Background:
The occipital transtentorial (OT) approach is well-established approach for pineal region tumors and can be of choice for the lesions located around the suboccipital part of tentorium such as the quadrigeminal plate, posterior part of thalamus, tentorial surface of cerebellum, splenial region, posterior falx, and lesions around the tentorial incisura. However, it is not very much extensively used in the above-mentioned locations other than the pineal region.
Methods:
Thirty-one patients of pineal region lesions were operated by OT approach, the role of conventional preoperative evaluation of the anatomy of the venous sinuses, deep venous system, and tentorial angle was investigated.
Results:
A variety of lesions were operated using this approach achieving gross and near total resection in majority of the cases (76.6%), with acceptable postoperative mean modified Rankin scales (1.8).
Conclusion:
The OT is a preferable approach for pineal region lesions for patients of all ages and can be tailored for achieving high resectability rates irrespective of the status of the deep venous system and tentorial angle, with reasonable postoperative surgical outcome.
We report a case of giant cell glioblastoma (GCG) in a 13-year-old child with clinical features and family history of neurofibromatosis type 1 (NF1). To the best of our knowledge, only two cases of GCG have been reported in a scenario of NF1, and only one of that was in a pediatric age group. A report on our case is presented here along with a review of literature.
Meningiomas are one of the common brain tumours which have origin for arachnoid cap cells. Extradural meningiomas are rarer variants classified into primary and secondary in nature based on their source of origin. The common location of primary extradural meningiomas is head and neck with paranasal sinuses being a common site in head and neck. The treatment of choice lies with complete excision of tumour which usually follows a good prognosis and low rates of recurrences. Current literature is scarce about primary extradural meningiomas with majority being case reports or short case series only.
We here present a case report of a primary extradural meningioma of right frontal and ethmoidal sinus treated by surgical excision. This case report adds on to the current knowledge of literature about primary extradural meningiomas.
Summary
A 28 year old male presented with chief complaints of right eye proptosis and right frontal headache with no neurological deficit reported to our centre with a trans nasal biopsy report of his lesion done elsewhere to be psamomatous meningioma Grade I. On reviewing his MRI Brain and paranasal sinuses, a totally extradural space occupying lesion in right frontal and ethmoidal sinuses communicating into intracranial cavity pushing right frontal lobe up and extending into roof of right orbit was found. Patient underwent right frontal craniotomy with complete excision of tumour with subsidence of proptosis in immediate post operative period.
Primary extradural meningiomas are rare entities with scarce literature available. We write this case report to add on to current literature available and also briefly discuss the literature review known currently.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
