Transcranial color‐coded real‐time sonography (TCCS) was applied to 26 patients with ventricular enlargement to quantify the ventricular size and to estimate intracranial pressure. Intracranial pressures, as determined by lumbar, epidural, or ventricular tonometry, ranged from 6.5 to 55 cm H 2 0 (8 patients had pressures > 18 cm H 2 0). The widths of the third ventricle and the frontal horns of both lateral ventricles depicted by TCCS were compared to corresponding computed tomography data: TCCS and computed tomography findings correlated well for the third ventricle ( r = 0.96) and for the right ( r = 0.86) and left ( r = 0.92) frontal horns. The capability of the septum pellucidum to undulate relative to the ventricular wall during short (20‐degree) rotatory movements of the head was related to intracranial pressure. In all patients with intracranial pressure below 17 cm H 2 0, rotatory head movements induced septum pellucidum undulation; no lateral deflection of the septum pellucidum was found in patients with an intracranial pressure above 21 cm H 2 0. Therefore, TCCS may be employed to quantify and follow‐up ventricular enlargement. Dynamic neurosonographic tests may allow a gross estimation of intracranial pressure.
