Pineal cysts, Symptomatic are sac-like structures formed in the pineal gland, and contain fluid. The pineal gland is located in the midline of the brain and plays a crucial role in the regulation of the sleep-wake cycle. Pineal cysts are commonly found in adults that are in their 40s. Initially, they remain asymptomatic for many years; the onset of symptoms occurs when the size of the cysts increases beyond 10 mm.
The patients commonly present headaches, vertigo, visual and oculomotor disturbances, and obstructive hydrocephalus. Less frequently, patients present with ataxia, motor and sensory impairment, mental and emotional disturbances, epilepsy, circadian rhythm disturbances, hypothalamic dysfunction of precocious puberty, and recently described the occurrence of secondary parkinsonism.
1. The pineal gland is located deep inside the brain, surrounded by different types of structures, such as vascular tissues and the third ventricle. It complicates the access to the pineal cysts for biopsy through resection. Thus, it is not completely understood.
2. Several studies are underway to elucidate cellular activities that lead to the formation of cysts. 3. However, a study suggests that hormones play a role in cyst formation in women, especially during pregnancy.

Commonly, the worsening occurs in the morning
