Lumbar Extramedullary Intradural Bronchial Cyst

A 28-year-old woman came to the hospital due to pain in the right buttocks that aggravated after coughing or fatigue and alleviated after rest. Dynamic enhanced magnetic resonance revealed an intradural, extramedullary dorsal mass at the L1–L2 level, adhered to the peripheral nerve fiber bundle. The lesion showed equal signal on T1WI and high signal on T2WI and showed no enhancement after injection of contrast agent [Figure 1a–c]. The patient has scoliosis [Figure 1d]. Pathological examination indicated a bronchogenic cyst.Figure 1: A nodular lesion is seen in the subarachnoid space at the L1–L2 level, (a) yellow arrow represents the L2 vertebral; (b) subarachnoid expansion (green arrow), and (c) spinal cord compression (blue arrow).(d) figure shows scoliosisSpinal bronchiolar cyst is a rare congenital malformation characterized by endodermal (neuroenteric, intestinal borne) cysts covering the respiratory epithelium.[1] Lesions often occur in middle-aged and young men, and their clinical manifestations are related to the location of the lesion in the spinal canal. Patients may present with neck or back pain, radiation pain in the extremities, and movement and sensory disturbances, often with other spinal and spinal cord congenital malformations. The imaging findings of spinal bronchiolar cysts have no obvious specificity and need to be confirmed by pathological examination. The aim of surgery is total resection, but due to the high recurrence rate, partial resection, cystic fenestration, and biopsy should be avoided.[2] Intraspinal tumors should consider the possibility of bronchial cysts.
