| ==Overview==
| |
| Pinealoma is a tumor of the [[pineal gland]].
| |
| | |
| ==Pathophysiology==
| |
| * The pineal gland produces the hormone [[melatonin]] which plays a role in regulating [[circadian rhythms]]. A pinealoma may disrupt production of this hormone, and [[insomnia]] may result.
| |
| * Frequently, paralysis of upward gaze along with several ocular findings known collectively as [[Parinaud's syndrome]] are the only physical symptom seen. This is caused by the compression of the [[vertical gaze center]] in the [[midbrain tectum]].
| |
| | |
| ==Symptoms==
| |
| * [[Insomnia]]
| |
| * [[Palpitaions]]
| |
| * Other symptoms may include [[hydrocephalus]], [[gait disturbance]]s, and [[precocious puberty]].
