What Is the Treatment for Pineal Cyst?

The pineal body (conarium) [kEJ`neErIEm] is located between the anterior thalamus and thalamus of the midbrain. A reddish brown bean-shaped body. It is a gray-red oval body with a length of 5 to 8 mm and a width of 3 to 5 mm. It weighs 120 to 200 mg and is located at the top of the third ventricle. Therefore, it is also called honey epiphysis. The ventricle is connected to the top of the ventricle, and the third ventricle protrudes into the stalk to form a pineal crypt.

The pineal body is a gray-red oval body with a length of 5 to 8 mm and a width of 3 to 5 mm. It weighs 120 to 200 mg and is located at the top of the third ventricle, so it is also called epiphysis. It is connected to the top of the third ventricle by a thin handle, and the third ventricle protrudes into the handle to form a pineal crypt. The surface of the pineal gland is covered with connective tissue membranes that extend from the pia mater. The capsules extend into the parenchyma with the blood vessels and divide the parenchyma into many irregular leaflets. Nerve fibers and other components. Pineal somatic cells are the main cells in the pineal gland. In HE stained specimens, the cells were round or irregular. Nuclei are large, round, irregular or lobed, lightly colored, and the nucleoli are distinct. The cytoplasm is weakly basophilic and contains a small amount of lipid droplets. In the silver-plated specimens, the pineal somatic cells were irregular in shape and had protrusions of varying lengths. The ends of the protrusions swelled and often stopped around the blood vessels. Under the electron microscope, there are rough endoplasmic reticulum, Golgi complex, and small circular secretory particles in the cytoplasm. Melatonin is contained in the particles. There are also abundant mitochondria, free ribosomes and lipid droplets in the cytoplasm. The cell membrane often forms synapses with nerve endings; synaptic ribbons can be seen near the synapses of pineal cells. Synaptic ribbons are composed of small rod-like structures with high density of electrons and surrounding vesicles. Unclear. There are fewer glial cells, located between the pineal gland cells. In HE stained specimens, the cell body was small, the shape was irregular, the nuclei were small, and the staining was deep. The cells have protrusions, and the ends attach to the pineal cells or extend into the space around the blood vessels. The electron microscope showed that the cytoplasm was rich in rough endoplasmic reticulum, free ribosomes and microfilaments. Some round, oval, or irregular calcified particles can also be seen between the pineal somatic cells, called brain sand. Its ingredients are mainly calcium phosphate and calcium carbonate. Brain sand generally appears after puberty, and its amount increases with age. The functional significance of brain sand is unclear, some people think. The amount of brain sand may reflect its past hormone secretion activity. The nerves of the pineal gland mainly come from the presympathetic ganglion fibers, and the nerve endings mainly stop in the perivascular space, and a small amount stops between the pineal cells, and some form synapses with the cells.

(I) Histological classification

1. Germ cell-derived tumor:

1. Increased intracranial pressure: headache, vomiting, vision loss, abductor nerve paralysis, etc.

2. Impaired vision and hearing impairment

3. Unsteady gait, slow coordination

4. Diabetes insipidus

5. Germ cell tumors may appear as precocious puberty; pineal somatomas are characterized by stagnant sexual development or non-development

Comprehensive treatment should be carried out for tumors in this area: general radiotherapy, gamma knife treatment, drug treatment and surgical treatment; biopsy methods with clear pathology include stereotactic biopsy and neuroendoscopy.
