“…In a recent paper, Mostafavi et al show that granulocytic sarcoma, although more frequent on the thoracic level, can also mimic a cauda equina tumor [38]. Some exophytic tumors of the conus medullaris can also do this, like that in the case reported by Nicoletti [39] or extremely rare tumors like the multiple astrolipoma described by Roda [40], the neurocytoma described by Stephan et al [41], and the intravascular papillary endothelial hyperplasia described by Taricco et al [42]. In these unusual cases, only surgical resection and pathological examination will disclose the diagnosis.…”

Large series of cauda equina tumors in adults are seldom reported. This French series retrospectively reviews 231 cases collected for the congress of the Societe Francaise de Neurochirurgie in 1996. The authors first analyze this series and then discuss the pertinent literature. Schwannoma was the most frequent benign tumor in this series, followed by ependymoma. Very few malignant tumors were recorded; these were usually malignant neurinomas nearly always in neurofibromatosis patients. Some other rare tumors were also recorded, including paragangliomas. This series confirms the importance of the pretherapeutic neurological status in functional prognosis. All schwannomas can be cured, while ependymomas and paragangliomas may recur after a very long delay. Surgery must be as complete as possible, since adjuvant therapies are proven to have little efficacy. This type of tumor requires very long follow-up. Prognosis is good for hemangioblastomas. Sphincter dysfunctions carries a poor prognosis and may appear after primary surgery, more often after treatment of recurrences.

“…Russell and Rubinstein defined a teratoma as "a tumor that contains ectodermal, mesodermal, and endodermal elements" [14]. In the literature, 18 cases of spinal intramedullary teratoma [1,2,3,4,5,6,7,8,9,10,11,12,13,15], including the present case, have been presented ( Table 1). The most frequent site of intramedullary teratoma was the conus medullaris (70.6%), as in our case.…”

“…Spinal intramedullary teratoma is rare [1,2,3,4,5,6,7,8,9,10,11,12,13,15], and there is some confusion about the use of the term teratoma. In some reports, terms such as teratoid, teratoid cyst, teratomatous cyst, teratoma, and cystic teratoma have been used for the same category, and several hypotheses have been presented for the pathogenesis of this disease [1,9,16].…”

Spinal intramedullary teratoma is a rare tumor. We report a case of intramedullary teratoma of the conus medullaris with spina bifida. A 5-year-old boy was admitted to our hospital for removal of a lumbosacral tumor sited in an intramedullary location at the conus medullaris, which was totally resected with neuroendoscopic assistance. The pathological diagnosis was mature teratoma consisting of three germ cell layers. The pathogenesis of spinal intramedullary teratoma is discussed with special reference to spina bifida.

“…MRI is regarded as the gold-standard technique for the preoperative diagnosis of a teratoma, given the differential intensity of the mass components and the presence of fatty tissue (13,17). In our case, preoperative MRI defined the morphology and localization of the tumor in relation to the conus medullaris, leading us to suspect a teratoma.…”

Coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation in an adult: a case report

The coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation (AVM) is exceptional, which has not been reported previously in the literature. The precise mechanism of the coexistence of these conditions is not known, however, the dysembryonic origin of spinal cord teratoma and AVM seems to play a part in this process. A 34-year-old male patient was admitted with lower back pain, bilateral lower extremity numbness and weakness, and sexual disturbance. Magnetic resonance imaging (MRI) showed an AVM extended cranially from the top of a heterogeneous expansile lesion of the conus medullaris. Surgical exploration and histopathological examination revealed a mature teratoma associated with the AVM. A literature review supported the dysembryonic origin of spinal cord teratomas and AVMs. This unique case may provide insight into the etiopathogenesis of the coexistence of spinal teratoma of the conus medullaris and AVM. KeywoRds: Spinal teratoma, AVM, Conus medullaris ÖZKonus medullaris spinal teratomu ve arteriyovenöz malformasyonun (AVM) birlikte bulunması çok nadirdir ve literatürde daha önce bildirilmemiştir. Bu iki durumun birlikte bulunmasının tam mekanizması bilinmemektedir ancak spinal kord teratomu ve AVM'nin disembriyonik kökeninin bu süreçte bir rolü var gibidir. 34 yaşında bir erkek hasta bel ağrısı, bilateral alt ekstremite uyuşukluğu ve zayıflığı ve cinsel bozuklukla başvurdu. Manyetik rezonans görüntüleme (MRG) konus medullariste heterojen ekspansil bir lezyonun üzerinden kraniyal olarak uzanan bir AVM gösterdi. Cerrahi eksplorasyon ve histopatolojik inceleme AVM ile ilişkili matür bir teratom gösterdi. Literatür taraması spinal kord teratomları ve AVM'lerin disembriyonik kökenini destekledi. Bu benzersiz vaka konus medullaris spinal teratomu ve AVM'nin birlikte bulunmasının etiyopatogenezi açısından bilgi sağlayabilir.
