Right upper lobe resection is a common surgical procedure in patients diagnosed with lung cancer. However, in certain cases, there may be an anatomical variation in which the fissure between the right middle and right lower lobes is more prominently developed than usual. This atypical development can create a predisposition to torsion of the right middle lobe, a complication that may occur during or shortly after the surgical procedure, especially if pneumopexy or surgical fixation of the lung is not performed. Torsion is a rare but serious complication that can lead to significant postoperative morbidity if not promptly recognized and treated. In this case report, we provide a detailed illustration of the radiologic findings associated with right middle lobe torsion that manifested following right upper lobectomy to excise a hamartoma located in the proximal bronchus of the right upper lobe.
右上叶切除术是诊断为肺癌患者的常见外科手术。然而，在某些情况下，可能存在解剖变异，即右中叶和右下叶之间的裂沟比平常更明显地发育。这种非典型发育会使右中叶发生扭转的倾向增加，这种并发症可能在手术过程中或手术后不久发生，尤其是在未进行肺固定术或肺手术固定的情况下。扭转是一种罕见但严重的并发症，如果不能及时识别和治疗，可能导致显著的术后发病率。在本病例报告中，我们详细说明了右上叶切除术后因切除位于右上叶近端支气管的错构瘤而出现的与右中叶扭转相关的放射学表现。
