“…Ultrasound is a non-invasive tool that may be performed in the conscious animal, and in this case, confirmed the clinical suspicion of a connection between the brain and dorsal swelling, allowing appropriate management steps to be taken in the care of the patient. Ultrasonography has previously been used to diagnose meningocoele/meningoencephalocoele in veterinary medicine (Ohba and others 2008, Back and others 1991). Ultrasonography of the brain is, however, limited by the location and size of the acoustic window available.…”

A three-week-old rabbit was presented with a soft swelling on the dorsal aspect of the cranium and paroxysmal episodes. Ultrasonographic examination revealed that the soft tissue swelling appeared to be a fluid-filled structure directly connecting to the right lateral ventricle. Due to deterioration of the clinical signs, the rabbit was euthanased. Postmortem MRI was consistent with severe hydranencephaly and meningoencephalocoele. Despite the limitations of ultrasonographic evaluation of the brain and postmortem MRI, these imaging modalities provided invaluable data regarding the in situ structure of the lesion as an adjunct to postmortem histopathological examination.

“…In dogs, use of the bregmatic fontanelle, foramen magnum and temporal window have been described (Hudson and others 1990, Saito and others 2001). CT has also been described in the diagnosis of meningocoele/meningoencephalocoele in veterinary medicine (Ohba and others 2008, Martle and others 2009). …”

“…CT has shown considerable promise for study of lesions such as cysts, abscesses, hydrocephalus and coenurosis lesions in ruminants, including sheep, cattle and the alpaca [61][62][63][64]. Ruminant brain disorders and malformations have been observed [61,65]. These are increasingly used as the lower cost and reduced anaesthesia required in comparison to MRI is seen as favourable, especially in small ruminants and calves [66].…”

Computed Tomography - Advanced Applications

The utilisation of computed tomography (CT) in veterinary practise has been increasing rapidly in line with reduced cost, improved availability and the increase in expertise and technology. This review briefly examines the recent technological advancements in imaging in the veterinary sector, and explores how CT and micro-computed tomography (μCT) have furthered basic understanding and knowledge, and influenced clinical practise and medicine. The uses of CT technology in veterinary research, especially in relation to bone, vasculature and soft tissues are explored and compared in relation to the different species. CT is essential not only for the diagnosis and treatment of many disorders, but it is now being used to understand areas ranging from drug delivery and surgical advancements through to anatomical and educational uses throughout the world.

“…Dysraphism or a defect of the anterior fontanelle area triggers meningoencephalocele and meningocele. These defects take place in relation to agenesis of the surface ectoderm and neuroectoderm [ 2 , 4 , 5 ]. Congenital meningocele and meningoencephalocele occur in various animals, including horses, pigs, dogs, cats, and goats [ 1 , 4 - 10 ].…”

BackgroundMeningocele and meningoencephalocele of the skull are congenital deformities. Various species, such as pigs, dogs, and cats, are susceptible to congenital meningocele and meningoencephalocele and the incidence is higher in large white and landrace pigs.Case presentationIn this study, swelling was observed in the fontanel areas of the median planes of the skull cap in two female piglets of the same litter. Gross clinical examination, neurological examination, computed tomography (CT), and magnetic resonance imaging (MRI) were conducted on the symptomatic piglets. The gross clinical and neurological examinations revealed no specific findings, except for the swellings. According to the CT results, the length of the defect on the sagittal section of the skull was 4.7 mm in case 1 and 20.62 mm in case 2. Connected flow between the skull swellings and the cerebrospinal fluid (CSF) of the lateral ventricles was observed, and partial herniation was identified in case 2. On MRI, CSF with high T2 signals was identified in the arachnoid spaces between the cerebrum and the cerebellum in the two cases, which is consistent with intracranial hypertension. The size of the swelling formed in the parietal bones was 1.6 × 1.1 × 1.8 cm3 (case 1) and 1.2 × 1.38 × 1.7 cm3 (case 2). The increase in intracranial pressure was more obvious in case 2 than in case 1, and was accompanied by posterior displacements of the mesencephalon and cerebellum.ConclusionsCase 1 was diagnosed as meningocele resulting from meningeal herniation and case 2 was diagnosed as meningoencephalocele caused by brain tissue herniation.
