Cervical myelography was performed in fourteen patients under suspicion of cervical disc herniation. Prior to myelography, complete cranial-CT registration of the density in the subarachnoid space, intraventricularly, subcorticaly and periventriculary was performed. Control scans 3, 6, 24 and 48 hours following myelography disclosed intracranial contrast media at level of basal cistern, the fourth ventricle and Sylvian fissure. Nine and eleven patients, respectively, had enhancement in the third and lateral ventricles. All patients had subcortical enhancement and nine patients had periventricular enhancement. At the first three hours after cervical myelography minor subcortical and periventricular edema was disclosed, which resolved during the subsequent hours. Two days after myelography, minimal residual contrast was disclosed subcortically at the level at the Sylvian fissure and in the subarachnoid space at the level of the Sylvian fissure and the convexity. It is recommended, that diagnostic cranial-CT is performed before cervical myelography or at a minimum of three days after cervical myelography.
对14例疑似颈椎间盘突出症的患者进行了颈椎脊髓造影。在脊髓造影前，对蛛网膜下腔、脑室内、皮质下和脑室周围的密度进行了完整的头颅CT记录。脊髓造影后3、6、24和48小时的对照扫描显示基底池、第四脑室和大脑外侧裂水平有颅内造影剂。分别有9例和11例患者第三脑室和侧脑室有强化。所有患者均有皮质下强化，9例患者有脑室周围强化。颈椎脊髓造影后最初3小时发现轻微的皮质下和脑室周围水肿，随后数小时内消退。脊髓造影后两天，在大脑外侧裂水平的皮质下以及大脑外侧裂和脑凸面水平的蛛网膜下腔发现少量残留造影剂。建议在颈椎脊髓造影前或至少在颈椎脊髓造影后三天进行诊断性头颅CT检查。
