Recently, intracapsular enucleation has been reported as the standard treatment of neurogenic tumors arising from the cervical sympathetic region. In the present study, we performed intracapsular enucleation for two neurogenic tumors derived from the sympathetic chain. Case 1; A 61-year-old female who presented with an asymptomatic cervical mass. Based on the imaging findings, we suspected a neurogenic tumor and performed intracapsular enucleation. Histopathologic examination revealed a schwannoma. After surgery, transient Horner’s syndrome was observed. Case 2; A 32-year-old female consulted for a 10-year history of the left cervical mass. There was no neural deficit. From the imaging findings, and the presence of café au lait spots on the body trunk, the lesion was suspected as being a neurogenic tumor. Intracapsular enucleation was performed, and a histopathologic examination revealed a neurofibroma. Postoperative palsy did not occur. In spite of the same surgeon employing the same method in both the above cases, postoperative palsy occurred in the former, but did not in the latter. Postoperative nerve palsy can sometimes occur, even if intracapsular enucleation was performed. Therefore, adequate preoperative informed consent is required.
