What is craniopharyngioma

summary

There are many kinds of tumors, but many people don't know about craniopharyngioma, and even feel very strange. Let's learn about craniopharyngioma.

What is craniopharyngioma

First, cranioeustachian tube tumor is a congenital disease with slow growth. During normal embryonic development, the craniopharyngeal canal, which connects Rathke's sac with the primitive oral cavity, gradually disappears with embryonic development. The residual part of the anterior wall of Rathke's capsule, the nodular part of the anterior lobe, and the residual squamous epithelial cells of the degenerated craniopharyngioma may be the origin of craniopharyngioma. Therefore, craniopharyngiomas may occur in the pharynx, sphenoid sinus, intrasellar, suprasellar and third ventricle, and some may invade the posterior cranial fossa.

Second, craniopharyngiomas are congenital tumors, accounting for about 5% of intracranial tumors. More common in children and adolescents, male than female. Most of the tumors are located in suprasellar region, which can develop to the third ventricle, hypothalamus, interphalangeal cistern, parasellar, bilateral temporal lobe, frontal lobe floor and intrasellar area. They compress optic nerve and optic chiasm, block cerebrospinal fluid circulation and lead to hydrocephalus.

Third, the main symptoms and signs of craniopharyngioma are visual impairment, visual field defect, diabetes insipidus, obesity, delayed development and so on. Adult males have sexual dysfunction and females have irregular menstruation. Intracranial pressure may increase in late stage.

matters needing attention

Craniopharyngioma patients in addition to actively cooperate with the treatment, but also pay attention to maintain a good mood, can not appear too emotional situation, so the treatment of the disease has a great impact.
