Thoracic spine schwannoma presenting with traumatic spinal cord injury: A case report
CONCLUSION: Thoracic spine schwannomas are difficult to early diagnose unless there is a clinical suspicion. Initial presentation as bleeding after trauma was not described before. This presentation should be kept in the differential diagnosis of any patient with an acute neurological deficit without trauma signs on admission imaging.PMID:34221582 | PMC:PMC8247680 | DOI:10.25259/SNI_856_2020 (Source: Surgical Neurology International)

Intradural extension of mucocele secondary to giant frontal sinus osteoma: Diagnostic pitfalls
CONCLUSION: Intracranial extension of mucocele led to meningitic hydrocephalus, prompting us for VP shunt. Resulting tension pneumocephalus revealed what was missed on preop CT, a small pocket of air adjacent to osteoma intracranially. Therefore, this case underscores the importance of obtaining a preoperative CT FESS to elaborate the origin of osteoma, thus planning approach differently.PMID:34221583 | PMC:PMC8247709 | DOI:10.25259/SNI_11_2021 (Source: Surgical Neurology International)

Rosai-Dorfman disease mimicking images of meningiomas: Two case reports and literature review
CONCLUSION: Intracranial Rosai-Dorfman tumors should always be remembered as differential diagnosis of meningiomas since they are similar radiologically and macroscopically. Once remembered and diagnosed, the lesion must be treated following the same pattern of resection done in meningiomas and, treatment's differences will not occur in the surgical excision technique, but in complementary chemotherapy implementation, radiotherapy, and even with radiosurgery aid, depending on the case. Thus, it is possible to obtain better results than with just the isolated surgical procedure.PMID:34221623 | PMC:PMC8247728 | DOI:10.25259/...

Inflammatory myofibroblastic tumor masquerading as an anterior choroidal artery fusiform aneurysm
CONCLUSION: Intracranial IMT remains a rare and poorly understood entity. The present case demonstrates a novel presentation of IMT in an adult patient and exemplifies the heterogeneity of the disease presentation.PMID:34221627 | PMC:PMC8247755 | DOI:10.25259/SNI_113_2021 (Source: Surgical Neurology International)

Extensive titanium mesh invasive cranial fibrous dysplasia
CONCLUSION: Recurrence of FD, involving cranioplasty titanium mesh, is extremely rare. It suggests local invasiveness of lesion. Recurrence can be prevented by excision of lesion with free bony margins.PMID:34221629 | PMC:PMC8247748 | DOI:10.25259/SNI_63_2021 (Source: Surgical Neurology International)

Intravenous versus inhalational anesthesia trial for outcome following intracranial aneurysm surgery: A prospective randomized controlled study
CONCLUSION: The long-term neurological outcome of good grade aneurysm patients undergoing craniotomy and clipping remains comparable with the use of either propofol or desflurane. The effect of the two anesthetic agents on the various clinical parameters and the biomarkers of brain injury is also similar.PMID:34221630 | PMC:PMC8247687 | DOI:10.25259/SNI_342_2021 (Source: Surgical Neurology International)

Cerebellar metastasis of a Liposarcoma: Case report and literature review
CONCLUSION: Cerebellar metastasis of LPS is uncommon; there are only a few cases reports with the literature reviews describing orbital or skull base metastases, but not in the cerebellum. Our case allows us to remember that neurological symptoms, no matter how subtle, in patients diagnosed with LPS, a secondary affectation of the central nervous system must be ruled out, even though it is a rare location. The findings of distant disease in LPSs, allow planning oncological treatment options and targeted radiotherapeutic.PMID:34221631 | PMC:PMC8247727 | DOI:10.25259/SNI_82_2021 (Source: Surgical Neurology International)
