顿、梗阻甚至绞窄等并发症，且需要手术干预。在本病例报告中，我们描述了一名83岁男性偶然发现的非复杂性腹直肌后鞘疝。带注释的横断面成像提供了现有文献中未广泛提供的解剖学背景。鉴于其罕见性和潜在并发症，报告此病例对于加强腹直肌后鞘疝的证据基础以及让放射科医生、临床医生和外科医生熟悉这种罕见病症也很重要。
