MRI images of the twelve-week-old, male Golden Retriever with internal hydrocephalus and acute ventricular collapse. Dorsal T2W (a), transverse T1W (b), transverse T1W after contrast administration (c) and transverse SWI (d) images of the brain. MRI showed marked thinning of the cerebral parenchyma and collapse of the hemispheres with marked subacute and chronic haemorrhage filling the adjacent subarachnoid space extending from the frontal lobe to the occipital lobe bilaterally. In the SWI sequence (d), the material presented multifocal susceptibility artifacts confirming the presence of the haemorrhages

The material between brain surface and meninges was characterized by severe heterogeneous hyperintense signal in T2W/FLAIR and heterogenous isointense T1W with moderate peripheral and internal contrast uptake (Fig. 1a-d).
Follow-up MRI three months postsurgical intervention of the Golden Retriever with ventricular collapse. Dorsal T2W (a), transverse T1W (b), transverse T1W after contrast administration (c) and transverse SWI (d) images of the brain. Repeated MRI showed an increase in volume of the cerebral parenchyma and a moderate reduction in volume of the haemorrhages in comparison to previous examination

T1W with moderate peripheral and internal contrast uptake (Fig. 2 a-d). There was moderate mass effect on the cerebellum which showed reduction in volume, irregular shape with cranial flattening. The cerebellar parenchyma showed mild increase in volume.
