ABSTRACT
The MR imaging features of a paraganglioma of the cauda equina with associated spinal cord cysts are presented. MR imaging showed the tumor to be isointense with the spinal cord on all pulse sequences and to enhance homogeneously. The intramedullary cysts had increased signal intensity on proton density- and T2-weighted images, and involved the cervical and thoracic regions.

We present the CT, MR angiographic, and histologic findings of a rare primary meningeal melanocytoma of the cavernous sinus. The primary differential diagnosis is between a melanin-containing tumor and an extraaxial cavernous angioma. Radiologic imaging cannot distinguish between the less aggressive primary meningeal melanocytoma and the more aggressive meningeal melanoma.

Symptomatic pineal cysts are rare and typically managed with an open surgical approach. We report the successful treatment of a symptomatic pineal cyst using a stereotactic endoscopic technique.
