Objective.To evaluate the forward shifting of cervical spinal cords in different segments of patients with Hirayama disease to determine whether the disease is self-limiting.Methods.This study was performed on 11 healthy subjects and 64 patients. According to the duration, the patients were divided into 5 groups (≤1 year, 1-2 years, 2-3 years, 3-4 years, and ≥4 years). Cervical magnetic resonance imaging (MRI) of flexion and conventional position was performed. The distances between the posterior edge of the spinal cord and the cervical spinal canal (X), the anterior and posterior wall of the cervical spinal canal (Y), and the anterior-posterior (A) and the transverse diameter (B) of spinal cord cross sections were measured at different cervical spinal segments (C4 to T1).Results.In cervical flexion position, a significant increase inX/Yof C4-5 segments was found in groups 2–5, the C5-6 and C6-7 segments in groups 1–5, and the C7-T1 segments in group 5 (P<0.05). The degree of the increasedX/Yand cervical flexionX/Yof C5-6 segments were different among the 5 groups (P<0.05), which was likely due to rapid increases inX/Yduring the course of Hirayama’s disease.Conclusion.TheX/Ychange progression indicates that Hirayama disease may not be self-limiting.

Abstract OBJECTIVE Although an anterolateral approach is an ideal approach to the anterior part of the cervical spinal canal, it is not often used because of various technical difficulties. This article presents the case of a patient with an intradural schwannoma ventrolateral to the spinal cord and describes the technique, anterolateral surgery without fixation, that was used to remove it. CASE PRESENTATION A 71-year-old man presented with neck pain and easy fatigability of the legs. Magnetic resonance imaging showed an intradural tumor ventrolateral to the spinal cord at the C3 level. The diagnosis was a schwannoma. TECHNIQUE A right anterolateral approach was selected for the resection. In the dissection between the sternocleidomastoid muscle and the internal jugular vein, the accessory nerve was retracted with the fat tissue. At C3, the prevertebral aponeurosis was laterally retracted to protect the sympathetic chain. The C3 transverse process was rongeured, and the vertebral artery was shifted laterally with the venous plexus. The C2–C3 uncovertebral joint and the right third of the C3 body were removed (partial corpectomy). The tumor was easily found in the dural sac and was totally removed. The surgical wound was closed in a watertight fashion. No fixation was necessary. The symptoms improved after the operation. DISCUSSION The anterolateral approach is one of the best approaches for resecting ventrally located intradural lesions because it allows minimally invasive surgery. Control and protection of the accessory nerve, sympathetic chain, and vertebral artery are the keys to success.

ABSTRACTA 17-year-old male, who gave up his favorite sport cricket and started playing football, presented with one-year history of slowly progressive atrophic weakness of forearms and hands. Neurological examination showed weak and wasted arms, forearms and hand but no evidence of pyramidal tract, spinothalmic tract and posterior column lesions. Plain cervical spine radiographs showed no abnormal fi ndings. Cervical magnetic resonance imaging (MRI) showed asymmetric cord atrophy; images obtained with neck fl exed showed the anterior shifting of the posterior wall of the lower cervical dural sac resulting in cord compression. These fi ndings suggest Hirayama disease, a kind of cervical myelopathy related to the fl exion movements of the neck.
