Diastematomyelia a rare ultrasound diagnosis of spinal dysraphism
Ultrasound in Medicine and Biology, 2019Co-Authors: Debbie SladeAbstract:Introduction Diastematomyelia is a rare congenital anomaly where there is complete or partial duplication of the spinal cord as a result of a fibrous, cartilaginous or osseous spur. By 1994 only 100 cases had been reported worldwide. Diagnosis, if prenatal, is usually late 3rd trimester. This poster depicts a case study illustrating ultrasound appearances at 17 weeks gestation and prenatal diagnosis of Diastematomyelia at 24 weeks describing Epidemiology, Presentation, Associated Anomalies, Ultrasound appearances, Treatment and Prognosis. Rationale Due to the infrequent presentation and low recorded incidence of Diastematomyelia, limited literature is available on this condition. The purpose of this poster is to rectify this dilemma. Objectives 1. To raise awareness of the sonographic appearance of the extremely rare Diastematomyelia. 2. To disseminate the importance of an early diagnosis to promote ‘Best Practice Care’ and better patient outcomes. 3. To encourage sonographers to be vigilant and ensure thorough scanning. Method -A thorough obstetric ultrasound examination concentrating on morphology was performed utilising a Toshiba Aplio unit and 10 MHZ and 3.5MHZ curved array transducers. -Maternal and fetal structures were interrogated and documented paying particular attention to the transverse, longitudinal and coronal images of the fetal spine, skin-line and fetal cranium when a spinal abnormality was suspected. -Ultrasound appearances were compared with normal anatomy. Results Identification of an additional spinal cord posterior ossification centre is pathognomic for ultrasound antenatal diagnosis of Diastematomyelia. Conclusions The resultant significance of this poster research is to promote earlier diagnosis of this fetal anomaly and associated abnormalities assisting parents with informed decisions concerning obstetric care if their baby is affected by Diastematomyelia.

thoracic Diastematomyelia with concurrent intradural epidermoid spinal cord tumor and cervical syrinx in an adult case report
Journal of Neurosurgery, 2002Co-Authors: Jason P Sheehan, Jonas M. Sheehan, Beatriz M S Lopes, John A JaneAbstract:✓ Diastematomyelia is a rare entity in which some portion of the spinal cord is split into two by a midline septum. Most cases occur in childhood, but some develop in adulthood. A variety of concurrent spinal anomalies may be found in patients with Diastematomyelia. The authors describe a 38-year-old right-handed woman who presented with a 7-month history of lower-extremity pain and weakness on the right side. She denied recent trauma or illness. Sensorimotor deficits, hyperreflexia, and a positive Babinski reflex in the right lower extremity were demonstrated on examination. Neuroimaging revealed Diastematomyelia extending from T-1 to T-3, an expanded right hemicord from T-2 to T-4, and a C6–7 syrinx. The patient underwent T1–3 total laminectomies, resection of the septum, untethering of the cord, and excision of the hemicord lesion. The hemicord mass was determined to be an intramedullary epidermoid cyst; on microscopic evaluation the Diastematomyelia cleft was shown to contain fibroadipose connective t...

adult presentation of spinal dysraphism and tandem Diastematomyelia
The Spine Journal, 2007Co-Authors: Paul Porensky, Kenji Muro, Aruna GanjuAbstract:Abstract Background context Diastematomyelia is a split-cord malformation often accompanied by other cord or column anomalies. Purpose To report on an adult patient with Diastematomyelia and discuss the embryological basis and related developmental sequelae of this split-cord malformation. Study design Case report. Methods A summary of the management of a 54-year-old woman with recent clinical symptomatology related to an undiagnosed split-cord malformation is presented with accompanying literature review. Results A rare adult presentation of Diastematomyelia with accompanying intradural extramedullary epidermoid tumor was repaired with resection of the soft-tissue mass and excision of the fibro-osseous septum. Conclusion Initial presentation of Diastematomyelia is rarely seen in adults; accompanying pathology includes scoliosis, tethered cord, and intradural tumors. Effective treatment involves identification of the primary pathology.

prenatal diagnosis of Diastematomyelia and tethered cord a case report and review of the literature
Ultraschall in Der Medizin, 2007Co-Authors: H Struben, E Visca, Wolfgang Holzgreve, A Kang, P Hetzel, J Schneider, S TercanliAbstract:Diastematomyelia is a rare form of occult spinal dysraphism. It is characterized by longitudinal clefting and separating of the spinal cord by a bony or fibrous spur. Diastematomyelia is associated with other anomalies, i. e. spina bifida, scoliosis, visceral malformations or anomalies of the overlying skin. Prenatal diagnosis is based on fetal ultrasound supplemented by fetal MRI. We present a case of Diastematomyelia and prenatal diagnosis in the 23rd gestational week using routine ultrasound scanning and confirmation by fetal MRI. After vaginal delivery at term, the child's development is normal. Prenatal diagnosis of isolated Diastematomyelia is challenging. Management and prognosis are still controversial as only few cases have been reported. Affected fetuses might benefit from early diagnosis enabling surgical intervention before the development of neurological sequelae.

Diastematomyelia and tumor in adults report of two cases and literature review
Spine, 2010Co-Authors: P Conti, Ron Tenenbaum, Matteo Capozza, H Mouchaty, Renato ContiAbstract:Study Design. Case report and review of the literature. Objective. To report on 2 rare cases of association of Diastematomyelia with dysembryogenetic tumors and revision of the literature. Summary of Background Data. Diastematomyelia is an occult spinal diastrophism pathologically characterized by a clefting of the spinal cord with/without its overlying structures. It is often associated with vertebral bony abnormalities, cutaneous lesions, myelomeningocele, hydrocephalus, hydromyelia, Chiari syndrome or Klippel-Feil syndrome. The association of Diastematomyelia with dysembryogenetic spinal tumors in adults is extremely rare. Only 13 cases were detected in a literature review since 1951. We report on our experience with 2 new cases. Methods. An 87-year-old man and a 38-year-old woman presented to our department with incomplete cauda equina syndrome. Both patients underwent complete preoperative imaging. Complete surgical removal of the tumor was performed. Details of these were compared with the ones encountered in literature. Results. Both patients presented complete recovery in the follow-up. From the review of 15 adults described in literature including the present cases, the age ranged between 11 and 87 proving an open rage of onset of symptoms. Conclusion. The results of surgery were unclear in literature. In our experience, radical surgery was feasible and good clinical results were obtained.
