Abstract
Mature spinal teratoma is a rare type of germ cell tumor that arises from any of the three germ cell layers (ectoderm, mesoderm, and endoderm) and consists of differentiated tissues and structures that reflect the cellular organization and morphology of normal adult tissues. It has the ability to grow independently and cause compressive symptoms when found in this rare location. In this article, we present the case of a 29-year-old male patient with the onset of neurological symptoms beginning with pelvic limb paresthesias and progressing to back pain. Magnetic resonance imaging (MRI) revealed a tumor at L1-L4, which was resected by laminotomy, and histopathology revealed a mature intradural teratoma. Fortunately, this histologic type had a good prognosis for our patient, who had a significant clinical improvement. A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology with PubMed and Google Scholar to find similar case reports and to summarize the main features of this disease, which contributes to the understanding of its diagnostic presentation, treatment, and prognosis, improving clinical practice in the management of similar cases. The rarity of this condition, together with its wide clinical heterogeneity and prognosis, underscores the importance of a thorough evaluation of cases of intramedullary lesions, where the consideration of uncommon diseases in the differential diagnosis should be highlighted.

Abstract
PURPOSE Split cord malformation (SCM) presenting concomitant with spinal teratoma without any open spinal dysraphism has rarely been reported in the literature. We aimed to make a systematic review and qualitative analysis of the literature about the topic and present the first case of SCM concomitant with spinal teratoma harboring papillary thyroid carcinoma (PTC) component. METHODS Two big search tools (Pubmed/MEDLINE) and Scopus were used. The search strategy was compatible to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An exemplary case of ours was also presented. RESULTS There were 30 patients (15 pediatric and 15 adult). Female and male distribution was even. Median age of the patients was 18 years (range = 0-66 years). The most common presenting symptoms were back pain and lower limb weakness. Spinal teratoma and SCM mostly presented at thoracic/thoracolumbar region in children and lumbar region in adults. Surgical outcome was better in the children compared to the adults. CONCLUSION Thoracolumbar region is the most common location for such entity in children, whereas lumbar region for the adults. Surgical resection should be done as much as possible under neuromonitorization. The resected material should be evaluated thoroughly not to miss any malign pathology. Surgical outcome is better when it is done at an early age.

Abstract
Intradural mature teratomas are spinal tumors containing all the germinal layers and rarely present in adulthood. This study describes an unusual case of intradural mature teratoma in a 19-year-old male who presented with persistent lower limb pain and difficulty in micturition. The magnetic resonance imaging (MRI) scan showed heterogeneously enhancing intramedullary mass in the L3-L4 vertebral region and was associated with tethering of the spinal cord. Scalloping of the posterior aspect of vertebral body and narrowing of the pedicles were present. Subtotal excision of the tumor was done because of its adherence to the conus. Attempt to completely excise such adherent intramedullary tumors can lead to permanent neurological deficits. The tissue was sent for histopathological examination which showed tissue from all the three germinal layers confirming the diagnosis. The patient showed improvement of symptoms following the surgery. This study also compared the literature of similar cases and the treatments available for this disease.

Abstract
Background Teratomas in the pediatric population are most commonly found in the sacrococcygeal region. Pediatric intraspinal teratomas, however, are an exceedingly rare central nervous system (CNS) neoplasm. The clinical presentation of these intraspinal neoplasms can vary significantly and thus can be difficult to identify in infants less than one year of age where verbal expression and motor development are still lacking. Case Description. A 7-month-old, previously healthy male presented with a thoracic scoliosis and an asymptomatic right midupper thoracic spinal prominence present since birth. MRI revealed an extensive heterogenous mass in the right epidural space from T5-T6 and the right paravertebral space, resulting in severe spinal stenosis. Outcome. Complete resection of the tumor, including a three-level neurotomy, was achieved by posterior decompression/laminectomy. The final tumor was consistent with a mature teratoma. The surgical resection was performed without any immediate complications. Conclusions Extramedullary epidural teratomas are exceptionally rare tumors in the pediatric population. Clinical presentation can be ambiguous, particularly in an infant. MRI was useful in suggesting a teratoma as a potential diagnosis and for postoperative surveillance for recurrence. However, histopathological analysis remains the gold standard for definitive diagnosis. Surgical resection is the mainstay of treatment, especially in the setting of cord compression and progressive loss of motor function. Close follow-up is crucial to monitor for progressive spinal deformity or recurrence.

Abstract
OBJECTIVE Conus medullaris teratomas are extremely rare, and the treatment experience has been limited. The purpose of the present study was to evaluate the clinical characteristics, radiological features, surgical outcomes, and prognosis of patients with conus medullaris teratoma. METHODS We retrospectively reviewed the data from 39 patients who had undergone surgical resection for conus medullaris teratomas from January 2008 to December 2018. All the operations were performed by 1 senior doctor. The clinical features, pre- and postoperative magnetic resonance imaging findings, pathological features, treatment strategies, and outcomes were analyzed. The neurological status was evaluated using the modified Japanese Orthopaedic Association scale score. RESULTS Of the 39 patients, the mean age was 30.9 years. Of the 39 patients, 20 were male and 19 were female. The symptom duration ranged from 0.3 to 252 months (mean, 61.6 months). Bladder and bowel dysfunction was the most common symptom (76.9%). Total resection was achieved in 25 patients (64.1%), subtotal resection in 11 (28.2%), and partial resection in 3 (7.7%). A mature teratoma was confirmed in all 39 patients. The neurological outcomes were improved 16 patients (45.7%), stable in 14 (40.0%), and aggravated in 5 (14.3%) at a mean follow-up of 62.7 months. Recurrence developed in 1 patient who had undergone subtotal resection. A second surgery with total resection was performed, and the patient's neurological symptoms were stable during follow-up. CONCLUSIONS Total surgical resection is the optimal treatment strategy for patients with conus medullaris teratoma. Safe maximum tumor removal and residual tumor inactivation using electrocoagulation are recommended when total resection cannot be achieved. Surgery can provide a low recurrence rate and an acceptable low complication rate.

Abstract
Teratomas are benign germ cell tumors that usually found out of their anatomical origin. Teratomas usually are found in sacrococcygeal area, gonads, mediastinum, cervicofacial region and intracranial fossa. Spinal teratomas are rare. In this study we describe a case of conus medullaris teratoma which was diagnosed based on imaging studies. The patient underwent surgery. We did bilateral laminectomy. The mass lesion had an obvious and rigid attachment to the conus medullaris. The wall of the lesion was resected as much as possible, but total resection of the lesion's wall could not be done due to changes in neural monitoring. Previous related studies are reviewed.

Abstract
PURPOSE Spinal teratomas are rare tumours noted in adults and are commonly located in the thoracolumbar region. Currently, there appears to be a lack of clear consensus regarding the management and prognosis of these lesions. A comprehensive review along with an illustrative case managed at the author's institute has been presented. MATERIALS AND METHODS Online database search was performed for literature review. RESULTS A 26-year-old male presented with acute onset neurological deficits and imaging revealed features of conus teratoma. Subtotal resection was performed and patient achieved fair recovery. Including the present one, a total of 146 cases have been reported and were analysed. Mean age was 39.6 years (range 18-85 years) and males predominated. Limb weakness and backache were the commonest symptoms. Majority of the lesions were intramedullary and located in the thoracolumbar region. Complete resection (CR) was achieved in 45% of cases. All, except one, were mature teratomas. Recurrences were noted in nine (6.1%) cases. Outcome was good/excellent in 86 (60%) and fair/poor in 26 (18%) cases. The presence of pain, absence of limb weakness and CR were significantly associated with good outcomes. Furthermore, subtotal resection (STR) had significantly higher recurrence rates than CR. Four deaths (2.7%) were noted. CONCLUSIONS Total surgical resection is the standard treatment and appears to be beneficial both in terms of outcomes and recurrences. Overall, recurrences are rare and may be managed by re-surgery. In addition, the present report is the eighth case of adult spinal teratoma with an acute onset presentation. These slides can be retrieved under Electronic Supplementary Material.

Abstract
Teratoma is a tumor that derivatives from all three primitive germ layers and spinal intramedullary teratomas are very rare lesions. The primary treatment modality for these tumors is surgical resection, and total resection should be the aim. However, subtotal resection is a valid alternative to prevent traumatizing adjacent functional neural tissue. In this report, we presented a case of a 12-year-old male patient with spinal teratoma of the conus medullaris. We describe the presentation, evaluation, and treatment of this rare disease.

Abstract
Objective Conus medullaris teratomas are very rare tumors. Traditional preoperative diagnosis depended on the findings from magnetic resonance imaging (MRI). Tractography is a novel technique that has recently been utilized to diagnose spinal cord lesions. This case report shows that fiber tractography has great potential in preoperative diagnosis and postoperative follow-up of teratomas of the conus medullaris. Methods A 50-year-old man with a conus medullaris teratoma underwent tractography with the aim of visualizing the tumor in relation to the white matter tracts. The patient underwent a T12–L2 laminectomy, and the lesion was resected. The histopathology diagnosis was of a mature teratoma. Study Design Case report. Results Diffusion tensor imaging (DTI) and tractography provide more details about the white matter tracts in relation to space-occupying lesions that may be more sensitive than conventional MRI and have recently been utilized in spinal cord lesions. Fiber tracking has the ability to visualize the integrity of the white matter tracts at the level of the conus medullaris in relation to the lesion. The tracts appeared to be displaced by the lesion at the conus medullaris. Tractography also showed no white matter tracts within the lesion. Such findings are consistent with the characteristics of a benign lesion. Exploiting tractography in this case was helpful in predicting the nature of the lesion preoperatively and in planning the surgical intervention. Conclusions Conus medullaris teratomas mostly affect adults. Patients generally present with a long history of clinical symptoms prior to diagnosis. Surgery is required for diagnosis, and the goal should be complete tumor excision without sacrificing any neurologic functions. The use of DTI and tractography, in addition to conventional MRI, has the potential to be very valuable for the diagnosis, surgical planning, and follow-up of patients with conus medullaris teratomas.

Abstract
Split cord malformation (SCM) is a rare form of spinal dysraphism in which the spinal cord is divided in the sagittal plane, forming a double neural tube. In addition to being associated with a variety of malformations, SCM may occur with spinal cord tumors, with only exceptional cases involving teratomas. As only eight patients with a teratoma associated with SCM have been reported, their presentation characteristics and treatment are currently unclear. We review the literature of all patients with SCM with concurrent spinal teratoma, discuss the potential dysembryology, and report the first case of SCM with concurrent spinal teratoma in an elderly patient. The mean age of those with concurrent SCM and teratomas was 39.4 years, with 55.6% occurring in females. The lumbar spine was the most frequent location for teratomas (66.7%), with the Type II malformation more commonly occurring with these tumors (75%). The duration of symptoms varied widely, ranging from 1 month to 5 years, with the average duration being nearly 2 years. Back pain (87.5%) and lower extremity weakness (75%) were the most common presenting symptoms. As SCM may be associated with progressive neurological deterioration and teratomas can contain immature or malignant components, surgery should be attempted with the goal of gross total resection. Nonetheless, in patients with a concurrent tumor and spinal dysraphism, spinal teratomas should be considered in the differential diagnosis. Gross total resection of these lesions may be safely achieved even in the presence of SCM using intraoperative electrophysiologic monitoring.

Abstract
PURPOSE A personal series of 131 patients with split cord malformation (SCM) operated on is presented. METHODS Age, gender, symptoms and signs, radiological and operative findings, complications, associated anomalies, outcome, and pathological specimens were analyzed. RESULTS There were 88 girls (73 %) and 43 boys (27 %). The female predominance was slightly more remarkable in type I SCMs than in type II SCMs. The presenting symptoms can be summarized as skin lesions, spina bifida aperta, scoliosis or kyphoscoliosis, sphincter disturbance, foot deformities and weakness, and/or atrophy in the lower extremities. The ages of patients with neurological deficits and orthopedic deformities were significantly older than those without deficits (P = 0.030). The duration of symptoms was longer in the patients with neurological deficits and orthopedic deformities than that in those without deficits (P = 0.00095). In six patients, composite SCMs were present. Only one patient with a type II SCM did not have an associated spinal cord lesion. A type I SCM was more frequently encountered in patients with spina bifida (P < 0.0005). Transient postoperative complications were seen in 29 patients (22 %). There was no permanent complication. Retethered cord syndrome developed in five patients with a type I SCM. CONCLUSIONS The risk of neurological and orthopedic deficits increases with the age of the patient. The risk of permanent deficit after surgery is very low. The whole spine must be examined for additional lesions. All patients should be surgically treated when diagnosed, especially before the development of orthopedic and neurological manifestations, and all associated lesions should also be treated at the same session.

Abstract
A 23-year-old Chinese male patient presented with an extremely rare case of spinal teratoma with neuronal and glial tissue components manifesting as lower back pain and radiating pain to the leg. Subtotal excision of the tumor was conducted. Histological examination revealed a mature teratoma with neuronal and glial tissue components. Initial presentation of spinal teratoma in adulthood is rare. Teratomas show a wide array of organoid tissue differentiation, but neuronal tissue component is uncommon.

Abstract
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.

Abstract
STUDY DESIGN.: Case report and literature review. OBJECTIVES.: To report the very rare case of a mature intramedullary teratoma with exophytic extension localized to the uppermost cervical spinal level in a 65-year-old woman and review the pertinent medical literature. SUMMARY OF BACKGROUND DATA.: Cervical intramedullary teratomas are extremely rare in adults, especially in patients older than 50 years. METHODS.: The patient presented with progressive ataxia, mild bilateral kinetic hand tremors, and dizziness. Magnetic resonance imaging revealed an intramedullary 1.7 x 1.3 x 2.3 cm mass at C1 with exophytic extension. A C1-C2 laminectomy and a partial suboccipital craniotomy were performed, followed by a subtotal microscopic resection of the tumor. Pathology was consistent with a mature teratoma. RESULTS.: After surgery, the patient's ataxia, tremor, and dizziness resolved almost immediately. CONCLUSION.: This report presents the very rare case of a mature intramedullary teratoma located in the upper cervical spine of an elderly patient, possibly the oldest patient documented with this type of lesion. The authors recommend a conservative subtotal surgical resection of cervical intramedullary tumors because it may improve symptoms that relate to direct mechanical cord compression and avoid further harm from a gross resection.

Abstract
BACKGROUND Spinal cord teratomas are uncommon tumours. The diagnosis is rarely suspected before surgery and final diagnosis is invariably made at histopathological examination. METHODS We retrospectively analysed our neuropathology records for the last 20 years and all patients diagnosed as spinal teratomas were retrieved. The clinical and radiological features were noted. Slides were reviewed and the diagnosis was confirmed. FINDINGS During a period of 20 years, we found 27 examples of spinal teratomas. There was a wide age range and 37.3% presented in adulthood. Male predominance was observed both in children as well as adults. The dorso-lumbar location was common in children as well as in adults but an intramedullary location, in association with a myelomeningocele and split cord malformation, was more common in children. Twenty one patients had associated features of spinal dysraphism. Of the six who were not associated with this, five were adult patients. Radiologically mixed solid and cystic morphology, fat signal and areas of calcification were seen in one third of patients. All tumours except one showed benign (mature) components. Interestingly, two lesions contained mature renal tissue: one exhibited pulmonary differentiation and one had Wilm's tumour as a component of the teratoma. In five patients the initial sections showed epidermis with skin adenexal structures and a diagnosis of dermoid cyst was suspected but serial sectioning revealed other teratomatous components. All patients were treated with surgical excision. CONCLUSION Although there are no specific features on imaging, mixed solid and cystic morphology, fat signal and areas of calcification are helpful in the pre-operative diagnosis. Most of these lesions are diagnosed on histopathological examination after surgery and therefore thorough sampling and serial sectioning are mandatory to identify all components of the teratoma in order to avoid misdiagnosis.
