Abdominal pseudohernia is a condition characterized by the protrusion of abdominal viscera through a weakened area of the abdominal wall without a hernia sac. Various causes, including spinal disorders and trauma, can lead to this condition; however, the most common cause is reported to be herpes zoster. We present a rare case of spontaneous resolution of abdominal pseudohernia following lung cancer surgery. A 71-year-old male presented with left upper abdominal bulging and pain. A CT scan performed at the time incidentally revealed a nodular lesion in the right lower lobe, suspicious for lung cancer. Single-port thoracoscopic surgery was performed, and the final diagnosis was right lower lobe lung squamous cell carcinoma. Following the lung cancer surgery, the left upper abdominal bulging spontaneously resolved within one week. In this case, we hypothesize that the immune dysregulation caused by lung cancer increased the activity of the herpes zoster virus, leading to the development of pseudohernia. The spontaneous resolution of the pseudohernia is thought to be due to the improvement of immune dysregulation after surgery.
腹部假性疝是一种以腹腔内脏器通过腹壁薄弱区域突出而无疝囊为特征的病症。包括脊柱疾病和创伤在内的多种病因可导致这种情况；然而，据报道最常见的病因是带状疱疹。我们报告一例肺癌手术后腹部假性疝自发消退的罕见病例。一名71岁男性出现左上腹隆起和疼痛。当时进行的CT扫描偶然发现右下叶有一个结节性病变，怀疑为肺癌。实施了单孔胸腔镜手术，最终诊断为右下叶肺鳞状细胞癌。肺癌手术后，左上腹隆起在一周内自发消退。在本病例中，我们推测肺癌引起的免疫失调增加了带状疱疹病毒的活性，导致假性疝的发生。假性疝的自发消退被认为是由于手术后免疫失调得到改善。
