Out of 75 syringomyelia cases, 8 had a syringobulbic extension. The cavity was demonstrated by magnetic resonance imaging (3 cases), syringography (3 cases), ventriculography (2 cases), and myelo-CT (2 cases). The cavities could be separated into 2 groups. In the first (5 cases) the cavity extended from the floor of the fourth ventricle, anterolaterally (3 cases) or anteriorly in the midline (2 cases). The communication with the fourth ventricle was usually wide. In the second group (3 cases), the syringobulbic cavity was located anteriorly; 2 of the 3 had no communication with the fourth ventricle and had an exceptional cranial extension (syringocephalia). In selected cases, invasive studies may help to recognize the connections of the cavities, and thus be useful in planning the surgical treatment.
在75例脊髓空洞症病例中，8例伴有延髓空洞形成。空洞通过磁共振成像（3例）、脊髓造影（3例）、脑室造影（2例）和脊髓CT（2例）得以显示。空洞可分为两组。第一组（5例），空洞从第四脑室底部向前外侧（3例）或中线前方（2例）延伸。与第四脑室的连通通常较宽。第二组（3例），延髓空洞位于前方；3例中有2例与第四脑室无连通，且有特殊的颅内延伸（脊髓空洞症）。在某些病例中，侵入性研究可能有助于识别空洞的连接，从而有助于手术治疗方案的制定。
