Lumbosacral perineural cysts are formed by the arachnoid membrane of the nerve root at the lumbosacral level. Most of these cysts are asymptomatic and are found incidentally during computed tomography (CT) or magnetic resonance imaging (MRI) for other causes of chronic lower back pain. This type of cyst requires a differential diagnosis to distinguish it from other causes of radiating pain and neurological symptoms. In the present case, a symptomatic lumbosacral perineural cyst was found, and pain relief was achieved by non-surgical treatment. A lumbosacral perineural cyst was identified from a differential diagnosis of a lumbar disc disorder that presented as radiating pain and neurological symptoms.
腰骶部神经周围囊肿是由腰骶神经根的蛛网膜形成的。这些囊肿大多数无症状，在因慢性下腰痛等其他原因进行计算机断层扫描（CT）或磁共振成像（MRI）检查时偶然发现。这种类型的囊肿需要进行鉴别诊断，以区别于其他引起放射性疼痛和神经症状的原因。在本病例中，发现了一个有症状的腰骶部神经周围囊肿，通过非手术治疗缓解了疼痛。腰骶部神经周围囊肿是从腰椎间盘疾病的鉴别诊断中确定的，其表现为放射性疼痛和神经症状。
