This study illustrates intraosseous pneumatocyst of the vertebral body, a benign lesion.
To review the incidence and location of this benign lesion during a 1-year period.
Intraosseous pneumatocyst is a rare benign condition, commonly seen in iliac bone or sacrum. The etiology of this entity is unclear. Other locations of these lesions are very rare, and only a few isolated cases are reported in the literature.
In the last year (1994-1995), vertebral pneumatocyst was incidentally found in four patients who underwent computed tomography examination for presumptive discal lesion. Axial computed tomography with 2- and 4-mm slice thickness was performed.
The typical computed tomography patterns of intraosseous pneumatocyst involving the cervical, dorsal, or lumbar spine were found. The bony structure and joints were normal. To the best of our knowledge, intraosseous pneumatocyst located in the spinal process has not been reported.
Intraosseous pneumatocyst is a benign lesion. Biopsy and follow-up are unnecessary.
本研究阐述了椎体骨内气囊样囊肿，一种良性病变。
回顾这一良性病变在1年期间的发病率及部位。
骨内气囊样囊肿是一种罕见的良性病症，常见于髂骨或骶骨。该病症的病因尚不清楚。这些病变的其他部位非常罕见，文献中仅报道了少数孤立病例。
在过去一年（1994 - 1995年），4例因疑似椎间盘病变接受计算机断层扫描检查的患者偶然发现了椎体气囊样囊肿。进行了层厚为2毫米和4毫米的轴向计算机断层扫描。
发现了累及颈椎、胸椎或腰椎的骨内气囊样囊肿的典型计算机断层扫描表现。骨质结构和关节正常。据我们所知，位于棘突的骨内气囊样囊肿尚未见报道。
骨内气囊样囊肿是一种良性病变。无需活检及随访。
