Transfontanellar ultrasonography did not show any abnormalities.
Siegel – Ecografía Pediátrica
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. The ultrasonographic findings from the spine were 1 discontinuity of the posterior bone layers in the L5 siegeel 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.
The magnetic resonance imaging has the capacity to identify the type and the level of lesion.
Of these, only 5. In three prospective studies in the literature, the highest incidence reported, in an evaluated population of 2, patients, was 7.
In this abnormality, the spinal cord is lowand anchored by the lipoma . 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. 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.
Occult spinal dysraphism is defined as a group of dysraphic conditions present below an intact cover of dermis and epidermis. R e pela S. 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 . 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: 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 .
Cases of spinal dysraphism are rare, even in newborns with cutaneous stigmas. Early diagnosing of occult spinal dysraphism prevents progressive neurological dysfunction.
The incidence of these defects shows significant geographical variation from 0. Atendimento ao Aluno 11 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 .
This produced the following findings: 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 . Agendamento de exames 11 Theultrasound has great capacity to assess the vertebral canal.

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. Indique a um amigo Imprimir. In our case, ecgrafia neonate presented exophytic skin lesions in the lumbar region and hands postaxial polydactyly. Basedon thephysicalfindings, cases of spinal dysraphism can be grouped into two categories: Images in B and color Doppler modes were obtained.
We believe that ultrasonography should be ecogrfaia 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.
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. Physical examination on the newborn showed a skin appendage resembling a tail, on the midline in the lumbosacral region.

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 . Because of the possibility of irreversible sequelae through delayed diagnosis, a screening method for patients at high risk of occult spinal dysraphism becomes necessary .
The neonate underwent corrective surgery and, over a six-month followup, presented normal neuropsychomotor development. However, detecting this condition in neonates is difficult since the neurological signs in these patients are not apparent. Ultrasonography is a fast, safe, noninvasive, and low-cost method, and it also presents good correspondence with the findings from magnetic resonance imaging. 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.
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. Magnetic resonance imaging is another diagnostic imaging method for evaluating cases of occult spinal dysraphism.
It is therefore more difficult to diagnose on antenatal ultrasonography. In summary, we have presented a case of a neonate with occult spinal dysraphism associated with cutaneous stigmas. A neurological examination done earlier had not shown any abnormalities. Here, we present a case of a five-day-old neonate with occult dysraphism of lipomyelomeningocele type who presented cutaneous stigmas, and we demonstrate eiegel main pediatroca and magnetic resonance findings from the spine.
Some stigmas have been proven to present peciatrica 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.
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.

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.
In order to obtain additional information to elucidate the diagnosis, magnetic resonance imaging was performed on the spine. Echography is considered to be an effective low-cost noninvasivemethod and plays a critical role in diagnosing or ruling out occult spinal dysraphism at birth .
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 magnetic resonance findings were compatible with lipomyelomeningocele, and the neonate was referred to a tertiary-level pediatric neurosurgery service. Ultrassonografia Geral Relato de Caso: Its prevalence is greater among females and in poor people . 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 .
