Lumbar pedicular agenesis is a rare clinical and radiological finding. Therefore, it is commonly misdiagnosed, particularly in trauma cases, with the first case being reported by Hadley in 1946. Pedicle agenesis has specific radiographic features: a falsely appearing enlarged neural foramen; a dysplastic, dorsally displaced ipsilateral articular pillar and lamina; and a dysplastic ipsilateral transverse process. Computed tomography (CT) is the preferred diagnostic modality for pedicle agenesis and it is important to note that pedicle agenesis is a stable congenital anomaly. Typically, these patients do not exhibit neurological deficits and are managed conservatively or receive no treatment. In this case report, we will be reporting a case involving the absence of L5 left pedicle.
腰椎椎弓根发育不全是一种罕见的临床和影像学表现。因此，它常被误诊，尤其是在创伤病例中，首例病例由哈德利在1946年报道。椎弓根发育不全具有特定的影像学特征：神经孔假性增大；同侧关节突和椎板发育不良且背侧移位；以及同侧横突发育不良。计算机断层扫描（CT）是诊断椎弓根发育不全的首选检查方式，需要注意的是，椎弓根发育不全是一种稳定的先天性异常。通常，这些患者不会出现神经功能缺损，采取保守治疗或无需治疗。在本病例报告中，我们将报告一例涉及L5左侧椎弓根缺如的病例。
