Intracranial monodermal teratoma presenting with growing teratoma syndrome.

Intracranial teratomas are rare. We report a case of a purely monodermal teratoma manifesting as intracranial growing teratoma syndrome. To the best of our knowledge, this is the first report of such nature in the literature.

Intramedullary conus medullaris metastasis of periurethral adenocarcinoma.

Intramedullary spinal cord metastasis to the conus medullaris is very rare. We report a 44-year-old woman with an intra-axial conus medullaris metastasis from periurethral adenocarcinoma. To our knowledge, this is the first report in the literature. We also discuss the clinical features, possible pathophysiological mechanisms and treatment options for intramedullary spinal cord metastasis to the conus medullaris.
