It is displayed on Figure 1 preoperative magnetic resonance image: showing a cervicomedullary intra-axial lesion; [Figure 1a], axial section in T2 signal intensity sequence [Figure 1b], and sagittal slice in T1 intensity sequence [Figure 1c]. It is shown in Figure 1a; a transverse MRI for the resected tumor.
Intraoperative view: (a) Suboccipital craniectomy with resection of the posterior arch of C1. (b) Exposure posterior to dural opening. (c) Posterior aspect to tumor removal. 2(a): The arrow in figure 2a shows the resection of the posterior arch of C1. 2(b): The arrow in Figure 2b points to the posterior aspect of the dural opening. 2(c): The arrow in Figure 2c represents the posterior aspect after tumor removal.

T1 signal, the patient underwent a craniectomy with resection of the posterior arch of C1 that relieved the pressure, as seen in Figure 2a. The posterior exposure and removal aspects of the procedure are also shown in Figures 2b and c. The patient received subtotal resection (STR) neurosurgery at some point after the 6-month follow-up to resect the remaining tumor with use of neuronavigation, which involves the use of specialized software to create a 3D map of the brain, helping the surgeon to navigate and precisely locate the tumor during surgery [Figure 2a]. On "Figure 2a, it displayed the craniectomy with resection of the posterior arch of C1 that relieved the pressure." Another view of the posterior exposure and removal aspect is shown in "Figure 2b and c respectively." The patient has remained stable and without any further complications since the completion of treatment. A repeated MRI postoperative as displayed in "Figure 3" is taken to be monitored for any recurrence or progression of the tumor, and any necessary adjustments to the treatment plan will be made.
Postoperative magnetic resonance image in T1 intensity sequence. (a) Axial section, (b and c) sagittal section. The injury was removed in its entirety. 3(a): The arrow in figure 3a depicts the postoperative magnetic resonance image of the axial section in the T1 intensity sequence after tumor resection of the cervicomedullary lesion. 3(b): The arrow in Figure 3b shows the postoperative magnetic resonance image of the sagittal section in the T1 intensity sequence after tumor resection of the cervicomedullary lesion. 3(c): The arrow in Figure 3c represents the postoperative magnetic resonance image of the coronal section in the T1 intensity sequence after tumor resection of the cervicomedullary lesion.

Another view of the posterior exposure and removal aspect is shown in "Figure 2b and c respectively." The patient has remained stable and without any further complications since the completion of treatment. A repeated MRI postoperative as displayed in "Figure 3" is taken to be monitored for any recurrence or progression of the tumor, and any necessary adjustments to the treatment plan will be made. In addition, [Figure 3a] presents an axial section of the tumor that was surgically excised, while [Figures 3b and c] display sagittal sections of the removed tumor.
