“…Surgical resection was performed, and the pathologic confirmation was mature teratomas [ 4 ]. Coulibaly et al [ 7 ] also reported a strong contrast-enhancing mass with dense calcification in the posterior fossa. It was diagnosed as meningioma preoperatively according to radiographic findings.…”

“…The occurrence of posterior fossa teratomas in adulthood is extremely rare. Only several cases have been reported thus far in the literature 1,[3][4][5][6][7][8]10,13,16,[18][19][20][21][22][23][24] . The prognosis and clinical, histological, and radiographic features of posterior fossa teratomas are unknown.…”

“…Teratomas account for 0.1–1.5% of all intracranial tumors and 2–4% of all intracranial tumors in children [ 3 , 7 , 9 , 20 ]. They usually occur near the midline and demonstrate two peaks by age distribution—during the neonatal/infancy period and between the age of 5–14 years [ 3 , 11 , 15 ].…”

The occurrence of posterior fossa teratomas in adulthood is extremely rare. In this study, we aimed to report our experience with two cases of posterior fossa mature teratoma in adults who underwent surgical resection. We also performed a systematic review of published papers available to date. Methods : We retrospectively reviewed the electronic medical records of patients who had onset of posterior fossa teratomas in adulthood at our institute between 1995 and 2020. We evaluated the clinical, radiographic, and pathological features of mature teratomas at the posterior fossa in adulthood. Furthermore, we searched the PubMed, EMBASE, and Web of Science database and reviewed published articles. Results : We found 507 articles on database review; of them, 102 were duplicates and 389 were excluded based on the inclusion criteria. Finally, 16 cases of posterior fossa from the web search and related articles. Subsequently, we added two cases that underwent surgery at our institute. We analyzed a total of 18 cases of mature teratomas. Headache was the most common (55.6%) symptom. The teratomas showed heterogeneous signals on magnetic resonance imaging. Thirteen patients (72.2%) had lesion at midline, five patients (27.8%) had calcification. Surgical resection was performed in all patients. No studies reported recurrence after resection. Conclusion :The occurrence of posterior fossa teratomas in adulthood is difficult to diagnose at the initial stage. Radiographic diagnosis alone can lead to misdiagnosis. Pathological confirmation is essential. Surgical resection is a curative option for posterior fossa teratomas in adulthood.

“…The first report of a teratoma located in the midline posterior fossa was in 1912 [10,11]. To the best of our knowledge, 15 cases of mature cystic teratoma was located inposterior fossahas been reported in English literature [12]. Approximately one half of all childhood brain tumor arise in the posterior fossa [13].…”

Intracranial mature teratoma is a very rare neoplasm. Its location in posterior fossa of cranium is extremely rare, only few cases have been reported in English literature. Though rare, it nevertheless warrants greater emphasis than it receives in the literature. The authors report a case of mature cystic teratoma in posterior cranial fossa in a 5 month old female child. On MRI examination heterogeneously enhancing solid cystic lesion measuring 4.2x4.0x3.9 cm was noted in posterior fossa involving left cerebellar hemisphere. On histopathological examination confirm diagnosis of mature cystic teratoma was established.

“…One case was a posterior fossa tumor mimicking a meningioma and another case was teratoma and meningioma in the temporoparietal region. The remaining 6 cases were all gonadal teratomas with meningioma [75][76][77][78][79][80][81][82]. The clinical and pathological characteristics of these meningiomas is presented in Table 5.…”

Extracranial meningiomas have been reported for decades now and have been described in the head and neck; calvarial, nasal cavity, paranasal sinuses, nasopharynx, parotid gland and in various remote anatomical locations systemically. The presence of microanatomical structures for all intents and purposes resembling and having the histopathological characteristics of meninges outside of the central nervous system meninges is uncommon but well-documented. Typically, these lesions are found in the lung or part of hamartomatous/choristomatous lesions and frequently occur in the head and neck anatomical region. The lesion first described by Suster and Rosai termed \"hamartoma of the scalp with ectopic meningothelial elements\" is the prototypical example of lesions with meningothelial elements. We have described recently a similar hamartomatous lesion with meningothelial elements occurring in the tongue. In this chapter, we will review the clinicopathological features of ectopic meningiomas and lesions that contain meningothelial elements and their possible pathogenesis.
