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. ⋯ 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.

Case Reports
Cervical Laminoplasty for Resection of Hemorrhagic Cavernous Malformation Using a Biportal Technique.
This Video 1 presents the surgical management of a 36-year-old woman who presented with progressive weakness in her right arm associated with a pins-and-needles sensation. Magnetic resonance imaging of the cervical spine revealed a likely hemorrhagic cavernous malformation of the spinal cord at the C3-4 level. The lesion was wholly intramedullary with no presentation to the surface of the spinal cord. ⋯ After successful resection, the cavity was carefully inspected and closure of the dura was performed, followed by fixation of the osteotomy sites of the laminae at C3 and C4. The patient awoke with no new neurologic deficits and has had no evidence of lesion recurrence or symptoms in 3-year follow-up. The patient provided consent for publication.

Challenges, Learning Curve, and Safety of Endoscopic Endonasal Surgery of Sellar-Suprasellar Lesions in A Community Hospital.
Endoscopic endonasal surgery (EES) for the management of sellar, suprasellar, and anterior skull base lesions is gaining popularity. Our aim was to analyze and present the clinical outcomes of EES for the management of these lesions in a community hospital setting. ⋯ EES provides an effective and safe surgical option with low morbidity and mortality for the treatment of sellar, suprasellar, and anterior skull base lesions in a community hospital setting.

The interlaminar fusion combination involving C1-C2 screwing fixation is one of the most effective techniques for atlantoaxial dislocation or subluxation, and the bone graft is usually stabilized by wiring constructs. However, some adverse events were reported during the insertion of sublaminar wiring, such as accidentally damaging the spinal cord or dura. Thus we used the miniplate to stabilize the harvest bone graft on the C1-C2 laminar, which led to a shorter operation time and prevented spinal canal violation. This study investigated the safety and efficacy of the novel surgical technique, namely miniplate-augmented interlaminar fusion. ⋯ Miniplate-augmented interlaminar fusion with C1-C2 screwing resulted in excellent fusion rates with a considerably low probability of complications. Hence this novel technique for bone graft fixation with atlantoaxial screwing has a good efficacy and safety and can serve as an alternative for bone graft fixation during C1-C2 fusion.

Contributions from Latin America to the global literature are scarce; until 2011, spine surgeons had published 320 articles in indexed journals. ⋯ Scientific publications by AMCICO members are scarce, with a per capita annual index of 0.05 from a total of 441 articles in indexed journals. Second, the impact factor of these journals is low, with a mean value of 0.53. Further strategies should be implemented to increase the number and track the record of Mexican contributions to the scientific literature.
