However, their occurrence on the vagus is uncommon. A high index of suspicion is needed to order imaging in pelvic lesions that present atypically. Discussion: Schwannomas are hypointense on T1 and heterogeneously hyperintense on T2 on MRI. The histopathological appearance with Antoni type A and type B is typical of Schwannoma. Conclusion: Schwannomas are slow growing benign tumors that are separable from the parent nerve. Recurrence is uncommon after resection.展开更多
文摘Introduction: Neurogenic tumors include schwannomas and neurofibro-mas. They occur often in the head and neck. However, their occurrence on the vagus is uncommon. A high index of suspicion is needed to order imaging in pelvic lesions that present atypically. Discussion: Schwannomas are hypointense on T1 and heterogeneously hyperintense on T2 on MRI. The histopathological appearance with Antoni type A and type B is typical of Schwannoma. Conclusion: Schwannomas are slow growing benign tumors that are separable from the parent nerve.
