Rachischisis is a neural tube defect, which occurs when the neural folds do not join at the midline and the undifferentiated neuroectoderm remains exposed. Finding site True Neural tube structure Inferred relationship Some 4
Rachischisis is a neural tube defect, which occurs when the neural folds do not join at the midline and the undifferentiated neuroectoderm remains exposed. Rachischisis totalis (holorachischisis) is the extreme form in which the entire spinal cord remains open. Finding site True Neural tube structure Inferred relationship Some 2
Rachischisis is a neural tube defect, which occurs when the neural folds do not join at the midline and the undifferentiated neuroectoderm remains exposed. Rachischisis partialis (merorachischisis) is the partial form where the spinal cord is partially closed and partially open. Finding site True Neural tube structure Inferred relationship Some 4
A rare disorder that presents as a flat neural placode (at the level of the skin of the back) that is exposed to the environment. The lack of expansion of the subarachnoid space distinguishes this lesion from myelomeningocele. Finding site True Neural tube structure Inferred relationship Some 4

A rare subtype of split cord malformation characterised by each hemicord contained in its own dural sac, typically with an intervening bony septum. Finding site True Neural tube structure Inferred relationship Some 2
Posterior meningocele is a rare neural tube closure defect characterized by the herniation of a cerebrospinal fluid-filled sac, that is lined by dura and arachnoid mater, through a posterior spina bifida and covered by a layer of skin of variable thickness, which may be dysplastic or ulcerated. The spinal cord and nerves are generally not included and function normally, although sometimes a tethered cord may be associated. They are most commonly located in the lumbar or sacral region. Finding site True Neural tube structure Inferred relationship Some 3
A rare intermediate form of open dysraphism between myelomeningocele and saccular limited dorsal myeloschisis without fulfilling the characteristics of one of these two diagnosis, characterized by stretched neurulation of spinal cord attached at the dome of a sac. Partial cerebral signs of open dysraphism can be observed and the meningocele is usually poorly epithelialized. Finding site True Neural tube structure Inferred relationship Some 3
A rare dysraphic spinal cord lipoma with characteristics of a lipomatous mass extending ventrally to the dorsal root entry zone, indicating a more severe malformation of the spinal cord. The diagnosis can be suggested on imaging but usually confirmed during surgery. Finding site True Neural tube structure Inferred relationship Some 3
A rare closed lipomatous, dysraphic malformation of the lower spinal cord characterized by extramedullary lipomatous mass attached to the conus region. The conus is dysplastic and poorly delineated. Various morphological subtypes are recognized. Possible symptoms include bowel and bladder dysfunction and neuro-orthopedic deformity of the lower limbs. Finding site True Neural tube structure Inferred relationship Some 3
A rare closed dysraphism with stalk characterised by a dorsal midline dermal sinus tract lined by keratinising stratified squamous epithelium extending to the intrathecal space. Other components such as hair follicles and shafts, mesenchymal derivatives (blood vessels and fibrous tissue) and occasionally nerve fibres can be observed. Inflamed granulation tissue containing mixed neutrophils, plasma cells, lymphocytes, and histiocytes is consistently found in the tract. It can also be associated with an intradural dermoid cyst. This malformation is at risk to cause intrathecal infections (meningitis, empyema) that justify prophylactic surgery. Finding site True Neural tube structure Inferred relationship Some 2
A rare closed dysraphism with terminal stalk with characteristics of persistant rudimentary spinal cord below conus. It contains non-functional neural tissue and is typically isolated. The diagnostic is suggested by attenuated conus without fat, further confirmed by pathological analysis (glioneuronal core with ependyma-lined lumen, nerve roots, and dorsal root ganglia). Differential diagnostic with intraoperative neurophysiological monitoring is mandatory as neuroimaging fails to distinguish it from functional conus. Finding site True Neural tube structure Inferred relationship Some 3
A rare, closed spinal dysraphism with characteristics of a myelocystocele at the termination of the spinal cord. It may be an isolated anomaly or be associated with other defects, including sacral agenesis, anorectal and genitourinary anomalies. The conus is not identifiable. The myelocystocele sac may have a significant lipomatous component (terminal lipomyelocystocele). Finding site True Neural tube structure Inferred relationship Some 4
A rare form of limited dorsal myeloschisis (LDM), with characteristics of a non-saccular cutaneous stigmata (midline skin abnormality classically dimple, pit or sometimes angioma), the stalk is attached to the cutaneous stigmata. Fibroneural stalk varies in thickness and complexity. Finding site True Neural tube structure Inferred relationship Some 3
A rare dysraphic abnormality with characteristics of a persistent connection between the neural tissue and overlying skin. The stalk-like connection consists of a fibroneural tract (mainly composed of fibrous attenuated mesenchymal tissue and neural elements without an epithelial lining) connecting the skin lesion to the underlying dorsal surface of the spinal cord. Fibroneural stalk varies in thickness and complexity, and they pass through the deep fascia, a bifid lamina/ the interspinous ligament, and the dura. It can be associated with filum anomaly. Chiari II malformation is not present. Finding site True Neural tube structure Inferred relationship Some 3
A rare form of limited dorsal myeloschisis (LDM), characterized by the stalk attached to the apex of a fully epithelialized meningocele. Chiari II malformation is not present. Finding site True Neural tube structure Inferred relationship Some 3
A very rare non-dysraphic spinal cord lipoma which is located within the spinal cord. There is no defect in the overlying dura. Finding site True Neural tube structure Inferred relationship Some 2
A rare closed spinal dysraphism with characteristics of myelocystocele located above the conus region. Also considered as a form of saccular limited dorsal myeloschisis. Finding site True Neural tube structure Inferred relationship Some 4
