Preoperative evaluation of neural tracts by use of three-dimensional anisotropy contrast imaging in a patient with brainstem cavernous angioma: technical case report.
OBJECTIVE AND IMPORTANCE: We describe a case of brainstem cavernous angioma in which the neural tracts were evaluated before surgery by three-dimensional anisotropy contrast (3-DAC) magnetic resonance imaging. CLINICAL PRESENTATION: A 64-year-old man presented with a cavernous angioma located intrinsically in the brainstem and manifesting as gait ataxia. 3-DAC imaging demonstrated that the lesion was located outside the left inferior cerebellar peduncle and inside the middle cerebellar peduncle. INTERVENTION: The intact brain surface was incised, and the lesion was removed successfully on the basis of the preoperative 3-DAC images. The patient exhibited temporary exacerbation of his gait ataxia, but the symptom improved 3 months after surgery. Postoperative 3-DAC imaging demonstrated resection of the lesion and preservation of the left inferior and middle cerebellar peduncles. CONCLUSION: 3-DAC imaging may provide essential information about the neural tracts for the planning of brainstem surgery.
