Sažetak
Background: Transcranial sonography (TCS) was never used in the evaluation of pineal gland morphology. We initiated this study to evaluate the possibility of TCS to detect the region of pineal gland ; its cystic morphology and correlation with MRI scan in assumption that TCS may serve as an alternative neuroimaging method in the evaluation of pineal gland lesions. Patients: The study included 10 patients with incidental pineal gland cyst detected by MRI scan. None of the patients had history of symptoms specifically referable to the pineal gland and no surgical treatments for pineal cyst were performed. Methods: Two independent physicians performed TCS blindly on results of MRI scan, freehandedly with Aloka ProSound SSD5500. Pineal cyst was detected as every hypoechogenic area within hyperechogenic gland matrix or hypoechoic lession with or without septum was surrounded by a thin echoic wall. Maximal width in latero-lateral and antero-posterior line was measured two times and matched with MRI scans. Pearson linear correlation was performed. Results: Cysts size on TCS scan varied from 3.Sx5 mm to 17x10 mm in diameter what statistically significantly correlated with results of MRI scan (Pearsons coeflicient 0.96). Cysoc fonnations with fluid matrix resulted in decreased echogenicity on TCS, surrounded with hyperechogenic gland tissue wall. Conclusion: Our findings showed high sensitivity of TCS in the detection of the pineal region gland. Assuming appropriate temporal bone window findings of TCS also closely correlated with MRI scans and in evaluation of larger fluid consist lesions TCS revealed even better structural records.
