Abstract

Endoscopic procedure for pineal region tumors and associated hydrocephalus has been getting more standard. We applied high-definition flexible neuroendoscopic system to the initial management of primary pineal malignant B-cell lymphoma. Efficacy of this new technology as an initial treatment of pineal region tumors is discussed. A 31-year-old man presented with progressive left abducens nerve palsy with headache and nausea. Magnetic resonance imaging showed multiple enhanced lesions in several cranial nerves and obstructive hydrocephalus due to a pineal cystic lesion with nodular enhancement on its roof. Diagnostic endoscopic biopsy of the pineal region tumor and ETV were performed using new flexible endoscopic system, in which a small CCD camera is implanted at the tip of the flexible scope, without complications. The thin cyst membrane was perforated and then opened with endoscopic forceps. A biopsy of the solid nodule on the cyst wall was carefully performed without injuring the surrounding venous system. We found a lot of small wartlike lesions along the third ventricular wall and fish egg-like abnormal lesions adhered to the colloid plexus around the pineal region, which were considered to be associated with dissemination....Continue Reading
