Medical Definition of Pinealoma
1. A tumour of the pineal body composed of neoplastic nests of large cells. Tumours in this region are rare, accounting for less than 1% of intracranial tumours, although in children they constitute 3%-8% of intracranial tumours. Its symptoms include hydrocephalus, conjugate paralysis of upward gaze, disturbances of gait, and precocious puberty, the last due to suppression of pineal secretion of melatonin. Because pinealomas are near the centre of the brain, they are among the most difficult of brain tumours to remove. A variety of surgical approaches has been described. Radiotherapy and chemotherapy are also used. (12 Dec 1998)
