Abstract
Dumbbell growth is often observed in schwannoma but rarely in meningioma. In particular, the occurrence of dumbbell meningioma at the cervical cord level in Japan is markedly rare. We reported an elderly case with symptomatic meningioma that developed in a dumbbell shape from cervical spine and was treated successfully by surgery.
Highlights
Intradural extramedullary tumors account for approximately 70% - 75% of spinal cord tumors, and meningioma and schwannoma account for approximately 70% of them [1] [2]
We reported an elderly case with symptomatic meningioma that developed and grew in a dumbbell shape at the spinal cord and was treated successfully by surgery
It grows along the inner side of the dura mater and is unlikely to develop into a dumbbell type
Summary
Intradural extramedullary tumors account for approximately 70% - 75% of spinal cord tumors, and meningioma and schwannoma account for approximately 70% of them [1] [2]. In Western countries, the occurrence of meningioma and schwannoma is comparable [2], whereas the occurrence of meningioma in Japan is approximately one-fourth of that of schwannoma [3]. Dumbbell growth is often observed in schwannoma, but rarely in meningioma. The occurrence of a dumbbell meningioma at the cervical cord level is markedly rare. We reported an elderly case with symptomatic meningioma that developed and grew in a dumbbell shape at the spinal cord and was treated successfully by surgery
