Endoscopic resection of pineal tumors using an endoscope with a mounted rigid suction that allows bimanual handling of the tumor for resection. This contrasts to the established method of biopsy of pineal tumors through intraventricular approach.
Two patients, one with a cystic lesion in the pineal region and one with a large pineal tumor, were operated in sitting position through a subtorcular approach. Endoscope was held in the left hand with suction tip extending beyond the tip through its instrument channel. Regular microsurgical instrumentation/CUSA/Nico Aspirator was used with the right hand for dissection, cutting, and removing the tumor under endoscopic vision.
Surgeon comfort was superior to when microscope is used in sitting position. Complete resection was achieved in all cases.
The two-handed endoscopic technique using a mounted suction on the endoscope as described is a safe and effective strategy for resecting pineal region tumors.

Papillary tumor of the pineal region (PTPR) represents a recently described entity and was included in the 2007 World Health Organization (WHO) classification of central nervous system tumors. The bio...
Pineal metastasis is uncommon and most metastatic pineal lesions are asymptomatic. To our knowledge the herein reported case is the first in which the pineal gland was confirmed as the metastatic site...
Pineal tumors are rare, about 1% of all intracranial tumors. At variance with pineocytomas, usually characterized by a good prognosis, papillary tumors behave more aggressively. Owing to their rarity,...
Pineal anlage tumor (PAT) is a rare subtype of pineoblastoma (PB), which shows a poor prognosis. We report a case of a 5-year-old boy with PB with a rhabdomyoblastic component. He presented at a local...

Neoplasms which originate from pineal parenchymal cells that tend to enlarge the gland and be locally invasive. The two major forms are pineocytoma and the more malignant pineoblastoma. Pineocytomas have moderate cellularity and tend to form rosette patterns. Pineoblastomas are highly cellular tumors containing small, poorly differentiated cells. These tumors occasionally seed the neuroaxis or cause obstructive HYDROCEPHALUS or Parinaud's syndrome. GERMINOMA; CARCINOMA, EMBRYONAL; GLIOMA; and other neoplasms may arise in the pineal region with germinoma being the most common pineal region tumor.

A light-sensitive neuroendocrine organ attached to the roof of the THIRD VENTRICLE of the brain. The pineal gland secretes MELATONIN, other biogenic amines, and neuropeptides.
Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.
Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
