Schwannomas are one of the most common types of primary intraspinal tumors. We report a rare case of neurological aggravation due to the intratumoral hemorrhage of a cervical schwannoma. A 65-year-old man presented with lower extremity weakness developing gradually. Tumor resection was performed one week after neurological aggravation occurred. After surgery, he recovered dramatically. There are vascular and mechanical hypotheses for the etiology of intratumoral hemorrhage of schwannoma. In the present case, falling and antiplatelet drugs may have caused the intratumoral hemorrhage. Optimal surgical timing remains controversial. Some reports reveal patients recovered well after urgent surgery. However, even if urgent surgery is performed, some have neurological sequelae. Others reveal patients recovered well after elective surgery without any sequelae. Because previous reports reveal the surgical procedure may damage the spinal cord, urgent surgery may not be compulsory and elective surgery may be a better treatment option. Further investigation is needed to clarify the etiology and optimal timing for surgical treatment of intratumoral hemorrhage.
