Tuberculum sellae meningioma: Is there an ideal approach?

BACKGROUND: Tuberculum sellae meningiomas is a serious challenge for neurosurgeons. It accounts for up to 10% of all intracranial meningiomas. The difficulty in surgically excising a Tuberculum sellae meningioma comes from its anatomical relationship to the optic nerves and chiasm and to the anterior cer...

Resonancia magnética en pacientes con tumores más frecuentes en la región selar
Magnetic resonance in patients with more frequent tumors in the selar region

Medisan; 21 (6), 2017
La resonancia magnética constituye el examen ideal en pacientes con presunción clínica de tumores en la región selar, pues no emite radiaciones ionizantes y debido a su visión multiplanar y discriminación tisular, posibilita adoptar una conducta terapéutica adecuada y un seguimiento sin riesgos en...

Simultaneous meningioma and brain metastasis from renal cell carcinoma - a rare presentation. Case report

Säo Paulo med. j; 135 (3), 2017
ABSTRACT CONTEXT: Brain metastases are the most common tumors of the central nervous system. Because of their high frequency, they may be associated with rare situations. Among these are tumor-to-tumor metastasis and an even a rarer situation called simultaneous brain tumors, which are more related to p...

Postoperative otorhinolaryngologic complications in transnasal endoscopic surgery to access the skull base

Abstract Introduction: The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (c...

High expression of anti-apoptotic genes in grade I and II meningiomas

Expression of merlin, NDRG2, ERBB2, and c-MYC in meningiomas: relationship with tumor grade and recurrence

Braz. j. med. biol. res; 49 (4), 2016
Meningiomas are common, usually benign tumors of the central nervous system that have a high rate of post-surgical recurrence or regrowth. We determined expression of the proteins merlin, NDRG2, ERBB2, and c-MYC in meningiomas using immunohistochemistry and assessed relationships between protein expressi...
