Late spinal metastases from an isolated pineal region germinoma mimicking a schwannoma.

摘要

A 20-year-old male with a prior history of germinoma presented 8 years after the initial diagnosis with progressive lower back pain. The preoperative diagnosis was schwannoma based on the appearances of a tumor in the lumbosacral region on MRI; however, histologically, a germinoma "drop" metastasis was seen. This report emphasizes the need for long-term follow-up in patients with germinoma. In addition, this patient is unusual in that the preoperative assessment favored schwannoma.
