Present a clinical case of surgical treatment of an extra-intracanal schwannoma of the C4 root through an anterior transforaminal approach with isolation and mobilization of the V2 segment of the vertebral artery and summarize the scientific literature data on diagnostic and treatment methods.
Clinical case. Patient V., 19 years old, presented with complaints of weakness in the proximal parts of the right upper limb. MRI visualized an extra-intracanal mass at the C3-C4 vertebrae level, measuring 25×26 mm on the right side. The mass was removed via an anterior transforaminal approach, with isolation of the V2 segment of the right vertebral artery. The histological conclusion corresponds to a schwannoma G1.
Conclusion. Patients with extra-intracanal schwannomas require thorough preoperative examination, with the selection of an appropriate type of surgical intervention that minimizes the risk of complications, such as damage to the V2 segment of the right vertebral artery and nerve structures.
