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) is a neuroepithelial neoplasm first described in 2003. Despite the anatomic association of PTPR with the pineal gland, the features of these tumors resemble...
5-Aminolevulinic acid (5-ALA) fluorescence-guided surgery is widely used for detection and planning of resection of malignant gliomas and other brain tumors. However, no reports have described 5-ALA f...
Intraoperative identification of cranial nerves is crucial for safe surgery of skull base tumors. Currently, there is only a small number of published papers describing the technique of t-EMG in endos...
Pineal germ cell tumors (GCTs) are primarily seen in pediatric and Asian populations. These tumors are divided into germinomatous and non-germinomatous GCTs (NGGCTs). GCTs are thought to arise by misp...
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...
This study aims to determine size of corpus callosum on midsagittal MR scan in patients with a pineal cyst and to compare it with the control group without a pineal cyst.
The purpose of this study is to compare the need to use mechanical lithotripsy between patients undergoing POC-LL and EBS for removal of difficult bile duct stones

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.
