Pineal gland cyst evaluated by transcranial sonography.

Area of Science:

• Neuroimaging
• Radiology
• Medical Ultrasound

Background:

• The pineal gland's morphology is typically assessed using Magnetic Resonance Imaging (MRI).
• The utility of Transcranial Sonography (TCS) for evaluating the pineal gland has not been previously established.

Purpose of the Study:

• To determine if TCS can differentiate normal pineal glands from those with cysts.
• To correlate TCS measurements of pineal gland cyst (PGC) size with MRI findings.
• To assess TCS for follow-up evaluation of PGC.

Main Methods:

• Sixty patients with prior brain MRI underwent Transcranial Sonography (TCS) by two blinded observers.
• Comparison of PGC detection and size measurements between TCS and MRI.
• Evaluation of interobserver agreement and correlation of measurements.

Main Results:

• All 14 pineal gland cysts (PGC) identified on MRI were detected by both TCS observers.
• No significant differences were found between TCS and MRI measurements for PGC size.
• TCS demonstrated good interobserver agreement and correlation with MRI for both PGC and normal pineal gland size.

Conclusions:

• Transcranial sonography (TCS) is a viable method for detecting and measuring pineal gland cysts (PGC).
• TCS measurements correlate well with MRI findings.
• TCS can be utilized for the detection, measurement, and follow-up of PGC.
