Abstract
The medulla oblongata is one of the rarest sites of occurrence for germ cell tumors (GCTs) of the central nervous system. As there is scant data regarding epidemiology, clinical presentations, optimal intervention, and long-term prognosis, we aimed to delineate the features of this rare entity by presenting our representative case and performing a quantitative review of the literature. A 24-year-old woman presented to our department with vertigo and swallowing difficulties. Magnetic resonance imaging revealed a homogenously enhanced exophytic lesion arising from the medulla oblongata and extending to the fourth ventricle. Surgical resection was performed and a histological diagnosis of pure germinoma was made. The patient underwent chemotherapy and whole-ventricular irradiation. No recurrence has been experienced for 4 months after the surgery. According to the literature, the prognosis of GCTs at the medulla oblongata seems no worse than those at typical sites. Striking features including occurrence at an older age, female preponderance, and a predominance of germinoma were noteworthy. The pattern of local recurrence suggests extensive radiation coverage is not a prerequisite. Special attention is needed for cardiac and respiratory functions as the main factors eliciting mortality.

Abstract
Background Intracranial germinomas are rare tumors, accounting for 0.5-2% of primary intracranial neoplasms. While they typically occur in the pineal gland, suprasellar region, basal ganglia, and thalamus, germinomas arising in the medulla oblongata are exceptionally rare. Diagnosis of medulla oblongata germinoma is challenging, potentially leading to misdiagnosis and poor prognosis. Case Description We present a case of a 29-year-old man complaining of left leg numbness. Radiological findings revealed a contrast-enhanced lesion in the medulla oblongata. The patient underwent tumor biopsy, and intraoperative pathological diagnosis (IOD) suspected the diagnosis of medulla oblongata germinoma. He underwent chemoradiotherapy after confirming the diagnosis of germinoma. Intracranial germinoma arising in the medulla oblongata differs from germinomas in other locations due to its higher incidence in individuals in their 20s and a slight female predominance. Conclusion When encountering lesions in the medulla oblongata, germinoma should be considered as one of the differential diagnoses, and surgical strategies including IOD should be planned accordingly.

Abstract
Eating disorders caused by brain tumors are infrequently seen. Recent studies revealed that a neurocircuit from the nucleus tractus solitarius of the medulla oblongata to the hypothalamus participates in the control of appetite. Among brain tumors, those located in the brain stem, especially a solitary one in the medulla oblongata, are rare. Tumors in the brainstem are generally considered gliomas, and with the difficulty in reaching the lesion, treatment without histological confirmation is often performed. However, there are a few reported cases of medulla oblongata tumors other than gliomas. We describe a case of a 56-year-old man who presented with persistent anorexia. Magnetic resonance images revealed a solitary tumor in the medulla oblongata. After several examinations, craniotomy for the biopsy of the tumor using the cerebellomedullary fissure approach was carried out and primary central nervous system lymphoma (PCNSL) was histologically proven. The patient was treated with effective adjuvant therapy and was discharged home after he recovered from the symptoms. No tumor recurrence was recognized 24 months after surgery. A PCNSL arising only from the medulla oblongata is very rare, and anorexia can be an initial symptom of a tumor in the medulla oblongata. Surgical intervention is safely achieved and is a key to a better clinical outcome.

Abstract
Yolk sac tumor (YST) is a rare primary brain tumor that occurs almost exclusively in patients under 30 years old. Intracranial germ cell tumors are most frequently located in the pineal and suprasellar region. Medulla oblongata YSTs are particularly rare. Extragonadal YSTs may be difficult to diagnose because of their characteristics, such as the rarity and variety of growth patterns. Furthermore, they are known to have a very poor prognosis. We herein report a case of YST of the medulla oblongata in a 50-year-old woman. She was followed up for 18 months without any tumor recurrence.

Abstract
BACKGROUND Primary central nervous system germinomas of the medulla oblongata are extremely rare and usually have been found in young female Asian patients. The authors present an illustrative case of a patient who presented with severe medullary and posterior cord syndrome, the first South American case published to date, to the authors’ knowledge. OBSERVATIONS Initially, the radiological differential diagnosis did not include this entity. The lesion was located at the obex and exhibited a well-delineated contrast enhancement without hydrocephalus. An emergency decompressive partial resection following functional limits was performed. After histological confirmation, radiotherapy was indicated, with complete remission achieved at a 6-month follow-up. The patient, however, continued to have a severe proprioceptive disorder. The literature review identified 21 other such patients. The mean age for this location was 23 years, with a strong female and Asian origin predilection. All tumors exhibited contrast enhancement, and only one presented with hydrocephalus. LESSONS In the absence of elevated tumor markers, radiological clues such as a well-delineated, contrast-enhanced lesion arising from the obex, without hydrocephalus, associated with demographic features such as young age, female sex, and Asian heritage, should evoke a high level of suspicion for this diagnosis. Gross total resection must not be attempted, because this tumor is potentially curable with high-dose radiotherapy.

Abstract
Intracranial germinomas mostly occur in teenagers and young adults. The common sites are pineal and suprasellar regions. Males with Klinefelter syndrome, compared with males without chromosomal abnormalities, are known to have a higher incidence of developing pineal or suprasellar germinomas. As for germinoma in the medulla oblongata, this is rare, with only 21 previous cases reported. Due to the rarities, any relationship between people with Klinefelter syndrome and medulla oblongata germinomas remains undetermined. We present a rare case of medulla oblongata germinoma in a 25-year-old man. It is the second case of medulla oblongata germinoma in association with Klinefelter syndrome. We emphasize the importance of karyotyping in every case of germinoma, especially those with intracranial germinomas at atypical locations.

Abstract
BACKGROUND Germinomas are rare intracranial lesions, with medulla germinomas being reported in only approximately 20 cases to date. These tumors are extremely sensitive to radiotherapy, and knowledge of them can allow for accurate diagnosis as well as significantly impact treatment and prognosis. CASE DESCRIPTION We present a case of medullary germinoma and review the cases previously reported in the literature. CONCLUSIONS A few imaging characteristics are noted in multiple cases, such as cystic components, enhancement, and absence of hydrocephalus. These features can provide clues to diagnosis of this rare entity.

Abstract
INTRODUCTION Extragonadal germinomas rarely emerge from the brain stem; however, proper diagnosis and treatment can result in favorable prognosis. Unfortunately, the preoperative diagnosis of medulla oblongata germinoma is difficult due to insufficient clinical signs and symptoms that are specific to this diagnosis. Case Representation: We present a 12-year-old male patient with an intra-fourth-ventricular germinoma, derived from the medulla oblongata, with no abnormalities in the supratentorial region. The germinoma was initially assessed by advance MRI sequences, including diffusion-weighted imaging, T1 perfusion, and spectroscopy. CONCLUSION In summary, although existing imaging technologies cannot completely distinguish germinomas from other primary brain neoplasms in the fourth ventricle, in patients aged between 12 and 40 years, a small mass on the dorsal side of medulla oblongata that emerges into the fourth ventricle and is characterized by homogeneous contrast enhancement, the absence of calcification and hemorrhage, and the lack of hydrocephalus should be considered for a potential medulla oblongata germinoma diagnosis.

Abstract
Pineal germ cell tumors (GCTs) are primarily seen in pediatric and Asian populations. These tumors are divided into germinomatous and non-germinomatous GCTs (NGGCTs). GCTs are thought to arise by misplacement of totipotent stem cells en route to gonads during embryogenesis. Intracranial GCTs display an affinity to develop along the pineal-suprasellar axis and have variable manifestations dependent upon the location of the tumor. Management and outcomes are driven by histopathologies. In this study, we highlight two cases of pineal GCTs and present a review of the literature with an emphasis on histopathologies and biomarkers.

Abstract
BACKGROUND The medulla oblongata is the lower half of the brainstem. It contains the cardiac, respiratory, vomiting, and vasomotor centers and deals with autonomic functions such as breathing, heartbeat, and blood pressure. Primary medulla oblongata germinoma is very rare and less than 20 cases have been reported in the English literature. CASE DESCRIPTION A 22-year-old female without any particular past medical history presented to us in October 2012 with the chief complaint of dyspnea and frequent choking for 1 month. Neurological examination revealed lower cranial nerve palsies and nystagmus. Her brain computed tomography (CT) and brain magnetic resonance imaging (MRI) demonstrated a mass lesion at the dorsal surface of medulla oblongata with extension into the inferior fourth ventricle and foramen magnum. She underwent bilateral suboccipital craniotomy and C1 laminoplasty with the grossly total resection of the tumor. The histological examination of the tumor proved germinoma. Postoperative adjuvant radiotherapy was arranged. The latest brain MRI and whole spine MRI done 1 year after surgery showed neither residual nor recurrent tumor in the whole axis. She is regularly followed-up at our outpatient department and is doing well except having left vocal cord palsy, which occurred before surgery. CONCLUSION Medulloblastoma, ependymoma, glioma, hemangioblastoma, and cavernous angioma are common intraaxial tumors in the medulla oblongata and fourth ventricle. Intracranial germ cell tumors originate from extragonadal seminal cells and have been found in 0.4-3.4% of patients with primary central nervous system (CNS) tumors in Western countries, while the incidence is reported to be 5-8 times greater in Japan and the Far East. Although germinoma of medulla oblongata is rare and difficult to diagnose preoperatively, it should be included in the differential diagnosis of medulla masses with fourth ventricle extension, especially in Asian population.
