This feature was approximately 2 cm in length andwas associated with violaceous cutaneousmaculae Figures 1 a and 1 b and polydactyly on the hands and feet Figures 1 c and 1 d. The following abnormalities can be included as forms of occult spinal dysraphism: Transfontanellar ultrasonography did not show any abnormalities. A five-day-old white female neonate was sent to our service for transfontanellar ultrasonography to be performed, because of the pediaatrica of cutaneous stigmas in the lumbar region.
The diagnostic hypothesis was that a defect of the medullary canal was present in the region of the cutaneous stigma, with anchored spinal cord and an intracanal solid medullary formation with apparent peripheral invasion that was continuous with the spinal cord, suggestive of a lipoma. In our case, the neonate presented exophytic skin lesions in the lumbar region and hands postaxial polydactyly.
Spinal dysraphism is a term used for a group of disorders characterized by incomplete fusion or lack of fusion of midline structures during the fourth week of embryogenesis . The magnetic resonance findings were compatible with lipomyelomeningocele, and the neonate was referred to a tertiary-level pediatric neurosurgery service.
Images in B and pediatriva Doppler modes were obtained.

The magnetic resonance imaging has the capacity to identify the type and the level of lesion. Some stigmas have been proven to present greater risk of occult spinal dysraphism, such as deep or atypical sacrococcygeal dimples, hemangiomas, ppediatrica aplasia, subcutaneous masses, and exophytic skin lesions such as tails and hair tufts. The echographic findings suggestive of occult spinal dysraphism include a low position for the medullary cone, bulbous medullary cone, thick filum terminale, dorsal attachment of the spinal cord, and loss of cardiorespiratory pulsatory movement of the spinal cord .
This produced the following findings: Baixe o PDF deste ecogafia. Ultrassonografia Geral Relato de Caso: Theultrasound has great capacity to assess the vertebral canal.

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. Occult spinal dysraphism is defined as a group of dysraphic conditions present below an intact cover of dermis and epidermis.
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.
Here, we present a case of a five-day-old neonate with occult dysraphism of lipomyelomeningocele type who presented cutaneous stigmas, and we demonstrate the main ultrasonographic and magnetic resonance findings from the spine. Lipomyelomeningocele periatrica a form of spinal dysraphism in which the lipoma invades the dural sac, and it may envolve the nerve roots and medullary cone . 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.
Ultrasonography is a fast, safe, noninvasive, and low-cost method, and it also presents good correspondence with the findings from magnetic resonance imaging. In this abnormality, the spinal cord is lowand anchored by the lipoma .
Basedon thephysicalfindings, cases of spinal dysraphism can be grouped into two categories: Cases of multiple stigmas comprise another group at risk . Cases of spinal dysraphism are rare, even in newborns with cutaneous stigmas. Early diagnosis of spinal dysraphism is very important in order to minimize the sequelae that occur in patients who are not diagnosed before the growth spurt, who may suffer neural disorders due to medullary ischemia.
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. Physical examination on the newborn showed a skin appendage resembling a tail, on the midline in the lumbosacral region.

Atendimento ao Aluno 11 pediatricx Agendamento de exames 11 High-resolution ultrasonography is a fast and accurate method for screening for occult dysraphic lesions. In T1 and T2 views, this technology enables detailed evaluation of the skin, medullary, canal and intervertebral discs, thus making adequate planning for corrective surgery possible .

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: However, detecting this condition in neonates is difficult since the neurological eecografia in these patients are not apparent. In three prospective studies in the literature, the highest incidence reported, in an evaluated population of 2, patients, was 7. High-resolution ultrasonography using a linear transducer made it possible to identify and characterize the lesion, and magnetic resonance imaging confirmed pfdiatrica type of lesion lipomyelomeningocele and enabled adequate surgical planning.
The incidence of these defects shows significant geographical variation from 0. Because of the possibility of irreversible sequelae through delayed diagnosis, a screening method for patients at high risk of occult spinal dysraphism becomes necessary .
Its pediatria is greater among females and in poor people . In order to obtain additional information to elucidate the diagnosis, magnetic resonance imaging was performed on the spine. It is therefore more difficult to diagnose on antenatal ultrasonography. Of ecohrafia, only 5. 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 .
