A ultrassonografia tem sido utilizada para avaliar espina, canal medular desde . Current selection criteria and perioperative therapy used for fetal myelomeningocele surgery. We believe that ultrasonography should be performed on patients who are at high risk of occult spinal dysraphism, such as those presenting cutaneous stigmas, congenital abnormalities, or neurological alterations, as ameans of early diagnosis, thereby avoiding neuropsychomotor sequelae later on.

A fine radiopaque line of contrast medium is observed between the two hemicords black arrow. Atendimento ao Aluno 11 Transfontanellar ultrasonography did not show any abnormalities.
The cause of these clinical signs is believed to be a microscopic alteration in the ventral commissural interneurons in the lumbosacral intumescence that are involved with gait De Lahunta and Glass The neurologic localization was supported by the Myelo-CT findings.
R e pela S. Braz J Vet Pathol 1, However, detecting this condition in neonates is difficult since the neurological signs in these patients are not apparent. A possible mode of inheritance for spinal dysraphism in the dog with a more complete description of the clinical syndrome.
In three prospective studies in the literature, the highest incidence reported, in an evaluated population of 2, patients, was 7. Y estas afecciones pueden tratarse.
Previous human studies have also demonstrated that the severity of spinal dysraphism lesion may be underestimated with radiography and ultrasonography, and have recommended that patients should also be evaluated using MRI or Myelo-CT to delineate spinal cord lesions, the position of neural structures and associated anomalies Orakdogen et al High-resolution ultrasonography is a fast and accurate method for screening for occult dysraphic lesions.
High-resolution ultrasonography using a linear transducer made it possible to identify and characterize the lesion, and magnetic resonance imaging confirmed the type of lesion lipomyelomeningocele and enabled adequate surgical planning. Magnetic resonance imaging should be reserved for patients with positive or inconclusive results from ultrasonography, for confirmation of the diagnosis and surgical planning, as reported in the present case, in which the ultrasonographic findings were fully confirmed by the magnetic resonance imaging.
Examination at this area in transverse and sagittal planes showed a round hyperechoic dura mater, and a hypoechoic space corresponding to the subarachnoid space. Cases of multiple stigmas comprise another group at risk . Of these, only 5. Split cord malformation type II or diplomyelia consists of two hemicords housed within a single dural sac separated by a fibrous septum Pang et al These spinal cord lesions most likely occurred during primary neurulation and are uncommon in domestic animals.
It may be suspected in asymptomatic newborns because it is generally associated with abnormalities of the adjacent skin, such as cutaneous stigmas, hemangiomas, hair tufts, cutaneous appendices, sacrococcygeal dimples, and subcutaneous masses, particularly in the lumbosacral region .

The protocol to neonates with high risk of occult spinal dysraphism has demonstrated good results; however, the physicians should be aware of neonates with cutaneous stigma because of high incidence of occult spinal dysraphism.
The ultrasonographic findings from the spine espinao 1 discontinuity of ocultq posterior bone layers in the L5 and S1 projections, with an intracanal solid formation presenting undefined margins and a heterogenous hyperrefringent interior, adhering to the distal segment of the medullary cone; 2 a medullary cone extending beyond the L3 body Figure 2.
Características de mielografía con TC de una disrafia espinal en un perro mestizo joven
Additionally, three-dimensional CT reformatting software tools can be used to more clearly visualize the surface appearance of the vertebral column defects including spina bifida, hemivertebrae and others. The magnetic resonance findings were compatible with lipomyelomeningocele, and the neonate was referred to a tertiary-level pediatric neurosurgery service.
Spinal dysraphism includes dorsal midline defects derived from disrafa secondary mal-development of ectoderm, mesoderm, and neurectoderm layers of tissue, and encompasses a variety of malformations including spina bifida, meningocele, meningomyelocele, syringomyelia, split cord anomalies diplomyelia, diastematomyeliaand others De Lahunta and Glass Occult spinal dysraphism is defined as a group of dysraphic conditions present below an intact cover of dermis and epidermis.
McLone DG, et al. Basedon thephysicalfindings, cases of spinal dysraphism can be grouped into two categories: Imaging diagnosis-ultrasonographic diagnosis of diplomyelia in a calf. Its prevalence is greater among females and in poor people .
Spina dlsrafia in a German shepherd puppy. Sweeps in longitudinal and transverse planes were performed, with the aims of making a detailed assessment of the contiguity of the anatomical features with themedullary canal: Scar at the perineal area were probably due to previous decubitus ulcers or skin irritation associated to decrease sensation at the perineal area. The incomplete ossification of the posterior elements of the more caudal vertebrae in children of up to five or six months of age provides a good acoustic window for viewing the content of the vertebral canal and the bone structures .
Magnetic resonance imaging is another diagnostic imaging method for evaluating cases of occult spinal dysraphism. Nat Med 1, Fetal spina bifida surgery. Granberg CF expert opinion. Sleep-disordered breathing in patients with myelomeningocele.
Shepard CL, et al. Swaroop VT, et al. At the L5-L6 and cranial L6 vertebral levels a division of the spinal cord was observed consistent with a segmental type II split cord malformation diplomyelia. Cases of spinal dysraphism are rare, even in newborns with cutaneous stigmas. In this abnormality, the spinal cord is lowand anchored by the lipoma . The incidence of these defects shows disrafla geographical variation from 0. CASE REPORT A five-day-old white female neonate was sent to our service for transfontanellar ultrasonography to be performed, because of the presence of cutaneous stigmas in the lumbar region.
