pinealoma

Pinealoma is often grouped with brain tumors because of its location.

A pinealoma may disrupt production of this hormone, and insomnia may result.

Pinealoma is a tumor of the pineal gland.

Young patients with brain tumors in the pineal gland or midbrain: pinealoma (intracranial germinomas) are the most common lesion producing this syndrome.

There was an increased, but non-significant, incidence of other cancers, based on two cases (one pinealoma and one Hodgkin's disease) occurring among those aged 15-24 years during 1984-90.

A pinealoma may cause interruption of hypothalamic inhibiting pathways, sometimes leading to beta-hCG secretion and consequent Leydig's cell stimulation.

Whether to characterize these germ cell neoplasms as pinealomas is still a subject of debate, but most pinealophiles favor restricting the terms pinealoma to neoplasms arising from the pineocytes.

He is well known for the medical term Parinaud's syndrome, which is, "A dorsal midbrain lesion such as pinealoma which results in vertical gaze palsy, convergence-retraction nystagmus and light-near dissociation".
