Background: Seizures are a common problem in small animal neurology and it may be related to underlying diseases. Porencephaly is an extremely rare disorder, and in Veterinary Medicine it affects more often ruminants, with only few reports in dogs.
Case Presentation: A one-year-old intact male Shih-Tzu dog was referred to Veterinary University Hospital with history of abnormal gait and generalized tonic-clonic seizures. Signs included hypermetria, abnormal nystagmus and increased myotatic reflexes. At necropsy, during the brain analysis, a cleft was observed in the left parietal and occipital lobes, creating a communication between the subarachnoid space and the left lateral ventricle, consistent with porencephaly; and also a focal atrophy of the caudal paravermal and vermal portions of the cerebellum. Furthermore, the histological examination showed cortical and cerebellar neuronal dysplasia.
Conclusions: Reports of seizures due to porencephaly are rare in dogs. In this case, the dog presented a group of brain abnormalities which per se or in assemblage could result in seizure manifestation.

A patient with a history of Asian flu, mumps meningo-encephalitis, and skull-base fracture and severe porencephaly who was able to walk without assistance, has not been reported. The patient is a 65 year-old male with a history of Asian flu at 6 months of age, Mumps meningoencephalitis at 6 years of age, structural epilepsy since 15 years of age, traumatic brain injury with skull-base fracture at 51 years of age, arterial hypertension, diabetes, hyperlipidemia, previous alcoholism, and polyneuropathy. He presented with only mild right-sided spastic hemiparesis, dysarthria, decreased tendon reflexes in the lower limbs, spastic-ataxic gait, but he was able to walk unassisted.

Objectives: To clarify the prenatal magnetic resonance (MR) imaging characteristics of fetal intracranial haemorrhages (ICHs) in a large cohort and correlate them with birth outcomes.
Methods: We retrospectively reviewed MR images of fetuses with ICH on screening ultrasound (US) on picture archiving communication system (PACS) servers within a nearly ten-year period from two medical tertiary centres. The indications, main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census readings.

The alpha 1 and 2 chains of type IV collagen, encoded by the COL4A1 (MIM 120130) and COL4A2 (MIM 120090) respectively, play essential roles in the vascular basement membranes. Pathogenic variants in COL4A1/ COL4A2 are associated with autosomal dominant cerebral angiopathies. The clinical manifestations of COL4A1/COL4A2-related disorders include: aneurysms, intracerebral hemorrhage, polymicrogyria, porencephaly, heterotopia, periventricular leukomalacia, epilepsy, and neurodevelopmental disorders.

Porencephaly is an uncommon neurological condition characterized by cystic cavities or holes in the cerebral hemispheres of the brain filled with cerebrospinal fluid. There are two types of porencephaly: acquired porencephaly, also known as pseudo-porencephaly, and congenital porencephaly, also known as true porencephaly. Acquired porencephaly, also known as encephaloclastic porencephaly, typically results from late prenatal or perinatal vascular lesions caused by arterial ischemic stroke or venous thrombosis.

Article Synopsis
- - This study looked into how different MRI injury patterns in fetuses with intraparenchymal hemorrhage (IPH) relate to their causes and outcomes, using data from cases diagnosed between 1996 and 2022.
- - Researchers analyzed 44 fetuses, noting that most IPH cases were supratentorial and often linked with conditions like twin-twin transfusion syndrome and certain genetic variants (COL4A1/2).
- - The findings showed a high prevalence of neurological issues in surviving infants, with many developing cerebral palsy, developmental delays, and epilepsy, emphasizing the need for genetic evaluations in unexplained cases of fetal IPH.
