Sažetak
Background: Transcranial sonography of brain parenchyma was never used in evaluation of morphology of pineal gland. 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 evaluation of pineal gland lesions. Patients: Ten patients with incidental pineal gland cyst detected by MRI scan and without any previous documented data of disease related to pineal gland were evaluated by TCS. Methods: Two independent physicians performed TCS blindly on results of MRI scan, freehandedly with Aloka ProSound SSD-5500. Pineal cyst was detected as every hypoechogenic area within hyperechogenic gland matrix or hypoechoic lession with or without septum 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: Examination was possible in 10 out of 13 patients, three patients were excluded due to insufficient temporal "bone window". Cysts size on TCS scan varied from 3, 5x5 mm to 17x10 mm in diameter what statistically significant correlated with results of MRI scan (Pearson's coefficient 0, 96). Also, interobserver reliability of this method was significant (r=0, 99 p<0, 05). Conclusion: Our findings showed high sensitivity of TCS in detection of region of pineal gland. Assuming appropriate temporal bone windows findings of TCS also closely correlated with MRI scans suggesting that TCS is competitive method of neuroimaging to MRI in evaluation of pineal gland lesions.
