Posterior Cervical Intradural Neuromuscular Choristoma: Case Report and Review of the Literature

Neuromuscular choristomas are peripheral nerve tumors typically composed of mature nerve fibers and striated muscle fibers. Choristomas associated with nervous tissue as a broader category are rare, with 49 cases reported in the literature. Only 2 neuromuscular choristomas were associated with the spine, both in the lumbosacral spine and intimately associated with a lipoma. This case is, to our knowledge, the first reported case of intradural cervical neuromuscular choristoma in the published literature.
