Fig. 2.4

Brain MRI in a patient with communicating hydrocephalus (a, b) and in a patient with a non-communicating hydrocephalus secondary to aqueductal stenosis (c, d). Midsagittal 3DT2WSS sequence (CISS) (a, c) and 3DT2WTSE sequence (SPACE) (b, d) images. Observe the presence of a normal morphology of the aqueduct and normal cerebrospinal fluid flow through the aqueduct in the patient with a communicating hydrocephalus (arrows), and the thickened mesencephalic tectum (probable tectum glioma) and absence of the CSF flow in the patient with aqueductal stenosis (arrows). Note the presence of normal CSF flow through the Magendie foramen (short arrow). Reproduced from Rovira A. Communicating Hydrocephalus. Normal Pressure Hydrocephalus. In F. Barkhof et al.
