title: [T1-T2 disc herniation: two cases].
abstract: We report two cases of exceptional first thoracic disc herniation in a 60-year-old man and a 55-year-old woman. The man was treated surgically and the woman medically. Osteoarthritis appeared to be the predominant cause of the disc herniation in both patients. Unlike the usual calcification in the medioposterior position for middle or lower thoracic spine herniations, a soft posterolateral herniation was observed here. The symptoms are limited, as observed in both patients, to a T1 radiculopathy, to be distinguished from C8 radicopathy. Myelopathy is rare. Claude-Bernard-Horner syndrome is not constant but highly suggestive. Both of these signs were absent in our patients. T1-T2 disc herniation should be suspected in patients presenting cervico-brachial medial neuralgia. MRI provides the diagnosis. Anterior surgery can be achieved without sternotomy. Careful radiographic analysis is needed preoperatively to identify the upper limit of the sternum.
