Akijin In our service, the protocol to neonates with high risk of occult spinal dysraphism with cutaneous stigma is accomplishment of spinal ultrasound using the linear transductor. The incidence of these defects shows significant geographical variation from 0. 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 were 1 discontinuity of the 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.

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. Atendimento ao Aluno 11 Agendamento de exames 11 However, detecting this condition in neonates is difficult since the neurological signs in these patients are not apparent.

This produced the following findings: A neurological examination done earlier had not shown any abnormalities. In our service, the protocol to neonates with high risk of occult spinal dysraphism with cutaneous stigma is accomplishment of spinal ultrasound using the linear transductor.

In T1 and T2 views, this technology enables detailed evaluation of the skin, medullary, canal and intervertebral discs, thus making adequate planning for epdiatrica surgery possible [6]. This case was different from our protocol because the neonate was referenced to realize the transfontanellar ultrasound, and only after the observation of cutaneous stigma, the protocol of occult spinal dysrapism was performed.

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 pediateica spinal cord, and loss of cardiorespiratory eecografia movement of the spinal cord [8].

Theultrasound has great capacity to assess the vertebral canal. Physical examination on the newborn showed a skin appendage resembling a tail, on the midline in the lumbosacral region. 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 [4].

Siegel — Google Books Atendimento ao Aluno 11 Pediagrica 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.

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. Echography is considered to be an pediatric low-cost noninvasivemethod and plays a critical role in diagnosing or ruling out occult spinal dysraphism at birth [2].

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 [5].

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 pediqtrica [1].

Some stigmas have been proven to present greater risk of occult spinal dysraphism, such as deep or atypical sacrococcygeal dimples, hemangiomas, cutaneous aplasia, subcutaneous masses, and exophytic skin lesions such as tails and hair tufts.

Lipomyelomeningocele is a form of spinal dysraphism in which the lipoma invades the dural sac, and it may envolve the nerve roots and medullary cone [1]. Occult spinal dysraphism is defined as a group of dysraphic conditions present below an intact cover of dermis and epidermis.

R e pela S. 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. In order to obtain additional information to elucidate the diagnosis, magnetic resonance imaging was performed on ecografoa spine.

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. High-resolution ultrasonography is a fast and accurate method for screening for occult dysraphic lesions.

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. In summary, we have presented a case of a neonate with occult spinal dysraphism associated with cutaneous stigmas. Transfontanellar ultrasonography did not show any abnormalities. The magnetic resonance imaging has the capacity to identify the type and the level of lesion.

The following abnormalities can be included as forms of occult spinal dysraphism: 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.

Cases of multiple stigmas comprise another group at risk [7]. Because of the possibility of irreversible sequelae through delayed diagnosis, a screening method for patients at high risk of occult spinal dysraphism becomes necessary [7]. Images in B and color Doppler modes were obtained. Basedon thephysicalfindings, cases of spinal dysraphism can be grouped into two categories: Its prevalence is greater among females and in poor people [2].

The neonate underwent corrective surgery and, over a six-month followup, presented normal neuropsychomotor development. The ultrasonographic findings from the spine were 1 discontinuity of the posterior bone layers in ecografoa 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.

Early diagnosing of occult spinal dysraphism prevents progressive neurological dysfunction. 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 pediatgica spinal cord, suggestive of a lipoma. 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 magnetic resonance findings were compatible with lipomyelomeningocele, and the neonate was referred to a tertiary-level pediatric neurosurgery service. In this abnormality, the spinal cord is lowand anchored by the lipoma [2]. Most Related.

Vitaur Ultrasonography is a fast, safe, noninvasive, and low-cost method, and it also presents good correspondence with the findings from magnetic resonance imaging. 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 [8]. Early diagnosis of spinal dysraphism is very important in order to minimize the sequelae that occur in patients who are not diagnosed rcografia the growth spurt, who may suffer neural disorders due to medullary ischemia. In three prospective studies in the literature, the highest incidence reported, in an evaluated population of 2, patients, was 7.
