Pineal cysts in children
Insights Into Imaging
|February 21, 2012
Summary
Pineal cysts are common in children and appear similar on MRI regardless of the reason for the scan. These benign findings are a normal variant and do not require further follow-up imaging.
Area of Science:
- Pediatric Radiology
- Neuroimaging
- Cystic Lesions
Background:
- Pineal cysts are frequently identified during pediatric neuroimaging.
- Understanding their prevalence and characteristics is crucial for accurate diagnosis.
Purpose of the Study:
- To determine the prevalence and imaging characteristics of pineal cysts in children undergoing MRI.
- To compare findings between children evaluated for idiopathic short stature (ISS) and central precocious puberty (CPP).
Main Methods:
- Retrospective monocentric study of brain MRI scans in 116 children with ISS and 56 with CPP.
- Analysis of cyst dimensions, wall/septal thickness, signal intensity, and solid components.
- Comparison of prevalence between groups using statistical tests (p < 0.05).
Main Results:
- Comparable prevalence of pineal cysts in ISS (11.2%) and CPP (10.7%) groups.
- Most cysts (74%) had thin septations and showed no changes on follow-up.
- No neurological signs were observed in children with pineal cysts.
Conclusions:
- Benign pineal cysts are a common finding in pediatric populations.
- High-resolution MRI reveals frequent septations, indicative of a normal variant.
- Routine follow-up MRI or contrast administration is generally unnecessary for these findings.

01:02The Pineal Gland
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
