Introduction: MRI plays an important role in characterising spinal dysraphisms.The reason behind this is quality of MRI showing very high contrast resolution of soft tissuesand the ability to detect fat in the lesion.T2 weighted images provide excellent contrastbetween the sub-arachnoid spaces and neural tissue while evaluating spinal dysraphisms.Objectives: To determine the frequency of rare disorders of spinal dysraphism in view of MRIfindings of spinal dyspharism patients. Study Design: retrospective. Duration: the study wasconducted from 1st September 2015 to 30th November 2015. Settings: Radiology department,Allied hospital Faisalabad. Methods: A total of 20 consecutive pediatric age group patientspresented with clinical suspicion of spinal dysraphism were included. MRI L/S spine was carriedout on 1.5Tesla Philips and diagnosis of various disorders of spinal dysraphism was made.Conclusion: MRI is the first choice examination for the detection of occult spinal dysraphism.Its timely diagnosis improving surgical & medical outcome as well as better & long term careof patients with spinal dysraphism. Majority of patients in the current study had tethered cord(75%), myelomeningocele (20%), myelocele (10%), lipomyelocele (10%) Dermal sinus tract(10%) & diastematomyelia (10%) followed by associated spinal lipomas (5%), caudal agenesis(5%) & anterior meningocele (5%).

Dermal Sinus Tract

Dermal sinus tracts (DSTs) are an uncommon form of occult spinal dysraphism that is attributed to incomplete neural tube closure during fetal development. Dermal sinus tracts are found along the midline neuroaxis from the nasion to the coccyx, but they most commonly appear in the lumbar region. Dermal sinus tracts are more commonly associated with other developmental abnormalities such as skin tags, naevi, spinal dermoid cysts, meningocoele, lipomas and spinal cord tethering, and can be complicated by cerebrospinal fluid drainage, shedding of keratin from the epithelialized tract, and infection such as meningitis.

OBJECTIVE Cutaneous stigmata or congenital anomalies often prompt screening for occult spinal dysraphism (OSD) in asymptomatic infants. While a number of studies have examined the results of ultrasonography (US) screening, less is known about the findings when MRI is used as the primary imaging modality. The object of this study was to assess the results of MRI screening for OSD in infants. METHODS The authors undertook a retrospective review of all infants who had undergone MRI of the lumbar spine to screen for OSD over a 6-year period (September 2006–September 2012). All images had been obtained on modern MRI scanners using sequences optimized to detect OSD, which was defined as any fibrolipoma of the filum terminale (FFT), a conus medullaris ending at or below the L2–3 disc space, as well as more complex lesions such as lipomyelomeningocele (LMM). RESULTS Five hundred twenty-two patients with a mean age of 6.2 months at imaging were included in the study. Indications for imaging included isolated dimple in 235 patients (45%), asymmetrically deviated gluteal cleft in 43 (8%), symmetrically deviated (Y-shaped) gluteal cleft in 38 (7%), hemangioma in 28 (5%), other isolated cutaneous stigmata (subcutaneous lipoma, vestigial tail, hairy patch, and dysplastic skin) in 31 (6%), several of the above stigmata in 97 (18%), and congenital anomalies in 50 (10%). Twenty-three percent (122 patients) of the study population had OSD. Lesions in 19% of these 122 patients were complex OSD consisting of LMM, dermal sinus tract extending to the thecal sac, and lipomeningocele. The majority of OSD lesions (99 patients [81%]) were filar abnormalities, a group including FFT and low-lying conus. The rate of OSD ranged from 12% for patients with asymmetrically deviated gluteal crease to 55% for those with other isolated cutaneous stigmata. Isolated midline dimple was the most common indication for imaging. Among this group, 20% (46 of 235) had OSD. There was no difference in the rate of OSD based on dimple location. Those with OSD had a mean dimple position of 15 mm (SD 11.8) above the coccyx. Those without OSD had a mean dimple position of 12.2 mm (SD 19) above the coccyx (p = 0.25). CONCLUSIONS The prevalence of OSD identified with modern high-resolution MRI screening is significantly higher than that reported with US screening, particularly in patients with dimples. The majority of OSD lesions identified are FFT and low conus. The clinical significance of such lesions remains unclear.

Spinal Dermal Sinus

Spinal dermal sinus tract is a rare form of spinal dysraphism that presents occasionally with signs of spinal tethering and rarely with repeated bouts of bacterial meningitis or fulminant pyogenic infection of the conus medullaris or cauda equina leading to serious loss of neurologic function. Physical examination is crucial to accurately diagnose cutaneous findings such as the presence of a pit or tract, in order to avoid subsequent neurological sequelae. Spinal MR imaging is the only definitive imaging modality for the diagnosis of spinal dermal sinus tract and surgical planning for its excision. Total removal of all dermoid tract material is necessary to prevent recurrence. Careful peri-operative assessment and long-term follow-up will optimize outcomes and minimize complications.

Spinal epidermoid cyst is a rare entity. It may be congenital with associated spinal dysraphism such asspina bifida ,dermal sinus tract and other neural tube defects or acquired due to repeated lumbar puncture and trauma. Congenital spinal epidermoid cysts without spinal dysraphism are rare. Here we are reporting a rare and interesting case of thoracic extramedullary intradural epidermoid cyst with no associated features of spinal dysraphism or history of iatrogenic trauma in a young male patient.

In this review article, a overview is given of the congenital pathologies of vertebrae in the dog. These pathologies are common in dogs and can be divided in two major groups: neural tube defects or spinal dysraphism, such as spina bifida with or without meningocoele and dermal sinus tract, and congenital anomalies of the vertebral column. The latter group can be subdivided in malformations originating in the embryonic period of development, such as butterfly vertebra, mediolateral wedged vertebra and transitional vertebra, or in the foetal period, such as block vertebra and dorsoventral wedged vertebra. Congenital vertebral anomalies can be incidental findings on radiographs or CT, but sometimes they can be the underlying cause of a clinical, mostly neurological problem. Due to pressure on the spinal cord, symptoms, such as pelvic limb ataxia, paresis, loss of spinal reflexes, incontinence and atrophy of the pelvic limbs may occur.
