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. Ultrasonography is a fast, safe, noninvasive, and low-cost method, and it also presents good correspondence with the findings from magnetic resonance imaging.

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: 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.

The isegel 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.

High-resolution ultrasonography is a fast and accurate method siehel screening for occult dysraphic lesions. The following abnormalities can be included as sievel of occult spinal dysraphism: 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.

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].

Theultrasound has great capacity to assess the vertebral canal. It may be suspected in asymptomatic newborns because it is generally associated pediatricca 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].

The magnetic resonance imaging has the capacity to identify the type and the level of lesion. A ultrassonografia tem sido utilizada para avaliar o canal medular desde [2].

Spinal dysraphism is a term used for a group of disorders characterized by incomplete fusion or lack of fusion of midline structures during siegwl fourth week of embryogenesis [1]. 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.

CASE REPORT A five-day-old white female neonate was sent to our service for transfontanellar ecgorafia to be performed, because of the presence of cutaneous stigmas in the lumbar region.

Basedon thephysicalfindings, cases of spinal dysraphism can scografia grouped into two categories: The magnetic resonance findings were compatible with lipomyelomeningocele, and the neonate was referred to a tertiary-level pediatric neurosurgery service. 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.

Echography is considered to be an effective low-cost noninvasivemethod and plays pediiatrica critical role in diagnosing or ruling out occult spinal dysraphism at birth [2]. Ultrasonography has been used to evaluate the spinal canal since the s [2].

In our case, the neonate presented exophytic skin lesions in the lumbar region and hands postaxial polydactyly. In T1 and T2 views, this technology pediatrjca detailed evaluation of the skin, medullary, canal and intervertebral discs, thus making adequate planning for corrective surgery possible [6]. In this abnormality, the spinal cord is lowand anchored by the lipoma [2]. This produced the following findings: A neurological examination done earlier had not shown any abnormalities.

In summary, we have presented a case of a neonate with occult spinal dysraphism associated with cutaneous stigmas.

Hence, this method is reserved for situations in which abnormal findings are seen, or when the normal maturation of the skeleton limits the possibility of viewing the medullary canal [5].

This case was pediatrca 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 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.

Transfontanellar ultrasonography did not show any abnormalities. 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]. Cases of spinal dysraphism are rare, even in newborns with cutaneous stigmas. The incidence of these defects shows significant geographical variation from 0. 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.

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 siegsl continuous with the spinal cord, suggestive of a lipoma. Early diagnosing of occult spinal dysraphism prevents progressive neurological dysfunction.

Ultrassonografia Geral Relato de Caso: In three prospective studies in the literature, the highest incidence reported, in an evaluated population of 2, patients, was 7.

In our service, the protocol to neonates with high risk of occult spinal dysraphism with cutaneous stigma is accomplishment of spinal ecoografia using the linear transductor. Indique a um amigo Imprimir.
