case_images: Dorsal T1-weighted (A) and transverse 3D-Gradient Echo in Steady State at the level of the thalamus (B) MR-images of the brain of a cat revealed two CSF-filled cavities consistent with bilateral porencephaly. A focal lesion located in the right parietal lobe (long arrow) showed communication with neither the ipsilateral lateral ventricle nor the sub-arachnoid space. A second, extensive lesion extending from the left lateral ventricle to the cortical surface at the level of the parietal and temporal lobes (short arrow) is seen.

case_images: Two PCs were found in 7 (21.9%) cases (Figure 1), of which both lesions showed a communication with both the ventricular system and the subarachnoid space in four of seven cases.
case_images: Dorsal T1-weighted MR-images of the brain of a dog showing a porencephalic cavity in the right temporal lobe at level of the caudal collicoli (A) and a slice below (B). A temporal bone fracture (long arrow) associated with a mild depression of the overlying calvarium is appreciated. Abnormal signal of the right temporal muscle (fat infiltration) is also present (short arrow).

case_images: All fourteen cases with fractures presented at least two further musculoskeletal changes and then were classified as presumed acquired traumatic forms (Figure 2).
case_images: Dorsal (A) and transverse at the level of the inner ears (B) T1-weighted MR-images of the brain of a dog with an extensive unilateral cavity extending from the left lateral ventricle to the cortical surface. A severe mass effect leading to a right midline shift is present. The cranial vault over the porencephalic cyst is stretched and thinned (arrow).

case_images: Thinning of the calvarium overlying the PC was seen in 3 cases (Figure 3).
case_images: Parasagittal T2-weighted (A) and transverse T1-weighted (B) MR-images of the brain of a dog showing a porencephalic cavity in the left parietal lobe and associated meningoencephalocele (arrow).

case_images: Meningocele (MC) or meningoencephalocele (MEC) was seen in four cases, all located at the level of the parietal lobe (Figure 4).
